Has anyone else had a problem with subdued bass from the Valhalla? I was quite disapointed when I first started listening and realized that the bass response was so weak (the shrill painfully piercing highs in some of the Classical stuff that I listen to were not missed quite as much). After hooking up an equalizer, it became aparent that the problem was not a lack of bass but excessive mid-range drowing the bass out. Dropping the mids a notch brought everything to correct ballance, but the sound coming out lost its crisp clarity and became muddy.
The amp has about 100 hours on it and I'm listening to dt880 600's (the Beyers have excellent bass response from every other amp I own).
Will the tubes calm down and become more ballanced with more burn in, would tube rolling fix the problem (I know Schiit advises against it), or do I need to spend money on a quality equalizer with a crap load of bands that will allow me to attack the the offending frequency with more accuracy?
