Can I use the DAC with my iphone, if so how would it affect the sound, is there a bass boost button?
How about the e5 e6 e7 and pa2v2, how do they affect the sound, I would prefer it not too boost the mids anymore than the iphone does. I have a HD25-1 II, Shure se215, and M50 to be powered. I wouldn't mind if it helped open up the m50 soundstage, but my primary focus is the imrpovement in the hd25 with my iphone.
