Hey all, I'm looking for a not too expensive (under 1k$ - hopefully less) amp that I can use as a reference for tuning headphones. I'm looking for something that if I tune a headphone to sound right and good with, the headphones will sound right on the most number of other systems possible. So the most correct FR and tonality. I can test dynamics and resolution with other amps, I'm mostly looking to check balance of mids, treble, bass and tone. The Gilmore cold, flat tonality doesn't work here. Nor the super warm Black Widow. So far I've got these on my list: Schiit Magni 3+ (best balance and tone of any solid state amp I've heard) Cavalli Liquid Carbon X Cavalli Liquid Gold Wondering if an iFI Micro Signature or Diablo would be good. The Micro BL sounded very "right" to me but it's been a while and I don't know if the Diablo has that character. Any recommendations would be great! I want to try to figure out what is correct and how my current amps are colored and affecting how I tune headphones. I don't currently use any measurements to tune, it's all by ear so the gear I use is pretty important. I know, maybe I should invest in EARS instead, but I'm no computer wizard and it all looks like a nightmare. And I dont' think I would trust the results anyways. I only really trust Marv's measurements on this site. Because I've compared them to my own impressions of headphones for years and they match exactly.
