The MX-R TWENTY is a mono power amplifier from Ayre Acoustics, a well-established American manufacturer known for considered zero-feedback amplifier engineering, built with an extraordinary input impedance and remarkable power efficiency. The MX-R TWENTY brings Ayre's most accomplished current engineering to dedicated monoblock power amplification.
Key specs that matter
Input impedance is an extraordinary 2,000,000 ohms balanced - a remarkable figure ensuring minimal loading on any connected preamplifier. Output power is a substantial 300W into 8 ohms, doubling cleanly to 600W into 4 ohms - a textbook power doubling indicating a robust, well-regulated power supply. Gain is 26dBu. Frequency response extends to an extraordinary 250,000Hz within plus-or-minus 3dB. Maximum power consumption is a modest 120W - a remarkably efficient figure relative to the 300W output. At 280 x 480 x 95mm and 23kg, the MX-R TWENTY maintains a manageable monoblock chassis for its substantial output capability.
Sound and use context
Expect substantial power delivery combined with exceptionally clean, efficient amplification reflecting the clean power doubling into 4 ohms and remarkable power efficiency, consistent with Ayre's broader considered zero-feedback engineering philosophy.
Pairing
The extraordinary 2,000,000-ohm input impedance ensures minimal loading on virtually any preamplifier, and the clean power doubling into 4 ohms suits a wide range of loudspeaker impedances.
Alternatives
Ayre's broader amplifier catalogue offers alternatives for buyers wanting a different output level.
