What would be a better buy?

Not sure of Dennon, but Unico I've heard with efficient Triangle speakers and I think it's not even close to 80Wpc.

Yeah, I've heard that Unison Research don't rate their wattages conservatively. I really don't know about the Denon, but I've never heard people saying anything bad about it given its price. I just might go with the Denon

I just ran my Proac 3.8's with a UNICO. I beg to differ on the responses posted here. It is an EXCELLENT value period. It made my Classe 15 sound poor. It held it's own against an Ayre V5x and it made me want to quickly hook up the ARC D250 to make sure I wasn't doing the wrong thing by buying the ARC.
YES it is NOT as good as the aformentioned amps but it DOES offer 80-90 percent of the sound.
I should mention that I also have installed RCA cleartops from Andy at Vintage Tube Services and it is imparative to move the jumpers and take the output protection circuit out of the way!!!
I was going to sell this to help pay for the D250 tube giant but I am really thinking of keeping it for a rainy day. It is THAT good.

...as well as Classe that is simply unable to bring up the might...
way too soft just like UNICO.

Do some research on Rotel separates and you get even more than you expect for the bucks you're about to spend...
