Well I've had my DBA-02 for more than a month now and I love it. I've previously owned to RE0 and used it unamped and always thought it was good, but the DBA is a total step up for me. The treble is slightly better on the RE0, but that's no slight against the DBA because it sounds fantastic in this aspect too. It's just that the RE0 is godlike when it comes to the highs.

The DBA beats the RE0 in everything else. It is a lot more exciting and involving. The bass for me is punchy and sounds very nice, although I'm no basshead. The soundstage is much wider than the RE0, and it feels so airy! The depth and imaging are excellent, it's like the whole soundspace is filled with real air and instruments playing around and in your head.

So if you are looking for something that's crisp and fun, I wholly recommend the DBA-02. But the said soundstage, depth and airiness will only be found if you manage to insert it deep.

No I havent heard the Eterna.

I'm actually selling my RE0, PM me if you're interested lol.

But the RE0 really isnt for bassheads. There is not much weight to its low end and you wont be getting much impact... but I've never amped it. Treble and clarity is spectacular though.

Lol that guy would be ClieOS. I think he gave the same award to the DBA as well.

Did you sell it to a guy here called blegh?

Haha coz he offered to trade it with my RE0 because he found it too bassy with very little mids and highs, and I very much doubt I will like it so I declined.

I dont care for amps since it defeats the very purpose of portability.

I do encounter a little sibilance from time to time on my DBAs, but it's nothing that vexes me too much. And it's only on certain recordings so it may be the source. I get excellent seal and comfort from the stock single flange tips, and the only complaint I have is that the tips do not grip the nozzle well enough and sometimes the tips get stuck in my ears.

As far as I'm concerned, when compared to an unamped RE0, the DBA absolutely blows it out of the water. It has much better mids and bass, imaging and separation, and soundstage.

Of course, a sufficiently amped RE0 may well beat it, but I wouldn't know.
