First post here Question is in title. I have heard the UE 600's have great sound but lack a bit of bass (still very present just not what they're "praised" for) and I have seen that the e5 and e6 amps offer bass boosting and sound quality as a whole. Problem is, some say the e5 has better bass boost, but the e6 is a bit muddier in that bass boost department but offer less hiss as well. Can someone help me decide which Amp to purchase? Thanks!
