I had the 802's. They sound very similar to your 803's.If you are already listening to them with the Cambridge and don't have any issues with the tweeter, I would recommend a class D integrated. They run very cool. The preamp section usually runs hotter than the amp section. If you could get a good deal on a used PS Audio, that would probably work well. Also, I think the newer Rotel integrateds are class D. That should be good as well, given that they are the same company.
Need cool running integrated under $1500 new/used
I have a second system with a old pair of B&W 803 series2, and I need a cool running integrated that can power these (maybe 75wpc and up?). I want to be able to leave the amp on 24/7. I currently have a Cambridge 850 that sounds great but gets very hot. So, going to replace the Cambridge, but with what? I would prefer an integrated with two speaker outputs (A+B and A or B), but open to all suggestions. Thanks much...
