I don't want to hijack the thread, but I wanted to chime in about the IDA-8 that I've had running since right when it came out - via USB from the computer then off to the Axiom Audio M3's in my desktop set-up.
This is such a beautiful sounding (and off-the charts value) amp that I will do whatever it takes to keep her in the system. It is great to also know that the service, if ever needed, is first-rate!
