I had four pairs of CLS's and a number of different amps. They love tubes like any of the ARC amps and they really love Pass Aleph 2's. The key with CLS's is to get the bass off of the panels by using a subwoofer below 90Hz so that there will be less IM distortion.
depends on ur $..to handle the load and the push ...high powered VTL...or get high powered solid state...classe, bryston or Mcintosh above 250 RMS/ch or 5802 adcom .. with tube pre amp.. U also probably need a pair of tight subwoofer ..short well define 'hit' with 8 to 10 inches woofer
I have a pair of CLS II's (older model = tougher load) and plan to drive them with a Krell KSA 300S and a tubed pre. I have talked to many and all agree this amp is a perfect mate. I have heard this combo and the synergy is great.
I just talked to my buddy Tony at Hi-Fi exchange and he has a pair of amps that will go well with the Logans.Fourrier Sans Pariels.Monster amps like the Futtermans,He can obtain the Futtermans also if you desire.Call him at 718-767-9379. Mention steve sent you..
