I can only speak from personal experience - I have a CJ Premier 14 with Classe 200 and just installed Alpha-Core MI-2 speaker cables and the synergy is the best I've had. These cables really opened up my Thiel 3.6's, far exceeded my expectations. I was switching back and forth between MIT 750+ S3's and Kimber 8TC's. The improvement is one of the biggest upgrades I've ever made...
