Hi Christmas is coming up and i'm really looking forward to getting my first quality headphones and becoming a audiophile! So basically I have decided on getting the Senn HD598 as my first headphones. I would be using these for gaming, Skype, movies, and especially music. I know that these headphones are bass heavy, and I wouldn't consider my self a bass head either; however, I think i'm looking for a amp/DAC that would help the bass a bit more while keeping the sound stage and good mid. Because i'm using these for multiple purposes, what do I need for these cans? Is a sound card my first priority for a multi-use purpose? What amp/dac combo should I get, with or without the soundcard? Is an Amp alone good for the Senns, or does a DAC make a big difference? Besides the headphones, I would put around a $150~ budget. Ive seen some things I want, but do not know much about it. The HIFIMAN - EF-2A look good. I know i'm leaving out a lot of information, so if you could please ask more questions to see what I actually need that I would be happy to answer ) Over all, I just want the HD598 and would like some affordable recommendations for a amp, amp/dac, or a sound card.
