I bought the AKG K812 headphones to plug straight into my Wavelength Proton USB DAC and the results are not impressive so far. I chose those headphones because they are supposed to sound great without a headphone amp. Now I'm thinking I may have to give up on that approach and buy a headphone amp after all. Maybe a set of HD800 headphones instead of the K812s.
I really like Red Wine Audio gear since it's battery-powered. Has anyone used their stuff with headphones? Can I use a regular stereo amp with headphones instead of an amp made specifically for headphones, and just buy a special headphone cable to connect to the RCA outputs? I don't need portability at all.
