Aric Audio Systems Unlimited Preamp

A review of my Transcend KT88/120 amplifier just went up on Home Theater Review today.

Great review. Sounds like an awesome piece of audio gear.
Regarding the Motherlode preamp, given its “cost no object” design premise, my only suggestion is if a more sophisticated source selector option could be explored. I don’t know how much it may add to the cost or the design complexity but something like a relay actuated input selector would definitely make this preamp a world class contender. 

Thanks! As far as relay-activated- that wouldn't be prudent to the design as it goes against the "completely hand-wired" and no solid state components in the signal path. Generally a relay is "PCB architecture". This has a manual switch, and the volume control is manual as well. A digital preamp, I could see a relay input selector on.
