DSP7200VC/DSP7200HC or a DSP8kC is a large leap forward in both "airy" and effortless sound compared to the DSP5500HC.

Now from what I gather from reading the 861V6 owners comments the processor has also become more transparent and revealing compared to the 861V4.

800D is a good speaker, but the DSP8000 has so much more meat imho, give them a good center partner and perhaps a shiny new 861V6 and I think you won't look back to the B&W/Classe combo with any regret..

If you listen primarily in Trifield the center channel is extremely important and will drag down the DSP8k fronts if it's not up to par. I went from the DSP5200HC to the DSP7200HC and the difference was shocking. Moving up to DSP8kC is ofcourse a dream but will need a transparent screen for it...
