Secrets of Home Theater and High Fidelity - Best of Awards 2017
The OPPO Sonica DAC is a state of the art, fully balanced DAC using Sabre’s top of the line 32 bit DAC chipset, implemented with excellent digital and analog engineering.

It combines this level of core engineering with a very complete set of streaming and USB connectivity. It can stream 24 bit 192 kHz files from DLNA servers over WiFi and USB, plus DSD64. When connected via USB, it can decode PCM at 32 bit, 768 kHz, and DSD512. Streaming Apple Lossless files from my DLNA equipped network attached storage device, it worked flawlessly. The free OPPO Sonica app works on both iOS and Android devices, and provides an effortless, convenient way to access your music. This is a significant step up in audio quality and features compared to the OPPO HA-1 headphone amplifier and BDP-105 Blu-ray player.

The OPPO Sonica DAC


Oppo Digital Sonica DAC

  • State of the art digital decoding of pretty much every file format there is, and even some that don’t even exist yet (find me a 32 bit, 768 kHz PCM file someplace?).
  • State of the art WiFi connectivity and streaming functions, along with traditional asynchronous USB and even more traditional Coax and Toslink inputs.
  • Oppo Sonica app allows control of the Sonica DAC from your phone or tablet.
  • Fully balanced analog and digital signal path.
  • Digital volume control allows you to use the Sonica DAC as a preamp. It even has an auxiliary analog RCA inputs to allow the use of one additional source.
  • At $799, a super value.

For many years the separate DAC as an audio component was declared dead. But with the ascendency of computer based music, especially now for audiophile ultra-high resolution files, the DAC has been reborn. OPPO has always been a company that has offered excellent value for audiophiles. I’ve been using a BDP-105 Blu-ray player as a USB DAC now for several years. Now, OPPO has finally released a stand-alone DAC, the Sonica DAC (although you could argue their HA-1 headphone amplifier was sort of a stand-alone DAC).

DAC, Streaming, Preamplifier, DACs Reviews 2017

The Sonica’s spec sheet reads like a serious assault on the best you can do with a DAC these days: Quad ESS ES9038PRO Sabre DAC chips implemented in a fully balanced topology, an oversized power supply with toroidal transformer, and the ability to decode basically every file format there is over USB and streaming connections. It even does native DSD decoding up to DSD512 for the USB input (DSD64 for streaming). You can’t even get DSD512 source material yet, as far as I know. This all seems straightforward until you get to the price. $799. Really? That’s standard OPPO. Offer pretty stupendous specs, then slap a relatively small price on it. As usual, the question is, does it actually live up to the specs. In the case of the Sonica DAC, the answer is an unequivocal yes. This is a wonderful sounding DAC that is supremely convenient. I’m not sure I can continue without it.

Design and Setup

Like every OPPO product, the Sonica DAC is a beautifully made piece of hardware. The fit and finish is first rate. Even better than most “high end” electronics, in my opinion. The quality and feel of the front panel and controls is second to none. It is a relatively small unit from the front panel, but will a full depth case allowing room for the large linear power supply mounted on the left side of the chassis. About 1/3 of the internal volume of the Sonica case is taken up by the power supply, as it should be in a proper piece of HiFi equipment. A central board takes care of all digital signals and control, while the analog output is separated on its own board on the right of the case. A rear mounted daughterboard handles the inputs and outputs. The signal path is fully balanced, including the use of quad DAC chips implemented in a balanced configuration. The RCA outputs are generated by summing the balanced outputs, so they reap much of the benefits of the balanced topology too. A volume control on the front panel uses the extra bits provided by the 32 bit DACs for about 48 dB of volume control from full scale before you start to lose anything even with 24-bit source material. This volume control can be turned off if you use a traditional preamp like I do. The volume control bypass can be set to be output specific too, so you can use one output with a preamp and the other without. There is one RCA single ended output and one XLR balanced output.

The OPPO Sonica DAC rear panel

There are single ended and balanced outputs, coax, optical and USB inputs along with and RCA auxiliary device input, an Ethernet connector for wired internet connection and an IEC power jack. A USB-A port for mass storage device connection and 12V trigger inputs and outputs are also offered.

It’s in the input department where the convenience of the Sonica shines. There are traditional RCA coax and Toslink optical inputs that work up to 24 bit 192 kHz, and also accept up to DSD64 in DoP v1.1 format or in raw, native DSD format. The USB input accepts basically everything. Even things that don’t yet exist. PCM in every combination you can think of all the way up to 32-bit 768 kHz and DSD up to DSD256 in both native and DoP and DSD512 native only. I don’t think any source material exists in DSD512 or in 32-bit 768 kHz format. Yet. There’s a USB-A port on the front that can talk to USB mass storage devices (thumb drives and hard drives) that supports basically every computer audio format (even OGG!) up to 24 bit 192 kHz and DSD64. And then there’s the streaming.

