Hi Bernie

I have DSP6000s, and whilst it wasn't an A/B with the 5200s, I have heard the same source drive both speakers. The 6000s are significantly more open and airy, lots more detail (and not thrust at you relentlessly) and space. More articulate bass, and generally more musical (IMO). By comparison (albeit with the limitations mentioned) the 5200s, whilst very likeable, were congested in the mid/treble, and warmly wooly in the bass. Several tracks caught them out as individual bass notes lost individuality and merged into one 'uber thump' (Sting: Forget about the future). In fairness, that may well have been a dem room acoustics problem, but my abiding impression was "nice", but my 6ks certainly weren't at risk!

I do think that the 5200s address the shortcomings of the 5000 very well, they look drop dead gorgeous, and the WAF must surely be 100% To my ears though, their performance is commensurate with their placement in the DSP range.

Cheers

George
