@charles1dad -Thanks for the kind words. I have an ARC 28SE, ARC 75SE and ProAc 30R speakers. I put together my system because it makes the jazz music I listen to sound fabulous.
I'll certainly share my impressions. And yes, what people have said about the DAC is correct.
I've read about the wall wart power supply and the outboard power supply upgrade. That's down the road.
