Classe and B&W are under one holding company. Question: Why not look up the bricks and mortar audio stores from around the U.S. that carry these two brands and get opinions from some of the staff about ic's and SC's or at least view the cable brands their stores carry? I believe the retail outlets are required to merchandise both these brands, at least that's the case at audio store in my location.
btw I have a Simaudio W5.3 amp and B&W 805S and use Transparent Audio mm1 super ic's and am soon to acquire mm2super speaker cables for Christmas. I like the ic's and pretty sure the SC's will step up to the plate.
On a slightly different wavelength, from my taste of reading AG discussion forums, tubes are hot, old fashioned solid state not so much. And on this forum it takes a brave soul to say he likes his B&W's, often soon followed by a disparaging post that would make you think that guy's B&W's up and left him for another man. Maybe, content, B&W owners grew wary of this and just aren't participating in AG forum so much. But who knows, I could be off the mark. In a newspaper story photo, I saw my speakers in Jack White's Third Man Records headquarters in Nashville (WSJ 7/10/2009 edition), maybe B&W paid to put them there but still..., oh and I just turned up my humidifier to get some more of that English dampness in my listening space.
