Today I rolled in a new and matched pair of Gold Lion 6922s and a new pair of matched Novosibirsk 6H6p into the Valhalla 2.
After letting Valhalla 2 warm up and stabilize, I gave it a spin with the HD600. This is a definite improvement over the stock tubes.
This complement of tubes tames the slight upper midrange glare I was getting with stock tubes. The upper midrange and the treble region is silkier and smoother.
I'd say the Valhalla 2 has finally locked in with the HD600 cans where I would expect an OTL and HD600/650 to be
Still not at the magic level where the Brocksieper EarMax was with Telefunken triodes but not that far behind now with the midrange magic. On the other hand, the Valhalla 2 is more open, dynamic and resolving while almost matching the EarMax in the tube midrange magic.
Have not noticed any significant changes with bass but will keep listening.
Much of the tube magic is back with the Gold Lions.
