Very cool. With a little passive pre it would make a great energy saving system. I'm interested. PM sent. Any thoughts on how to further upgrade or mod it?
Well, you could add more channels (outboard), as the power supply can deliver plenty of current. BTW, I have a couple more Class T boards available.
Speaking of a passive preamp and low power consumption, I have another one of these--different chassis, lesser-quality power supply, but same Class T boards. I put a stepped attenuator at the input, and I wired it up so that I can bypass the internal power supply and run the unit on a 24VDC battery supply. These Class T boards running on battery give a super low background noise. And using a good linear supply, you get a little better dynamics. So, a tradeoff.
