Guys,

Support feet and mats are largely system-dependant, just like everything else - there is no one universally 'correct' solution, so you just have to 'suck it and see'

In the context of my system, Dave's mat and the Isonoes work best. I haven't tried the SRM acrylic mat on my 1210, so I can't comment on that (perhaps we could try that Shuggs next time you're up?), but the Sorbothane feet were truly dire - reducing dynamics, bloating the sound, and killing the music in the process. The Isonoes were just so much better in every way...

*But*, as I say, that's only in the context of my system - and of course my Techy sits on glass, not to mention many multiple layers of Mana supports!

Marco.
