I used a Krell KAV 250a amp with Hales Concept 3's and found the sound a little too aggressive and bright. I had much better success using Balanced Audio Technology VK 200 with the Concept 3's. In fact, I still use the BAT with my Hales Transcendence 5's (similar sound to Revelations). If you decide to go with Krell I would avoid the KAV line and go with a FPB.
Krell amplifier with Hales speakers?
I was wondering if anyone could shed some light on they synergy of my system concerning the amplification. My current system consists of a Well Tempered turntable, Acoustech ph-1p phono stage, and Krell KAV 250cd front ends, these feeding a Krell KAV 300i integrated amplifier. I have all Audioquest ruby interconnects, and Audioquest type 6 speaker cables. My speakers are Hales Revelation Threes. I am wanting to upgrade my preamp/amplifier, should I go with seperates? I am looking at a Krell krc 3 preamp, and either Krell monoblocks (kma 100) or Ksa 150 amplifier.
