An advanced version of that innovation, the Double Diamond output stage, along with Ayre's recently developed AyreLock voltage-regulator refinement, and a few other new refinements, have now been applied to Ayre's top-of-the-line power amplifier. In the time since the introduction of their original MX-R monoblock, for which Wes Phillips had high praise in Stereophile's April 2007 issue, Ayre Acoustics discovered the suitability to high-performance domestic audio of the half-century-old 'diamond' circuit configuration of bipolar transistors.

JVS described the sounds of CDs, SACDs, and digital files played through the MA8.2s as 'clean, clear, and neutral,' though he felt the sound was, at times, 'a bit more spare than I'm used to.' That said, the amp's speed earned from JVS special praise.

The amp, which uses a full 30dB of negative feedback, is specified as offering 600W of output power into 8 ohms according to AVM's Udo Besser, depending on loudspeaker impedance, up to 40W of that output will be in pure class-A. The solid-state, class-AB Ovation MA8.2 is a fully balanced, push-pull design whose output section uses 24 N-channel and 24 P-channel MOSFETs, each bank drawing power from its own 1000VA toroidal mains transformer. (If the Max goes completely tits up, it automatically disconnects itself from the mains supply.) Listening through Wilson Alexia speakers, JVS found the Maxes to sound darker and less colorful than his reference Pass Labs XA200.8 monoblocks, but noted the tightness with which they depicted bass-drum thwacksВ—and concluded that, 'if your preferences lean toward hard rock, driving jazz, or propulsive/explosive music of any genre, are must-hears.' JA observed that, apart from a very low input impedance on its balanced input, 'Audionet's Max performed very well on the test bench.'

Its MOSFET output stage draws from separate power supplies for its positive and negative swingsВ—there are also separate mains-transformer windings for positive and negative voltagesВ—and outputs 400W into 8 ohms, 700W into 4 ohms, or 1100W into 2 ohms.

All amplifiers are stereo models, except where designated.Дesigned and built in Germany, the solid-state, class-AB Max is based on what manufacturer Audionet refers to as Ultra-Linear-Amplifier (ULA) topology, developed for medical applications. Except where stated, output powers are not the specified powers but rather those we measured into an 8 ohm resistive load. Careful auditioning with your own loudspeakers is therefore essential. Nevertheless, even within each subclass, Class A amplifiers differ sufficiently in character that each will shine in an appropriate system. Editor's Note: Because of the disparity between typical tube and solid-state 'sounds,' we have split Class A for separate power amplifiers into two subclasses.
