Uniwaving, not Unidrowning
A different take on an integrated is the two-chassis 1000Wpc Uniwave Tek Digital Anaco 2 stereo amplifiers ($6800). The switch-mode power supply is in a separate chassis from the signal-carrying elements. That 1000Wpc rating, by the way, is at 4 ohms. Bandwidth is claimed to be 250kHz.
The Anaco 2 is the product of five years of R&D. It certainly looked like a finished product and was making very musical sounds through a pair of Chateau Reference Monitors (now a part of Uniwave). I listened to some Rubenstein Chopin while in the room and it sounded properly sorted.
If you're convinced that all SMPS amplifiers sound alike, this is the amplifier that might convince you otherwise.
