power amp recommendation

I am using a Naim Superuniti [80 watts per channel] to drive a pair of YG Carmels. Wish to upgrade the amp side. I am considering the Hypex Ncore 500 class D amp; any other solid state recommendations? Thanks

It looks like the speaker can be driven by tubes as well.

I would look into Pass Labs if you are thinking solid state.
Pass amps have blue meters on the front and sound real good. So maybe that's a "win win."  Tubes are more fun though…but everyone knows that...
Since you are open to Class D and depending on your price range, check out Wyred4Sound.  I own the ST500, and after having owned older power amps from Marantz, Parasound and McCormack,  I could not be more pleased.
