thinking to upgrade power amp to make B&W dm604 s3s sing. any thoughts on NAD s200 vs Adcom gfa 555II or GFA 5500? currently biamped with NAD c325bee driving mids and highs and Adcom gfa535II driving bass {using preamp section of c325bee}
Ive own 3 Adcom amps 5802 ,555 ,2535 . If you have speakers that are bright go with the 5500 . Dull speakers would benefit from the 555ii . Mosfets almost always sound better than bi-polar in my opinion.
