No that isn't it at all. The PSU is basically a toroid with 4 seperate 15-0-15 secondaries, designed to drive up to 4 discrete devices, including DAC's, Headphone amps, MC head amps etc. Each device comes with a cheap & cheerful wall-wart style PSU. The x-PSU is an optional upgrade that replaces up to 4 wall-warts. I only use 2 of the outputs. The AC is rectified/regulated inside the devices. The cooking linear regs have been replaced by super-regs in my units. Using discrete PSU's means that common-mode + ground plane noise is kept to a minimum. -- Phil Leigh You want to see the signal path BEFORE it gets onto a CD/vinyl...it ain't what you'd call minimal...
