Hi, I'm driving my CS3.6 with Krell FPB200 amps (400 watts on 4 ohms)and this really made the Thiel's get all the power they need.Not a hint of brightness or grain on the highs, the reason I mentioned this is because the CS3.6 will sound bright if underpowered and you'll know it right away. Given that they are very demanding speakers and sensitive with cabling,the flipside is they are very rewarding once you actually hit the right combinations. I'm using Acoustic Zen Satori speaker cables and Silver Reference IC's on them now (and Nordost quattro fil between CD and preamp). I used to use all AQ cabling (AQ Diamond and Clear SE)on them before which also sounded good but the AZ cables gave it a touch of sweetness and warmth.
