Hi Lee,
I have the standard Space Deck w/AceSpace arm. I actually like the cheapy little foam mat that came with my table, but sometimes it can stick to the record when you flip it over. Other mats can change the sound, but ask yourself,,, does it really
improve the sound

Here are the tweaks that I am using with my Nott as of today...
1. Stillpoints Ultra LPi. This thing is hecka cool because not only does it work magic on my turntable, it also performs a small miracle when sitting on top of my CD transport. Two tweaks for the price of one.

2. Boston Audio Mat 1. I like this mat in combination with the Stillpoints LPi record weight. However, without the LPi isolator, I prefer the stock foam mat.
3. Four Herbie's tendersoft Tenderfeet under the stock Nott base.
4. Ginkgo dust cover.
- Tweaks/changes that I am contemplating ....
1. Symposium Svelte Shelf to replace the stock Nott base, or
2. Stillpoints Ultra footers to go under the stock base.
3. A new tone arm and cartridge.
4. A better or different phono stage.
