Ayre MX-R TWENTY

Stereophile found that the amplifiers maximized the audible differences among individual pianos, a strong indication of low coloration and high resolving ability. The reviewer says they stepped out of the way of the music, letting it flow unimpeded.

The review's description of music flowing freely points to a natural, musically communicative presentation rather than an overtly mechanical or imposed amplifier character. Its ability to preserve the individual sound of different pianos also suggests convincing tonal differentiation.

Stereophile does not directly discuss bass slam, transient attack, or compression on demanding peaks. Still, the amplifier was described as getting out of the music's way and allowing it to flow unimpeded, with no indication of restraint or strain; its specified 300W into 8 ohms and 600W into 4 ohms support substantial power reserves.

The review does not offer direct observations about stage width, depth, image focus, or layering. However, it found the MX-R Twenty highly effective for evaluating loudspeakers because each model sounded more like itself and more distinct from the others, indicating very low obscuring influence on a system's presentation.

The MX-R Twenty is a fully balanced, discrete-device, zero-loop-feedback monoblock design. Ayre's Double Diamond output stage was specifically developed to reduce the high operating temperature associated with the original circuit, while the specified 300W/600W output indicates serious power-supply and output-stage execution.

At roughly $24,000-$25,000 per pair, the MX-R Twenty sits firmly in the premium monoblock market. The available review is highly favorable about its transparency and usefulness in revealing loudspeaker differences, but it does not compare its price or value directly with competing amplifiers.
