Don’t know the other amps but I can vouch for the Parasound A23. It is a real power amp. I was surprised when I first got it, I hooked it up to Dynaudio Focus 340s which are usually hooked up to a Simaudio power amp. The a23 had absolutely no problem dealing with the 340s, they just sang.
The a23 is now hooked up to Focus 160s on a different system. It is very musical and sounds great.
You will need a preamp though, since it not an integrated amp. Maybe your denon has a preamp out feature.
The a23 does run a little warm even if it is not active. I leave it on all the time. It needs a bit of space to breath.
If you are looking for a good inexpensive power amp, the a23 is exactly that. And its physical size is also impressive. Given what it can do, it is quite small.
