It's bloody good!
Ive had mine a couple of weeks now. It has a powerful, open and explicit sound in my system.
As far as integrated amps, In the last year or so I've had Gryphon Diablo, Luxman L-590 AXII, Norma IPA140, Arcam A49, Naim Nova, Cambridge Audio Edge A and several more I'd need to try harder to remember.
To my tastes it doesn't give anything significant away to any of them and beats them each in different areas. The digital section seems particularly strong at its price point. Then again so does the amplification side tbh.
As ever this is entirely dependent on your system, tastes, and particularly speakers.
The speakers that I specifically bought this amp for have ceramic accuton drivers which give a full, thick and warm sound in my room. So I was looking for an amp to give them a kick up the bum current wise and open them out with a very clear presentation. As such the Denon seems to have slotted in as a bit of a Goldilocks amp in this context.
