if its sound too thick ....use speaker cable to adjust . but i guess it will be fine , focus audio was thick as i know .
as what you said ,i guess cambridge play cd may be suprise !
i just read all your post , u knew exactly what u need and what you want , i guess u will play well , spl1000 ultra will be great with your b&W ,just set the crossover higher like 100 or 120 . don't need to concerned about bass, spl1000 will give you what u want.u don't need 12" if u want quality and not quantity . 12 " quantity of course better but if your room or your distance was not enough ,then 12 was just waste .
