For the 2-CHerry specifically:
The 2-Cherry has a 1000W+ power supply driving both channels, and power is only consumed by each channel as needed. This amp has channel independent auto-sleep. When an input is "quiet" for more than 8 minutes, the corresponding channel automatically sleeps, so you never need to turn the amp off. The channels wake up immediately when audio returns.
Both 2-CHerry channels are capable of 400W into 4Ω. THD+N is 0.002%, and SNR is 118dB. Bandwidth is 100kHz. Output impedance is 0.016Ω wide-band. All x-Cherry amps (2-CHerry, 3-CHerry, 4-CHerry, and 5-CHerry) are DC coupled and true balanced end-to-end. The design is tweaked for sound quality above all else. The design philosophy is simple: sonic transparency. The 2-CHerry is also compact and lightweight (14" x 9" x 5", <12 lbs).
