I’m starting to get into this headphone thing and looking for a good amp. I can’t tell what headphones I’ll want to play with in the future. So I’m thinking about one, good, general purpose amp. Something that can have the juice to run orthodynamics, high efficiency headphones, and everything in between. Does such an amp exist? Or do you need 2 amps, essentially, to cover all the headphone bases? From my reading, I gather that the really high powered amps like a Lyr do great with orthodynamics. But then do not do well with high efficiency headphones- low level noise and such. Conversely, a good amp for most headphones will not have enough oomph for orthodynamics. My question is pretty general. But more specifically, I’m hoping to not go over $500 although I could if there was a good reason. No preference on tubes versus solid state because they each have their strengths. No DIY unless it can be built in less than a day due to an unfortunate lack of free time. Thanks!
