The trailblazing staff at NAD just released all new top line stereo separates. The M12 preamp features a pure digital design with a modular case that is fully upgradeable for future signal formats or improved circuitry.
With their new, fully-digital integrated amplifier, the TDAI-2170, Lyngdorf Audio squarely targets the "iPod Generation" by taking the familiarity and ease of use oft associated with the ubiquitous portable player and combining it with true audiophile sound; all beautifully executed in a clean, sleek package.
The Yamaha MX-A5000 is an 11-channel, incredibly flexible, multi-channel amp from one of the most respected names in home audio. The MX-A5000 is capable of working with a dazzling array of set-up combinations, and produces competent and clean amplification for those with even the most complex of setups.
With the success of the Pass Labs Xs series, Nelson Pass set out to create a line of additional power amplifiers that have most of what the Xs series has, but at much more affordable prices. The model under current review is the X600.8, which is a monoblock specified at 600 watts RMS output, with the first 50 watts in Pure Class A, and the rest in AB. Do they sound close to the Xs amplifiers? Read on.
The Audio by Van Alstine FET Valve CF Vacuum Tube preamplifier is a pure analog design with no solid state transistors in the signal path. It is based on a Cathode Follower architecture providing wide bandwidth, substantial gain even into difficult loads.
Mark Levinson, one of the most respected names in audio, has just released their latest stereo preamplifier design, the No52. Its looks, handling, and performance are what you would expect from Levinson: Extraordinary.
Class D (i.e., "Switching") amplifiers have been around for quite a while now. What's clear from models produced so far is they all sound different, even when using the same core technology. Like many amplifiers of the type, the NewClear NC1000L uses the Bang and Olufsen ICEPower module. What makes the NC1000L different isn't this module; it's how that module is implemented. NewClear Audio was started by Sean Brady to improve upon the sound of existing switching amplifiers. Sean had heard some very good amps based on ICEPower technology, but thought he could do even better. The question is, does the NC1000L deliver the goods compared to similarly priced, traditional Class A/B amplifiers?
The Emotiva XPA-1 Gen2 is an update to Emotiva's 1,000 watt per channel monoblock amplifier. There are subtle improvements, from a higher quality RCA jack and electrical changes, but the most noticeable is a switch up front. It allows the XPA-1 to run in Class A for the first 60 watts of power.
The S-550i is the larger of two new integrated amps from Krell. Both of these amps feature circuit boards that utilize surface mount components. This means they can pack more power into smaller chassis than ever before. The S-550i is rated at 275 watts per channel into 8 ohms, and that doubles to 550 wpc into a 4 ohm load. This being from a box that is less than 6 inches tall. So now you can get tons of Krell goodness in a small package and at a very affordable price.
