A tip on tips (pun intended):
I don't know if anyone else has tried this combination, but I'm loving Sony Hybrid tips with the DBA. Obviously, you'll need to use spacers like the ones that come with the Monster Supertips, but medium-sized hybrids are a great fit ---- when pushed all the way to the hilt, the tips don't extend beyond the plastic sound tubes of the DBA, lessening the acoustic effects of the silicone core of the hybrids and retaining the DBA's great clarity, but obviously you still get the great comfort of the Sonys. As many of you know, hybrids also help greatly with consolidating the bass, which helps with the DBA's tonal balance IMO. Detailing takes a little bit of a hit, but it's not really a big deal, considering the added benefit of sonic cohesiveness. Eight months after I bought my DBAs, I've never enjoyed them more, thanks to the hybrids.
So, the bottom line is, if you have Sony hybrids or hybrid clones, try using them with the DBA (provided you have the proper spacers).
Oh, and I know hybrid-like tips come with the DBA, but I never got along well with them. The core sound tubes with them are much taller, and thus occlude the sound more than real hybrids. They're also not nearly as comfortable as authentic hybrids.
