The MHT300 Home Theater Receiver is only the third AV receiver ever made by McIntosh. Will the MHT300 Home Theater Receiver live up to the legend and maintain the hallmark of rugged design and quality the company is known for? Here is my take.

McIntosh MHT300 Home Theater Receiver

McIntosh has been in the AV business for nearly 75 years. Their amplifiers were at Woodstock. Their distinctive blue, green, and glass faces have been adorning audio shows for, well, as long as there have been audio shows. But in all those years they have only made two other A/V receivers. They don’t design and produce products willy-nilly every year and their products are not for the “common man”. For many of us, it takes years to claw our way up to the top of the audiophilia mountain…and when we get there, McIntosh!

Introduction

Known for years as the pre-eminent maker of powerful tube amplifiers, McIntosh has branched out into a full line of audio products from surround processors, speakers, and disc players to a line of audio products found in the higher-end Jeep vehicles. The MHT300 Home Theater Receiver is not inexpensive, but when compared to the cost of McIntosh surround separates (in this case, seven channels worth) you get a pretty good bang for the buck. What got me excited about the MHT300 was its simplicity. A pre-pro with seven very powerful amps that can expand into four overhead Atmos channels, dual subwoofer outputs, and built to become something you can pass down to your grandkids, all in one box. The setup process was easy and sound quality was exceptional for both movies and music. I could get rid of my multiple amps, reduce cable clutter behind my equipment rack, and enjoy the prestige of owning a McIntosh product. I am looking for that elusive less is more type of product and the MHT300 just might be what I’m looking for.

Design

McIntosh MHT300 Home Theater Receiver

If not for the FM connection on the back, the MHT300 could almost be classified as an integrated amp. Though the MHT300 is built to last and has ample power, it does come with some caveats, which I will dive into later. When unboxing the MHT300, I was aware of how light the unit was. With seven Hypex Class D modules, the weight is greatly reduced. On the back end, you notice four HDMI inputs that are capable of up to 8K/60 and one HDMI eARC output. Do not expect to play the latest games on this unit (not that the MHT300 is intended to appeal to gamers). There are two coaxial and two optical inputs. No analog inputs are present unless you want to purchase an analog-to-digital converter. There is the FM antenna input (I think that’s a McIntosh first) and two trigger-outs for powering on other devices. The network jack may be used to set up the MHT300 and is not used to connect to the internet. Alternatively, the front panel VFD may also be used for setup. The binding posts are gold plated and a wrench is provided to tighten them onto speaker wire. Each speaker out has a jumper above it should you want to use another processor or amp other than the MHT300. This means it can function as a processor or multi-channel power amplifier. Four height channel outputs are also included which require outboard amplifiers should the seven internal amps all be in use. Or you could connect them to the jumpers and feed them into MHT300 if you have a 5.X setup. The front panel is mostly glass framed with aluminum. The knob on the left is a source input selector and for menu setup, though that process is better done with the computer with the MHT300 connected to the same network. The knob on the right is OFF/ON and volume control.

McIntosh MHT300 Home Theater Receiver Remote
These things can be done via the included remote, but it can be a bit clunky, especially in a dark room. The remote is slender and feels good in the hand, but it is not backlit, which I feel is a must-have for home theater purposes. It also sports an ON button on top and the OFF button is four buttons below it. Why not just one button? That’s a bit strange and takes some getting used to in a darkened room. The DACs inside are 32-bit and each amp delivers 120 watts into 4 ohms and 150 watts into 8 ohms, all channels driven. That’s a lot of horsepower!

Setup is best performed on a computer that is on the same network as the MHT300. I used my Mac (NOT the same company) and typed in the IP address that was displayed on the MHT300 with the remote. Once connected, the setup process took less than 10 minutes. I did get tripped up on Dolby Speakers. What are those? They ended up being the ATMOS speakers either found overhead or the kind mounted atop tower speakers that bounce sounds off the ceiling, if you are using them, so I had to answer NO for it to work for my system. Dirac room correction (another McIntosh first) is one of the best room correction products on the market. It does everything Audyssey XT32 can but also compensates for time domain inconsistencies. You must download it onto your computer and follow the instructions. If you have trouble, there are tutorials on YouTube for getting the best results as Dirac can be a bit finicky. Once all the computer stuff is done, you will rarely have to go back into it, unless you are a tweaker.

