I drove my Sequels with a ML #23 and CAT SL1 Signature preamp. The system sounded very good indeed. Then I replaced the #23 with an ARC CL-60 and the sound became glorious. I also added a judicious bit of low end foundation with a Mirage BPS 400 sub. I suspect that short of getting a pair of Sound Lab A1 or A3s I am going to enjoy my present system for many years to come.Charlie
