Hello all, I am considering my next amp purchase for my Sennheiser HD 650's and the Valhalla and Crack seem to be getting good reviews. Anyone tried both with the 650's? I don't care that the Crack kit is less expensive, I'm just curious to which one might sound better with the 650's.
I know you can tube roll the crack so that may be an advantage although I prefer the looks of the Valhalla but the stock tubes are pretty much their limitation from what I understand.
My source so far is FLAC > Monitor 02US...
