Lumagen Radiance XS-3D Video Processor

Chris Heinonen

Last year I looked at the Lumagen Radiance Mini-3D video processor and its interaction with ChromaPure software for automated calibrations. Paired with an older projector, it was able to provide an accurate grayscale, gamut, and gamma providing an image that was far more accurate than without it. Now, we take a look at the Radiance XS-3D video processor, which is a step up from the Mini-3D.

NAD M3 Integrated Stereo Amplifier

John E. Johnson, Jr.

If you look at the specs of most stereo integrated amplifiers, the rated RMS power output is between 60 watts and 120 watts per channel. This is lower than the power output of outboard power amplifiers, which typically are about 125 watts to 300 watts per channel. Monoblocks go all the way up to 2,000 watts output. One of the main reasons for this is that in an integrated power amplifier, the preamplifier circuit is situated very close to the power amplifier. Keeping the high voltage, high current power amplifier signal from inducting noise into the preamplifier circuit is difficult. NAD apparently has solved this problem with the introduction of their M3 Integrated Amplifier, which has a rated output of 180 watts per channel, at 0.004% THD+N, and clipping (1% THD+N) at 220 watts.

Toshiba 50L5200U LCD TV

Stephen Hornbrook and Chris Heinonen

Toshiba is targeting value with its L5200U line of LED LCD TV's.   The 50L5200U is a 50" 1080p set featuring a 120Hz panel with ClearFrame™ technology for crisp images and smoother movement.  Like most LED-edgelit TVs, the Toshiba employs a dynamic lighting system (DynaLight®) that adjusts output based on the image content.

Sony BDP-S590 Blu-ray Player

Chris Heinonen

Sony was the inventor and chief advocate of Blu-ray and has probably put more players into homes than any other company with the PlayStation 3.  However when we ran a pair of their players through our HDMI Benchmark, one of which is the subject of this review: the Sony BDP-S590.

Epson PowerLite Home Cinema 5010e LCD Projector

Chris Eberle

For several years now, Epson has been the undisputed leader in the LCD projector market. They took a technology that seemed forever destined for boardrooms and churches and improved it gradually, until it became hard to tell apart from high-end LCoS and DLP designs. Enthusiasts who would have never considered an LCD are now taking a serious look at Epson's offerings. One of them might be the 5010e, reviewed here.

NAD T 187 7.1 A/V Processor & T 975 Seven-Channel Power Amplifier

Chris Eberle

NAD, which stands for New Acoustic Dimension, was founded in 1972 with one simple goal: to reproduce sound as faithfully as possible. Eschewing bells and whistles, NAD products are all about simplicity, value and performance. From their earliest components, like the legendary 3020 integrated amplifier, to today's multi-channel amps and preamps, they have never wavered from this mantra. Here, we review separates: the NAD T 187 7.1 A/V SSP and the T 975 seven-channel power amplifier.

Runco LightStyle LS-100d DLP LED Projector

Chris Heinonen

For a truly immersive home theater experience, nothing compares to a large image that fills your field of view.  Unfortunately many of us don't have a room that will work for a projector due to space and throw limitations and are forced to make do with a far smaller plasma or LCD display.  Runco has a solution for those challenging situations with their LS-100d, a short throw, LED-based projector capable of producing a 100" image while being placed right up against the wall.

Optoma HD8300 3D DLP Projector

Chris Eberle

Now that 3D has become commonplace in HDTVs, projectors are following suit. Most of the new models introduced at CEDIA 2011 incorporate 3D into their feature set. While 3D has not lured me into upgrading my reference equipment just yet, I can't help but wonder when I might really want to watch Avatar in 3D. So, I managed to obtain the new Optoma HD8300 DLP projector which just happens to have 3D capability.

Wireless HDMI Round Up

Chris Heinonen

Now that our TVs are thin enough we often want to hang them on a wall, and manufacturers keep pushing the limits of thickness year after year. CES this year saw the advent of OLED TVs that are just millimeters thick as they no longer need backlighting systems, and serve double duty as a cheese slicer with their razor-thin profiles.

Accell UltraCat HD HDMI Extender

Sumit Chawla, Ph.D.

During CEDIA 2011, one technology that caught my attention was HDBaseT. It provided a solution to the all too familiar cable clutter problem. Below is a picture that I took at their booth which shows a set of cables whose signals could all be transmitted over a single Cat5e/6 cable at distances up to 100m.

Velodyne vPulse In-Ear Headphones (Earbuds)

John E. Johnson, Jr.

With the prevalence of portable music players to the point that you must be from Mars if you don't own one, there is a huge aftermarket for high quality earphones (headphones is the category, with over-the-ear headphones, on-ear-headphones, in-ear headphones, in-ear-earphones, and in-ear earbuds being the specific type of headphone one is referring to). Velodyne, renown manufacturer of subwoofers, not to be left out of this trend, has released a set of in-ear headphones called the vPulse....and best of all, they sound like Velodyne all the way . . . a.k.a. very, very good.

Anthem P2 Two-Channel Power Amplifier

John E. Johnson, Jr.

Anthem's statement multi-channel power amplifiers are called the P series. They come in two versions, a five-channel (P5) and a two-channel (P2). My home theater test lab has a 200 watt x 5 amplifier which works great for the majority of applications, but it is driving electrostatic speakers (ESLs), and for a handful of Blu-ray movies, the amplifier will go into protect mode when at high volume, because ESLs typically have a very low impedance (1 ohm) in the high frequency range.
