I ran a pair of PSB Stratus Gold i's with my Conrad Johnson LP260M-SE amps. It sounded great. The LP260's use 8 KT120's per amp. I was then able to upgrade to Conrad Johnson ART300 amps and Egglestonworks Viginti speakers. The ART300's use 4 kt150's per amp. I am pretty sure this is my forever set-up, or at least until my kids are done with college.
I have seen a couple of people knock high powered tube amps. That may be their experience. My experience is that I have had great results with both CJ tube amps and both the PSB's and the Egglestonworks.
Happy New Year. Enjoy the music.
