Ok, here is something i though would be a no-brainer...Which it almost is,, but now i thought it would be...David vs. Goliath:
David represented by my portable rig, which was to be sold to afford Goliath: Optical into iBasso DB2, balanced 24bit/192 into iBasso PB2 balanced SS amp. Both setups drove a Denon D7000 though single ended outs (meaning the PB2 has even more to give on the Balanced). And so far, I have been unable to tell which sounds the best...Both has about the same sounstaging, SQ in general, the only difference is the very slightly more "rounded" sound of the Argon's tube. I am absolutely dumbfounded. I knew the PB2 had reputation for Desktop SQ, but i didn'r really believe it...Until i now actually have a desktop setup to compare it to. Any thoughts?
