It has a really smooth and unintrusive bass boost. They helped balance out my Ety ER6 back when I had them. The "wide sound stage" switch, which is basically some kind of crossfeed, I think, is also welcome on really channel separated older recordings.
(I don't mean to jump in, but as someone who uses a very similar setup to yourself with similar experience, I figured I'd be useful here.)
You should also keep in mind that I haven't heard a "better" amp than this, really. I'm sure I'll dump on it later when I have a SuperMicro or something. Curse you Head-Fi!
