I have never owned a DAP/Amp, but with my purchase of good IEM's, suddenly an amp with player seems appropriate. The trend seems to be on Amazon $37.99 or $3,799.99. Thimble or 55 gallon drum. I'm not really an audiophile, I'm a pro audio guy, recording engineer and have always sort of felt that high end amps and monitors are not reminiscent of what the end user will experience in their cars or with their skull candy earbuds, so it may be doing them a disservice for me to mixdown on really high end gear. I choose Mackie Powered monitors or Sennheiser studio monitor phones. Well... now I've got some really high end IEM's, ear impression at the hearing aid place and everything. I'm driving them with my Samsung galaxy when I'm not at my Midas DWS (which has ADDA converters and Onyx preamps so good you'd poop, and they're finalized with six Presonus Tubes) and it's just... sad to run them on a cell phone. Community!!!! Any finger pointing or snickering at my dilemma aside, help me out!! I want this to run off of Micro SD and preferably rechargeable internal battery.
