Thanks for the info! O2 is on the shortlist. I have also seen some older used high end amps for 200ish (little dot v, burson ha-160). Are older high end amps more transparent/superior to the o2?

I've joined the train! Just ordered a used pair. Currently using my 5.1 stereo amplifier and a xoanr u7 sound card. Although my bank account is a bit empty right now, what amps/dacs should I be looking out for? Is a o2 enough? I am also looking at getting a little dot mk2. It would be awesome if...
