I own the Hegel H390 and do love it, however I can’t say it’s perfect. It gives me probably 93% of what I’m looking for, specific I know. I wasn’t able to demo it against much, only the Michi X3 and for me it was better sounding. It has a very smooth sound, one that isn’t fatiguing and I can listen to it for hours straight. I listen to a wide range of music, and the only thing it lacks for me is energy during drum and bass or heavy metal. The smooth side of it seems to lose that 7% extra I’m looking for. Now I listen to loads of electronic music, and for everything else it is incredible, so it’s not a problem with electronic music, it’s that it doesn’t seem to do aggression well, that grab you by the neck punch you in the face. For all other music types I don’t want that, and it delivers vocals, instruments, and everything else with a muscular ease while remaining utterly balanced. I don’t know if my speakers are contributing to this (Spendor D7.2), or the room etc, but in my system this is what I have found. Therefore if you are after that massive slam, I’m not sure I can recommend the Hegel, but it does everything else wonderfully.
If anyone has a different experience I’d love to hear what speakers you use, Spendor are British and are known to be polite which is why it may not be the amp. Why the whole system setup is important, not one component!
