I'm getting recommendations for the new esoteric, I can dig up the model if you want. A hifi shop owner I've known a long time assures me modern dac's sound alike unless one's defective, that said I bought a $450 dac that has a half a dozen digital filters built in because the designer? said what measures best isn't what always sounds best? I know negative feedback sucked the dynamics out of those receivers back in the day for .0001% thd bragging rights, but would that even apply to modern dac's? I would also like to know when the big breakthru happened and all dacs became equal, because those early cd players were awful.
