The three phase power supply is pure Ayre. There are three amplifiers, one for each phase. "Essentially, they are mini-MXRs," said Silberman. They are 120 degrees out of phase with one another, and we need to tune each one with a stethoscope to achieve absolute pitch stability. The result?

The Music Player has tons of inputs: USB2.0, iPod (with control and display), S/PDIF digital coaxial, TOSlink digital optical, LAN, W-LAn, and RS232 for update and control interface.

It exists; we saw it for ourselves! Wadia's $349 iTransport can take the digital signal out of an iPod before the DAC, outputting 16-bit/44.1khz resolution for uncompressed files—it doesn't upconvert lower-rez files like MP3s, but it does reformat them to 16/44.1, according to Wadia's John Schaffer.

"Recent advances in solid-state output devices and other components have opened up design possibilities never previously available," Audio Research's Terry Dorn explained. "And that led to our developing the Hybrid Drive HD220 stereo power amplifier ($8995)."
