I think if either of you heard the battery powered SB2 or EA Off Ramp, youd be very impressed with the sound quality.
I have the Redwine battery powered USB Select and am completely blown away with it.
Steven, I'm not sure how much cleaner and clearer it could get with a battery fed Turbo Off Ramp, but I suspect that the (foobar) upsampler and maybe the EA modded P3a is the limitation on my system now.
The EA modded 7700 is very impressive to begin with, so the fact that the Off Ramp clearly beat it should mean I am impressed...The difference is not subtle, you don't have to strain to hear the difference, but I didn't see God either, and didn't want to give that impression. I should also say I've been listening to 24/96 for a long time now with the Perp Tech P1a doing the upsampling.
I think that Steve has another mod for the P3a, otherwise mines pretty up to date.
If you went from 16/44.1 to computer based 24/96, I can see why you were blown away.
