Sorry to go off-topic for a mo...
I see you have a Singlepower MPX3. I had one a few years back. did you get your's checked?
The MPX3 is a great amp providing you get someone in the know to look over the internals.
Big caps, high voltages can be scary...as some owners have attested...
I now have an Extreme Platinum which I can't part with....don't use it at the moment but I have plans...:)
I have yet to hear a Benchmark DAC (1 or 2)...bow long have you owned it?
