Ah, I wish I could tell you about the DBA-02, but I don't actually have them yet...I've emailed Budgen Audio to see about availability and they have to get back to me. It sounds like the perfect IEM for my needs though, and they've gotten high praise from others around here. So, still waiting on them, but I'll let you know how they are when I get them.
Second, nice review, makes a lot of sense...I think every amp takes time to burn in, so hopefully it opens up a bit more in a few hundred hours. I'm sort of in the camp that the headphones are the most important part of your setup (that and source/files), followed by amps and such, so I don't really expect a 50% increase in SQ or anything, if it was even a measurable quality. I'm considering a few amps, solder_monkey and MisterX Mini3, the Corda Headsix (if I can find it for $160 or so)...
I'm trying to upgrade my entire portable audio setup, so supposing I get the Fischer DBA-02 at $160, the DIYMOD for $150 (don't actually know how to do it myself), and an amp, I'm looking at $500 or so...saving money anywhere along the line would be good. Actually considering skipping the DIYMOD for now, and just using the Clip+/Fuze until I can save a little more...
Thanks a lot for the review, hope the amp opens up even more for you, I'll let you know how the DBA-02 sound when I get them!