Secrets Sponsor

There’s Bluetooth and Apple Airplay to casually stream from your phone, tablet or computer. But best of all, the Sonica is a WiFi device that can see your wireless network. And your DLNA servers. The streaming input accepts the same file formats and sampling rates as the USB-A port. Again, basically every format you can think of up to 24 bit 192 kHz and DSD64. All my music is on a Netgear ReadyNAS Duo network attached storage device. In the past I managed to set up my iTunes library to use this remote file location, then played the music back with PureMusic software and the OPPO BDP-105 connected as a USB DAC. The Sonica allows me to bypass all this complexity. The NAS has a DLNA server which I enabled and the Sonica was immediately able to see it. Using the OPPO supplied app (free for iOS or Android) I could browse my library and control playback from my phone or tablet with ease. No computer or wires needed. It’s fantastic.

With separate PCBs for the power supply, digital section, analog output section and inputs.

For this test, I used the OPPO in only one mode. There are so many options it would have taken me forever to test them all properly. So I chose the one I wanted to work well and tried that, which was the network streaming input. All my music is in Apple Lossless format in my iTunes library located on my rather old Neatgear ReadyNAS Duo device. This device is known to have a “not the best” implementation of DLNA. It doesn’t work reliably with many other DLNA devices. But it works perfectly with the Sonica DAC. I put the DAC on my wireless network with no trouble. Getting the device on your network requires the use of the Sonica app on an Android or iOS device. After putting the DAC into network setup mode, the setup is continued on the app. My DAC immediately saw my DLNA server and I was able to start streaming files.

There’s also an Ethernet connection on the back, which is set up exactly the same way if you want to use a wired connection. I set up both an Android tablet and my iPhone to operate as controllers. Since all my music is 16 bit 44.1 kHz and 48 kHz and 24 bit 88.2 kHz, 96 kHz and 192 kHz, there would be no gain for me to go to the USB input directly connected to my computer. It is worth being careful that your DLNA server streams files in native format without any sort of transcoding or adjustment. My old NAS has no options here, it can ONLY send files in native format, so I was always sure I was getting an unchanged file. Since the files are sent natively, the transmission is fundamentally asynchronous. So no worries about jitter or signal degradation. Unlike the OPPO Blu-Ray players, the Sonica DAC cannot stream content from an SMB server, only DLNA. I used the RCA outputs of the Sonica DAC to connect to my single-ended-only Rogue RP-1 preamp. Since I am using a separate preamp, I disabled the volume control of the DAC for my review.

The Sonica DAC does not come with a traditional remote control. That’s all done with the OPPO app, which can control browsing of streamed and USB connected mass storage devices and the volume control if enabled. It also controls OPPO’s Sonica WiFi speakers, which you could use as a whole home music system if you’d like. It also allows access to internet streaming services like Spotify and Tidal. The app cannot turn the DAC on and off, however. You still need to drag your butt out of your chair for that. There are 12V trigger inputs and outputs for system control and even a grounding lug for taking care of hum should it arise.

The OPPO Sonica App interface

Another useful feature is a set of RCA analog inputs that will allow the connection of another source to the Sonica DAC. The DAC can then either play this input back through its own analog outputs or stream it to other Sonica devices. The penalty is that this input needs to be digitized to go through the Sonica’s volume control and be available for streaming. The input is digitized with a TI PCM1808 ADC chip at 24 bit 48 kHz. This input is not intended as a high quality “preamp” input, just as a way to add an analog source to a whole-home Sonica audio system.


Random Access Memories

Daft Punk “Random Access Memories”

The initial impression I got of the Sonica DAC was similar to that of the BDP-105, but the more I listened, the more differences revealed themselves. Initially the Sonica was a bit bright. It took a week or so for the DAC to break in and smooth out. Once it did, it was clear that the Sonica presented quite a bit more resolution, sharpness and detail than the BDP-105.

On well recorded albums, like many of my high bit rate albums, this added sharpness and detail was very rewarding. On more poorly recorded material, the detail and resolution could be a double edged sword. On Daft Punk’s Random Access memories, the differences in the microphones used to record Giorgio by Moroder were more apparent than ever, even more so than with my high quality office headphone rig, which was very unexpected.

