Amp for Yamaha Soavo 2

Dear HiFi Gurus:

I playing with a second system. I have a great set of speaker to base it on: Yamaha Soavo 2. But I'm afraid the Integra 50.3 I'm using is not bringing the best out of them. To be fair, the sound is incredibly sweet, but it lacks a bit the impact and edge.

Any suggestions?

Have you got an amp that plays really well with the Soavos? Or an amp that is more sharp/clinical/lean to balance their incredible sweetness?

I'm considering both integrated and power amps. Digital input is a plus, but not a requirement.

Cost is also a factor (that's a second system after all :-). I'd prefer to keep it below $300. Max $500.

Your advice is greatly appreciated!!

All the best,
Walfredo
