Thinking of pulling the trigger on Amazon's DT990/E5 combo for $299.99, but I have a few questions:
1. Maybe I'm missing something, but the line/optical out jack-does that only accept a toslink, or can I use a regular 3.5mm jack (I need line-level audio to my Klipsch Promedia's, which uses a 3.5mm male plug). This is kind of a deal breaker for me if the E5 can't accommodate an analog line out. I currently own an Fiio E10K, and it has a handy-dandy 3.5mm line out.
2. Since Creative won't or can't tell us power specs, I'm assuming the E5 is powerful enough to drive the DT990's (250 ohm version)? I have found, upon borrowing a friend's DT990's, that the E10K can't drive them sufficiently.
3. This will be used exclusively as a desktop amp. Any issues from having a constantly charging battery in the mix? (Obviously I'm using the micro USB to connect to my computer).
I know power isn't everything with amps, but this particular amp seems to check off a lot of boxes for me (power, using different sound profiles for different headphones, small form factor, a company that stays on top of firmware updates). I'm coming from the Fiio E10K, which has served me well over the years, but I keep having to replace it because of various issues. Plus, this Amazon deal seems pretty good. I really love the DT990's (250ohm) "fun" sound and extreme comfort, plus I think the E5 will serve the other headphones I have well (PortaPros, ATH-M50's, XB-700's, Denon AH-D1100's).
I was eyeing the O2+ODAC, and Schiit stacks, but this amp seems more flexible, and of course that Amazon price!