Morning Phase cover art

Beck “Morning Phase”

The sound of the Sonica DAC was completely seamless. Many components have particularly good bass, midrange or treble. The Sonica DAC presented all parts of the tonal spectrum equally, with no one part of the experience calling any undue attention to itself. The soundstage is wide but not unnaturally so, with a middle of the road depth presentation.

With my Gallo Reference 3.5s, the soundstage was typically about the same distance away as the speakers, maybe a little farther. Width was 2-3 feet past the speakers to the left and right, with height about a foot above the speakers. On my 24 bit 96 kHz recording of Beck’s Morning Phase, “Say Goodbye” was haunting. The detail of Beck Hansen’s voice, acoustic guitar and percussion was about as good as it ever gets. Here, the detail and resolution squeezed every last bit of excitement, life and realism out of the recording. It really took my system to another level.

GIRL cover art

Pharell “GIRL”

The BDP-105 is good, with many of the same tonal characteristics and presentation, but the Sonica DAC pushes that performance up a notch or two. Play a “bad” recording, and you’ll know it, though. I have a HDTracks download of Pharell William’s GIRL. This is a very bright album. Particularly the popular song “Happy”, which seems to be purposely recorded brightly to give an upbeat sound even with low quality headphones.

When I first got the Sonica, the song was almost unlistenable. Once the DAC broke in, matters were a lot better, but I was able to hear every last questionable decision the recording engineer made.

Oddity cover art

David Bowie “Oddity”

My 24 bit 192 kHz recording of David Bowie’s Space Oddity revealed all the compromises of the original analog tape recordings remastered to high bit rate digital. Still wonderful to listen to, but you do hear every last little flaw. Another thing to keep in mind is that the Sonica’s detail, resolution and completely un-rolled off treble will call attention to any shortcomings of your downstream electronics or speakers.

The combination of my Rogue RP-1 preamp and NewClear NC1000L IcePower amplifier was a good balance between detail retrieval, control and smoothness to match well with the OPPO. It was the combination of the performance of the Sonica DAC, along with the effortless operation of its DLNA streaming services over WiFi, all controlled with the excellent Sonica app on my tablet that kept me coming back for more. I was listening to my system more, and getting more enjoyment out of it. And that’s the whole point, isn’t it?

On the Bench:

Measurements were made with my M-Audio ProFire 610 firewire audio interface and Spectra Plus FFT software. I drove the Sonica DAC with a 24 bit, 192 kHz SPDIF signal from the coax outputs of the ProFire 610, and measured the analog output of the left balanced output. The signal was input to the DAC as 0 dBFS, with the gain of the sound interface input tuned to deliver the maximum dynamic range.

Distortion spectrum with a 50 Hz 0 dBFS input

Distortion spectrum with a 1 kHz 0 dBFS input. THD+N rises very slightly to 0.004%.

Distortion spectrum with a 10 kHz 0 dBFS input. THD+N is a still excellent 0.006%.

Distortion spectrum results are excellent, with very low absolute levels of harmonic distortion. In addition, this distortion is concentrated in the 2nd and 3rd harmonics, dropping significantly in higher orders. This is generally a good sign of a component that sounds good. In addition, these numbers are very similar to what I get when I run a loopback test, meaning connecting the ProFire 610 output directly to the input with just a cable. This means the results above should be treated as upper limits, since a significant amount of the distortion shown above is likely to come from my measurement tool itself.

Intermodulation distortion

The intermodulation distortion results are also very good, with mixing products about 100 dB down from the fundamental and total IMD measured at 0.004%. Again, this result is similar to a loopback test.

Frequency response

Frequency response is flat as a pancake to the limit of the sound interface. The gentle rise towards 96 kHz and the sharp cutoff at 96 kHz are an artifact of the measurement.

The noise floor was not measurable. I ran the FFT software with the Sonica DAC turned on and off but with no input signal and got the same result. What you see here is the spectrum with the OPPO Sonica turned on but without a digital input signal.

In summary, these measurements are without fault. They are near or at the limit of my test equipment to measure.


Noise floor of the OPPO Sonica DAC

THE OPPO SONICA DAC Might Be One Of The Best Value Audio Components Available Today, Offering Superb Audio Performance And An Unmatched Feature Set.

  • Superb sound quality with excellent resolution, sharpness and detail retrieval.
  • Excellent build quality and styling.
  • An unmatched set of features including the ability to decode pretty much every file format at bit rates and depths that don’t even exist yet, and exceptional streaming features from both local servers and internet sources though WiFi or Ethernet.
  • Very convenient operation from the OPPO Sonica app for Android or iOS.
  • Measurements are flawless.
Would Like To See
  • Pretty much nothing. I don’t have a single complaint, really.

