Yes, the Yamaha is adequate.

100 W + 100 W (8 ohms, 20 Hz-20 kHz, 0.019% THD)

But......

You should be looking for 150W min. into 8 ohms and an amp that hits near 300W at 4Ohms if so. The Yammie does not and is not great even at 4ohms.... 160W at 1khz (I'm guessing burst.) It is an AVR....

BTW, in Canada Solen.ca is a good site to check out the Bryston line.

A used Classe Amp would be really nice.

A Cambridge Azur 851A would be nice too. https://www.cambridgeaudio.com/can/en/products/hi-fi/851/851a

Cambridge is kind of the everyday mans high end. Great value IMO.

The most dynamic 2.0 system I ever heard was a pair of mono Devialet class D 800W amps into Focal Sopras. Just nutty. and Nutty expensive.
