I just bought an amp for the Hifiman HE-500 so i decided to go with the Schiit Lyr as i heard that it would be a good amp for HE-500. Man was i ever farther from the truth, my experience with the l yr has been total and utter ****, no pun intended. The amp constantly gives out a static feedback with high pitch squels that get really loud, apex then fade away as well almost a farting sound, plus the GE stock tubes are insanely microphonic. I honestly say i can't listen to this amp without getting a headache from the feedback it produces. This was my first venture into high quality amps but damn i really don't like this thing, after dropping the money on it i feel cheated, is this how all tubes amps are or what? I can't listen to anything that doesn't have a total wall of sound thrown at my without hearing some kind of pop, squeal, or buzz. I wanted to get to sound nirvana, let the music take over so i figured this be the way to do it. Is there anyway to fix this Lyr or is this how they all are, if not whats a good alternative to it for the HE-500 preferably under $350 and probably solid state as tube amps tend to be really fussy.
