Thank you George/ Ronnie for the additional insights. It sounds like I should seriously consider looking at the DSP6000s, especially as it seems that they're a similar price to the DSP5200 (if not less). Although, I must admit the newer designs do look much better!

Sonically, are upgraded speakers the same as their later versions (e.g. D6000s vs DSP6000 MkII), as I noticed they sell for less. I assume this is due to cabinet chnages?
