I'm not sure how much power you need but I have owned a bunch of tubed amps: Bat VK75se, Music Reference RM200, three from Art Audio, Cary V12-R to name a few. I purchased a Hovland Radia about a year and a half ago and have not looked back. I use it with a Audio Research LS-26(tubed)pre amp and the sound to my ears is steller. I really like the SS amp and tubed preamp combo! It drives my Sonus Faber Cremona's with ease!!
