Spenceroo: At RMAF in October Channel Islands were demonstrating a more powerful pair (than their D-200) of mono blocks....I think they were either 400 or 500 WPC into 8ohms. Below is a link to a picture from their exhibit room. Don't know the proposed MSRP. I own the D-200 model and the Channel Islands rep. said the new model is designed to widen the sound stage, give more headroom than the 200 model. They were demoed with a new MK3 version of Von Schweikert VR4Jrs. Sound great...but a true evaluation was impossible give the size/acousics of that hotel room. Could a used Spectron Musician III be a candidate for you?
