advice for interconnects & spkr wires

I had a similar system last year with Acoustat hybrids (like your ML's) and a Bryston 4B-ST amp. At the time I was using a Bryston BP-25 preamp and decided to try out Puresilversound silver IC's, which by the way have great reviews at Audioreview.com. With a mid-fi NAD C540 cdp it all sounded too bright for me and never really settled down. After over 100 hours it still sounded the same. This may have come from many reasons/issues. Oh, BTW, my speaker cables were mid-fi copper (10 gauge) if that makes any difference. If you are going to use a tube preamp (as I now have) it will warm things up some. Your Classe will be a little smoother than my Bryston so silver IC's may work for you. While I am sure the best advice is to demo what you can or at least get a return policy, if you are at all interested in silver IC's then try out Homegrownaudio.com or Delta Labs (more expensive)Synergy Reference S-7 IC's. I would stay with copper speaker cables for now and try out various IC's. I think you may realize more apparent differences with playing with your IC's now rather than get speaker cables at the same time. If you need speaker cables a suggestion might be Analysis Plus Oval 9's. My Oval 12's have started to break in nicely (not very nice out of the box) and the 9's are a reasonable price. Just my 2 cents worth...
