A 20 watt stereo tube amp that is bridgeable to 40 watts into a single channel, the $2100 Bob Carver Black Magic 20 is sure to turn heads. We love the look of the amp and the pedigree of the manufacturer can't be denied. While we have to hold our noses as we dig through all the audiophile psuedo-science and marketing speak, we're sure this is a quality offering. Now, if only we could get a review unit.

Almost everyone can appreciate having a whole-home audio system, but not everyone has a home that is wired for audio or the ability to wire it. The number of truly wireless multiroom systems is rather limited (SONOS and Aperion’s Zona are the only reliable products that come to mind). Now there is one more contender, and at about 1/5 the price of SONOS to boot! Best Buy has thrown their retail power behind a system called "Rocketboost". Rocketboost is a wireless platform that allows for uncompressed audio (48kHz, 16bit/24bit) distribution around the home. So far, Insignia (Best Buy's house brand), Rocketfish, and Onkyo are supporting Rocketboost technology. They currently offer it in a pair of headphones, an outdoor speaker, soundbar, subwoofer, powered bookshelf speakers, a TV… you get the idea. It is a pretty laudable goal to attempt to unify the audio throughout someone’s home, but many wireless systems have major flaws. Range, sound quality, operability, expansion potential, etc., and these things can make or break a wireless format.

The Master TVA30 is a great option for someone looking for an economical, non-commercial guitar amp that provides great performance and useful options. The amp head appears to be built very well and is fully capable of performing better than anything in its price class. Though I pointed out some mechanical shortcomings, these do not take away from the overall tone and performance of the amp. For the price, it’s nice to see two channels, one for clean and one for over drive, and an effects loop. The system also comes with a two button foot controller to help you switch between channels with ease. When considering that it retails for $869, there are very little options that can compete. Though, if you are an audio fanatic like me, it may be worth springing anywhere some extra coin on a better speaker driver and tubes which I discuss in this review. I’ve found U.S. Masters pricing competitive and their level of technical understanding to be far better than other on-line stores or guitar centers. Even if you perform some upgrades to theTVA30, you’re still only around $1,000 for a great combo that is portable and very well made.

While we're not sure how well the Statement M1 will sell, it certainly looks good on paper. Given the 2000 watts of power with a highly efficient Class D design, it certainly will turn heads. Anthem set an impressive list of design goals for themselves and they believe they've achieved them. If so, you may be looking at an amp that will require much less space, can be stacked, outputs more power with less heat, is stable into any load, and sounds as good as any analogue amp. Is that worth $3500 per channel? We're guessing to many high-end users, it is.

ELAN was at the Hilton today, unveiling its new S1616A, a 16-channel multi-zone amplifier/controller that combines the functionality of the ELAN D16 amplifier and S128P multi-zone controller into one new component. It's pretty cool and should simplify installations and lower the total cost for dealers and their clients. The new ELAN S1616A Amplifier/Controller, which is designed to integrate exclusively with the ELAN g! System, will be available for delivery in the United States this month (January 2012) for $3600. The new ELAN S1616A is available in single- and dual-chassis versions, both of which include high-pass and low-pass crossovers, RCA inputs, speaker level and banana plug outputs, and feature level, bass and treble adjustment for each output channel.

McIntosh popped out a new 50th Anniversary edition of its popular MC275 tube amplifier. This edition features the same great quality of the MC275, but also comes in an elegant gold-toned chassis. As we learned with teh now all-but-extinct 100th Anniversary Edition Denon products, the specially created amp is being offered in a very limited quantity. The amp will come with a commemorative history book and deluxe packaging. But that's not all the 50th Anniversary Edition delivers, there are some other improvements as well. First off, the Limited Edition MC275 comes with a gold-toned chassis and features the classic 1961 tube circuit design of the original, but there are "under-the-hood" improvements as well. The 50th Anniversary Limited Edition McIntosh MC275 tube power amplifier is available from authorized McIntosh dealers for a suggested retail price of $6,500.

Bel Canto asks the question: Why choose different components for your music downloads, computer, CD player, turntables, cable/satellite box or game consoles? Their answer is to "keep things simple" with Bel Canto's compact, powerful C7R Receiver! The C7R, which is more like an integrated amp, tuner, and DAC all rolled into one, is loaded with inputs including two 24/192 SPDIF, two 24/192 TOSLINK, and one 24/96 USB, MM Phono and Analog Line Level inputs. Output connections are via upgraded WBT NEXTGEN Speaker Connectors plus RCA Line Out and a Headphone Output.

