I'm jealous, never had much opportunity to get to audition much Hegel gear. I can really only speak about the H590 and I will admit, I wish it was mine. One thing about many amps or integrated's, some seem to either have a roll of in the top end, or seem a little bright, some seem weak on the bass and some have strong bass. Some seem to have a thin sounding midrange, while some have a nice thick rich midrange etc, etc. Yes a lot probably depends on it's gain structure. And while I might not be explaining it very clearly or accurately, the H590 just seemed (to me ) perfect on all accounts. It just seemed to have a near perfect rendition of the recording, while doing so with complete effortlessness. No thought of needing to add some bass or treble. Needless to say, as you can probably gather, i was very impressed. ( ok, now that I have done free advertising for Hegel

, send me a unit )