McIntosh MHT300 Home Theater Receiver Setup
The sound character of the MHT300 seemed neutral with a little bit of zing missing on the top end. It doesn’t have the warm McIntosh sound that I was expecting, perhaps due to the Class D design. A few patented safety features like Power Guard (prevents distortion clipping) and Sentry Monitor (shut down if speaker wires short) are included with this product. There is no fuse that will soft blow inside. Each channel has a green indicator light under it that changes to amber in a fault situation and when Dirac is engaged. It has a front panel light indicator as well.

Over time, certain missing features became apparent. Mind you, these are just my opinions, you may not care about these things, but here we go: First, no internet radio. No analog inputs. The need to purchase another amp or two for the overhead speakers. No voice assistant (Siri, Alexa, etc.), no backlit remote, no ability to decode DSD unless converted first to PCM, no on-screen display for setup on the fly, and the info display is a bit too minimalistic. No Imax Enhanced. Nothing for gamers. No Bluetooth or Wi-Fi. No balanced inputs. All of this may seem to be too much compromise for an $8,000 receiver, but it may not be aimed at my personal tastes.

Compared to other AV receivers, the MHT300 looks a bit plain. If, however, you are a fan of McIntosh products, it can be considered a value product because their other processors combined with even their most modest amplifiers would easily exceed the cost of a MHT300. If I already had a rack of McIntosh gear, I wouldn’t blink at this product. It is all in how you view value. It does the basics well with tons of power and it is a McIntosh.

In Use

With movies, the MHT300 performed flawlessly and switched to Dolby Atmos without a hitch. The dialog was always very articulate with excellent mid-bass clarity. That extra sizzle and zing of bullets lacked a bit of air and tended to sound attenuated. I like to flinch when a bullet whizzes by my head. I wasn’t quite getting that. Bass was very powerful, and I never felt the MHT300 was working hard. The unit generated some heat over extended use, but not like other receivers I have owned in the past.

Movie

McIntosh MHT300 Home Theater Receiver Movies
DUNE has lots of warfare and an amazingly powerful soundtrack by Hans Zimmer. I anxiously await Part 2’s release once the picket lines fold up. The sound was enveloping and well-presented by the MHT300. With Dirac engaged, I had a surround bubble that made the movie even more exciting than just the visual beauty of it all. I wish the MHT300 had a little more information that could be displayed on the screen, but what is presented is useful, but minimal at best.

Lately, my “go-to” scene for home theater testing is the shotgun scene from John Wick 3: Parabellum. The detail of shoving shells into the gun, the gut-punching sound of them going off, the tinkling of shattered glass, and the ejected shells hitting the marble floor are amazing. And all this chaos is in all seven channels at the same time, yet the MHT300 delivered the sound in a way that engaged you. Never did it sound like it was running out of juice and the impact of the bass was wonderful. I could play this 10-minute clip over and over and never tire of listening to it.

Music

McIntosh MHT300 Home Theater Receiver Music
I have an extensive collection of surround SACDs and DVD-As that allowed me to test for clarity and general cohesiveness of sound and the MHT300 passed with flying colors. I could not play a DSD file from my computer to the MHT300, and with no analog inputs, I could not use my PS Audio PerfectWave Direct Stream DAC. I found a workaround by downloading Qobuz onto my TV and streaming from there. Unfortunately, it topped out at 48kHz, and I paid extra for the higher-resolution formats. In the end, you’ll only be able to play CDs, as you cannot cast to the MHT300. For surround music, I have some old standbys like Breakaway by Art Garfunkel and A Young Persons Guide to the Orchestra by Benjamin Britten. Voices and instruments were dynamic and natural sounding. If you have an extensive surround catalog of music, the MHT will not disappoint. The FM tuner I did not test as I have not had an antenna in my system for over a decade.