Simaudio introduced the Moon 810LP Phono Preamplifier at the Venetian, their latest addition to the Evolution Series of audio components. The 810LP features a dual-mono fully balanced differential design, and represents the company's “all out assault” on phono preamplification. They describe the preamp as an "ultra-refined audio circuit" which they have mounted on top of a floating suspension. As with many audiophile products, the Moon 810LP is also highly configurable, with selectable gain, impedance loading, capacitance loading and equalization curves. These can all be tweaked using DIP switches located on the bottom of the device. The goal is to make sure the Moon 810LP works with, and more importantly - sounds good with - virtually any available phono cartridge on the market.

Pass Labs busted out their new Xs-300 and Xs–150 Amplifiers at the Venetian to tickle the ears of audiophiles and amateurs alike. These are actually just the first entries in what is slated to be a new generation of Xs Series amplifiers. CES is a great place to do this as it affords, in the Venetian at least, a great place to sit and listen and take in the full experience of what a $65,000 or $85,000 amplifier can, hopefully, do. Made out of billet gold and platinum... just kidding... The new Pass Labs amplifiers are designed to measure well objectively. But they are also designed to perform subjectively as well as they measure. Pass Labs claims their new enhancements further narrow the gap between what scientific measurements report about amplifier performance and what the human ear subjectively hears. That's pretty cool - and for the asking price we'd expect nothing less.

When the Denon PMA-A100 was announced it would be part of their 100th anniversary product line-up, we asked for it. And we had high expectations. Turns out Denon met our expectations and even blew by them in some areas. The A100 is a stereo amp that weighs nearly 57 pounds and even has cast iron feet. There are also hardly any lights on the front of the unit, making it a truly audiophile product - with nothing wasted on unnecessary displays or LED status lights. The PMA-A100 produced some of the cleanest measurements on our test bench that we've ever seen. Great looks, great performance, its truly a statement piece worthy of the Denon name. It's not often we get the chance to review an integrated amplifier from Denon. This is a high-end product from a company who we've determined in the past REALLY knows how to make good amps.

The Sherbourn PA 7-350 is a beast of an amp. With a massive 3.3 kVA toroidal power supply pushing 350 watts into 8 ohms, 4 ohm stability, and seven channels of amplification, the PA 7-350 is a monster. At over 100 pounds and with convection cooling and a high efficiency, “Soft Switch” class H design, this truly is an audiophile-grade amplifier. If you define "audiophile-grade" as "tons of power, every feature you'll need and none you don't." If you define it as "full of silver/platinum/chocolatey bits, marketing speak, and pseudo-science," well, you're looking at the wrong company. This should be an amp that custom installers will love to get their hands on.

Our only real complaint against the Emotiva mini-X a-100 Stereo Flex Amp is the number of inputs. With only one, this integrated amp is a little hamstrung. But with it being rated down to 4 ohms, and with 60 watts at 8 ohms, this looks to be the perfect amp for the discerning Audioholic with difficult to drive speakers for their office, bedroom, or outdoor area. At $200, it is the perfect amp for a Zone 2/3/4 situation where it will be fed from a receiver or processor. If you've been looking for a solution for your Zone 2 woes, or perhaps just want to do something with those extra speakers, the Emotiva mini-X a-100 Stereo Flex Amp may be just what you were looking for.

What is a small amp for your office that allows you to connect not only your computer but three additional sources worth? Our minor complaints aside, the Orb Audio Booster Mini Amplifier looks to be a dynamite little product. We're dying to get one on our test bench to see how it holds up. We're constantly looking for good recommendations for office setups and the Booster Mini Amp looks to fit the bill nicely.

Pass Laboratories introduced its new 3-chassis XP-30 Preamp, the flagship to its XP line or preamplifiers. The triple-chassis structure allows the XP-30 to function as a modular preamplifier consisting of a power supply and control chassis and two additional gain chassis, each of which serves one channel. The XP-30 is typically supplied as a two-channel product but it's modular design means that it can be configured to serve anywhere from one to six channels. In this way it can serve the needs of a stereo or multi-channel system. The XP-30 joins Pass Labs' XP-10, XP-15, XP-20 and XP-25 in its XP series of preamps and phono preamps.
