My friend has DSP520s installed in 2 rooms and I�ll give my best impressions from a fairly limited listening time so far, so here goes...

One room with a pair of DSP520s, AC200 and MS200 (+MD600) delivers a fantastic sound. They don�t sound like they are an in-wall speaker at all and have a wonderful mid-range clarity with a sound that is very engaging. �Spies� from ColdPlay draws you into the music and gives one of those spine tingling listening moments. It was suggested to me at the Sound & Vision show in Bristol Sevenoaks last year that these are probably somewhere between a 3300 and 5200 in performance. I have a trio of 3300�s and I would agree that they are at least comparable. My friend's room is a far from ideal listening room as it is a conservatory so has lots of reflective surfaces however they still manage to deliver a great sound.

The other room (related to the thread above) is a 5 channel set up with G61R, M6 L&R, In ceiling speakers for rear and the DSP520 as the centre (again with MS200+MD600). In Trifield mode the 520 excels in much the same way as above and while the M6s provide a surprisingly good sound given their �lifestyle� styling, the sound they deliver is not for me. The sound stage almost wraps around you but in doing this the image is less focussed than you get from a more conventional DSP and I also don�t believe the bass is as punchy. With a comparable price tag, I prefer my trio of 3300�s however my friend compared (albeit in the shop) a pair of M6s and a pair of 3200�s (which have a similar tonal quality to the 3300 but with (understandably) less weight and depth in the bass areas) and he liked the sound that the M6 presented.

As you can tell I don�t have a career as a reviewer but hopefully the above is a helpful indicator!
