The B&Ws I'm planning on getting are the new 604 S3. I've read several reviews from owners that have suggested the use of around 200wpc is needed to brive them at their best.
I have the 1095 and bought it over the 1075 because I plan on buying some power hungry B&W speakers. Unless you plan on driving power hungry speakers now or in the future or play music or movies at incredibly loud volumes levels. the 1075 shoud do fine.
