I'm having so much trouble choosing a dac/amp!!! its literally killing me! for now i'll be powering my beyerdynamic dt770 600 ohm headphones but eventually i hope to just hook the dac into my integrated amp to power some speakers. I can't decide if i should get an integrated dac and headphone amp or just get them seperately. If i go the integrated route i was thinking about doing a yulong d100 or the nuforce icon hd, however i heard the nuforce makes the beyer's super harsh with highs. if i go the seperate route i was thinking the HRT II+ music streamer and a matrix M stage. Help Please
