Good choice again. I have read good reviews on the "W"s and they seem to be a major step up from the "V"s. Coupled with the Simaudio amp, sounds like your on the way to a great system.
WRT speaker cables, you are bound to get a wide variety of opinions, all equally valid and good. I use Audioquest Rocket 33's in my system. After trying many different types, I am very happy with these and have no intention of changing.
