I am looking for an dac/amp to go with my HTC one x on the road and to use at work behind the PC via USB.
While the E18 seems like the perfect match for my phone:
usb dac from android (would that make a big difference compared to only using the AMP part of the e17?)
charging my phone
more powerfull (both battery and amp power)
it has some drawback compared to the e17:
no (decent) bass/treble adjustment
no spdif input
less good sound quality/interference from phone/bass boost humm/USB OTG cable disconnecting/dying etc
While I think the fist differences are very personal (italics), as in, what do you need most (although any insights in the usefulness of those functions would be appreciated as well).
My major question comes from that underlined last part. As I read most of these SQ problems in this thread or on other threads on this ocean of information called Head-fi, I hope you can provide some extra insight. How bad is it? I am a beginning audiophile, owning an K612 pro and having a decent sound system at home, so I am not THAT picky. I love the K612 on my marantz receiver, but my phone and pc at work severely lack the power and precison to drive the cans.
Do you think I will notice the sound quality and interference problems on the E18?, or is that something for the hardcore audiophiles. And how about the E17, does it have comparable problems? I did not read any problems with the (usb) connection failing during traveling on the E17. I have read ~ 50 pages of both this thread and ~40 of the 433 pages long E17 thread, and while both have some negative reviews, the E18 seems to have slightly worse reviews. I know it is hard to advice somebody else on this kind of thing, but any insight would be greatly appreciated!
One more question: I am in doubt about buying a second hand one. How is the durability of the battery on Fiio products? Would be a bummer if I get one with a dying battery.