As I was coming to the end of the review I started to wonder how I could live without it, both the sound and the convenience. I want to buy this DAC. But OPPO is also coming out with a new high performance Blu-ray player, the BDP-205. This player, the successor to the BDP-105, will offer the same or better video performance of the new BDP-203, but with much of the high performance audio of the Sonica DAC. It will use the same DAC chipset, USB interface and analog architecture as the Sonica DAC on the audio side. It will also be able to play from a DLNA server (in addition to a SMB server, which the Sonica DAC cannot do), and accept and decode many (if not all) of the same file formats and bit rates. It will not offer Spotify or TIDAL streaming, Airplay, Bluetooth or integration with Sonica Wi-Fi speakers like the Sonica DAC, however. And it’s of course still unclear whether the audio performance will be as good as the stand alone DAC. My guess is the Sonica DAC will have the edge there because it doesn’t have to coexist in a chassis with all that video hardware or deal with multi-channel analog outputs. If I had an audio only system, and didn’t own any SACDs, the decision would have already been made. There would be no way I would let the Sonica DAC leave my system. As it is, I think I’ll wait to see what the new BDP-205 will deliver. But you can bet that I’ll buy one of the two. Because I really can’t live without it.

  • NotReallyHere

    I’m old fashioned, and would like to have an remote.

  • David Musoke

    Nice review …but your 50Hz plot should really be titled 60Hz 🙂

  • Forrest

    I enjoyed your review of the Sonica DAC. Inasmuch as Secrets has also reviewed the Emotiva XMC-1 would it be possible for you to compare the sound quality of the Sonica DAC to the XMC-1? For me, at the price point, if the Sonica DAC was superior sonically, it could make more sense to utilize a Sonica DAC with the XMC-1 than upgrade to a new processor. Thanks

  • lpjakobnow

    I would love to purchase this Oppo Sonica DAC but I will not purchase a new DAC that does not support MQA, Tidal Masters. I wish Oppo would get on the MQA supported list. I instead purchased two Mytech Brooklyn DACs. A long term Oppo customer who is disappointed with this limitation.

  • T Grisham

    Thank you for your review. I recently began using the Teac UD-503 which uses the VERITA AK4490 DAC, with dual mono configuration. The AKM sounds different to my ears than the Quad ESS ES9038PRO Sabre DAC in the Sonica. I have read reviews and I agree that the Sabre DACs have excellent resolution and clarity but if given the wrong components and or poor quality sources can sound too bright. I also use a tubed pre-amp (Modwright) and Class D mono amps (Wyred4sound SX 500) so our systems are similar. I have not heard the new Sonica DAC. I do love the sound of the TEAC. It is revealing and detailed and never brittle. It sounds more “real” to me than the Sabre DACS I have heard. Will you have an opportunity to review the Teac? I hope so.

  • starkim

    Hi I am planning to get one Mytek Brooklyn DAC. What steamer would you suggest which can output MQA with AES/EBU to Mytek?

    Auralic Aries would be the best budget for me but it’s MQA support is still under pending status. Aurender N10 is nice but it’s overbudget for me.

  • Yatra

    Thanks! Reading at this review, I now very much look forward to the BDP-205 review !

    Else, would it be possible to include a section with comparison between the product reviewed and others at same price point ? This is often missing in reviews. Thanks

  • Chris Groppi

    That would be nice, but extremely difficult. I would have to have all those components present to compare, which I never do unless we’re doing a “shootout” review where we’ve planned that,

  • Chris Groppi

    I’ve never personally listened to the XMC-1. The best option would be to buy a Sonica from Oppo and return it for a full refund if you’re not satisfied. The only judge that really matters is you.

  • Chris Groppi

    Oops :).

  • lpjakobnow

    I was hoping for one DAC to do it all from Oppo; streaming without a PC and support of MQA and all HiRes formats…but unfortunately, as we have been discussing, no support for MQA. Therefore my solution has been the two Brooklyn DACs connected to two dedicated PCs and pre-amps (via balanced inputs) for HiRes NAS files and streaming of MQA via Tidal app and Roon app as solution for critical listening. For general whole house/party/background music, I use Blue Sound Node 2s connected to pre-amps (via RCA inputs) controlled via Kindle Fires located through out the house.

  • Forrest

    Given the vast number of DACs available and the near impossibility consumers face relative to listening to a DAC prior to purchase, reviews are critical. However, reviews with no points of comparison may be entertaining, but have little value in assisting a consumer with the decision to purchase. Surely you and others at “Secrets” have enough experience with other DACs to provide comparisons of some sort.

