I have had many Hegel amps in my store. H70, H100, H200, H20, H30. They have never failed to impress me (and I'm not easily impressed). I was lucky enough to have a pair of H30 monoblocks for a couple of months and I couldn't stop listening to them: seeminly unlimited power and bass extension, but also delicate finesse in the critical upper midrange. I currently have the H20 and--though not as powerful as the H30--it still rivals anything else I have in its ability to produce beautifully detailed imaging, strikingly sudden (but natural) transients, and a deep soundstage. Even the H70 integrated is a personal favorite of mine: it sounds much better than a $2000 integrated should. It's hard to properly describe, but when auditioned side-by-side with other brands, Hegel amps just tend to sound more "compelling": that is, they grip you and make you listen... deeply.
