Hi! I have a question that's not 100% related to recording, but here goes anyway: I wan't to get a set of open or semi-open headphones to use for mixing and hifi use. They have to be beyerdynamic, as I can get those heavily discounted, but can therefore be expensive What would you go for? DT-1990 or would DT-880 or 990 "do it"? The price difference is quite big... Now for the other question: I need a digital and analog headphoneamp for my stereo. Must have digital coax and analog rca inputs, and ideally also "throughputs" for those. USB would be nice, but not essential. What available and good here? Cheers!