  • Jamie Anderson

    That of course would be irrelevant if this so-called review is simply an ad for oppo, which I am 100% certain it is.

  • Paul Lane

    No MQA no sale..

  • Chris Boozer

    mqa can be decoded in a media pc, gigabyte motherboards with dac-up 2 have special usb outputs with filtered power designed for high quality dacs. less than a hundred bucks for either intel or amd with this feature. I went with an am4 amd 8 core solution with ssd storage 16 gb of ram an uninterruptible power supply with additional power conditioning for this dac, the music server pc only used foir music all seperately filtered power. mqa decoded by the pc output to dac, martin logan electro stats, dual svs sealed subs in stereo bass configuration and mono block 200 watt amps with xlr inputs from outlawaudio. it sounds amazing…..

    “Even things that don’t yet exist. PCM in every combination you can think of all the way up to 32-bit 768 kHz and DSD up to DSD256 in both native and DoP and DSD512 native only. I don’t think any source material exists in DSD512 or in 32-bit 768 kHz format.”

    There is a growing catalog of DSD256, and IMO THIS is where the real magic, if any, comes from DSD. You see, regardless of noise shaping trickeration and massive ‘specified’ signal to noise ratio or ‘resolution’, DSD, or let’s dispense with the trademarks and call it what it is, single bit delta sigma, which DAC chip makers gave up on a long time ago for multi-bit Delta Sigma and/or high sample rate multi bit noised-shaped PCM. All semantics, but, in the end single bit Delta Sigma was discarded a long time ago.

    But hey, now its back! And you might think after that rant above I am a hater. Far from it. I can hear the potential. But the real resolution just isn’t quite there. We are talking about a 100 percent time splicing format with 1 bit delta sigma. All the actual resolution is achieved by averaging. Given a certain number of full on and full off signals 1 bit signals, I can equal the resolution of any multi-bit sample in the same time period. Lets imagine we have a light bulb that can effectively show 65,536 gradients every 44,100 of a second and MUST do so, that is, change each second to a different gradient. It has an internal digital engine that accomplishes this. Now, imagine its the year 4000 AD and I have a bionic arm and a superbrain, and I can flick the light switch on and off as much as 65,536 times a second. I can effectively by switching from full-on to full off the appropriate number of times any gradient the internal light bulb computer can show. By averaging the 65,536 single, individual switches every 44,100 of a second, I have equaled the resolution of the internal bulb PC.

    Now this is all well and good, if our full on/full off switch is fast enough. But alas, our current on/off 1 bit delta sigma audio switches would have to run at 2,890,137,600 bit-switches per second to achieve equivalent REAL resolution at CD. (Not noise shaped hocus pocus)

    On a related note, since 1 bit Delta Sigma is indeed time splicing, the situation is much better a low audio frequencies and much worse at high frequencies. Also, as the volume lowers, the situation gets even worse. Thorsten Loesch put this to the test but creating DSD64 test files and looking at the on the scope. the high frequency sine waves at less than full volume were a COMPLETE NIGHTMARE to look at. A garbled up mess.

    Now, again, you are thinking I am a BIGTIME DSD HATER.

    NO…. In spite of all the above, I really, really like the sound of DSD, especially at the 256x oversample rate. Because first of all the extra equivalent 2 bits of resolution over DSD64 is worth much more than it may appear on paper. And now the real reason.

    THE FILTER. It is my opinion that the very gentle filters and the lessened smearing, ringing, etc is a HUGE advantage over PCM at this point. Even considering the resolution issues of DSD. Even ESS chipsets like the one in the OPPO that mucks up DSD with unnecessary conversions, re-samplings and re-modulations benefits from the very nicely implemented rolloff filter.

    This is also a HUGE reason upsampling everything to DSD256 or DSD512 is GREAT. Granted we can’t control what happens on the creation end, but at least on OUR end we can convert the audio with the best, least offensive filters as possible.

    Now, I can hear some of you screaming, just go NOS PCM! And you are preaching to the choir. Its all in the filter, or the lack there-of in NOS case. I will say this, though. Almost all PCM recordings, CD quality and higher, start out in a delta-sigma ADC. I think once the Pacific Microsonics ADC’s bite the dust, that will pretty much be it for true PCM AD conversion.

    WHEW! And back to the reason I started this whole wreck of a soapbox speech, is WHY a DAC needs to support PCM 768. For those who can’t do ASIO native. For those who still need to do DSD over PCM. If you want DSD256, and you are one of those people, you are SOL unless you DAC can miraculously accept PCM768.

    No MQA and No Remote.. So No..
