4yanx - I obviously touched a raw nerve! I had heard NA at shows and not been impressed but having read effusive reviews here and elsewhere went along to a dem with high expectations.
I'd say that the Spacedeck is better than a Linn - delivering prat and better bass resolution, however it didn't match up to the expectations. It may be a good deal new or used but it didn't float my boat.
Whilst you were quick to disagree with my comment on the 'table I noted that we are in agreement about the Ace Space arm being a step up from a modded Rega.
The polarization I have come across is that flat-earthers rate the NA tables and others who prefer tubes (e.g. Hifi World magazine) consistently rate the Michell tables above the Nottingham.
