Thanks for the feedback on the SDS Paul - that's very encouraging. I'm using the original oil-filled mat on my Sony and it does work extremely well. I tried an Achromat on it and wasn't convinced, it seemed to cause a 'suck-out' in the upper bass which whilst appearing to clean things up it made pitch coherence slightly vague, robbing instruments of body and colour. Didn't take long to convince me that the Sony mat was better but I'm usually open to trying other stuff.
Richard.
