The point of Davt's response is that the base either turntable sits on HUGELY effects the sound, which is why hey suggests the Pro-ject 10.1 for comparison.
I like the Spacedeck better too, but with the caveat that I have not heard the 9.1 sitting on an isolation platform.
Most tables that don't have an integrated suspension system are hugely improved with an isolation platform such as a Gingko.
good luck.
