What's your favorite Turntable tweak?


I know that this is a huge topic, but what's your favorite tweak (or if you consider it a necessity) for obtaining the maximum from your analog rig?

This can be anything from a new record mat, to vibration control (ie, ginko clouds), to alignment tools, vinyl cleaners (favorite vacuums, cleaning fluids, brushes, etc), record sleeves, anti-static guns, etc.

Along with your recommendation, please feel free to mention specific brands that you recommend.

In advance, thanks for your input!

Raul, perhaps he still has the MusicHall MMF 7 he mentions on another thread, which appears to have been added after the last post on his system thread a few years ago.
Favorite tweak, once all else is copacetic = AC motor controller. I guess I would not call proper alignment of the tonearm/cartridge a "tweak"; it's a necessity.
The most amazing tweak I have is and independent support for the arm on my Technics SP10 mkII, it is just amazing the amount of detail and tone I got from that.

Lewm, I agree with this for turntables with AC motors -- a good motor controller makes a material difference. For example, I've heard the improvement on every VPI turntable I've tried this on, and Harry Weisfeld strongly recommends it.

If you can spring for the additional cost of a Walker Audio motor controller, that's yet a bigger improvement. Hard to believe a different controller will make a difference, but everyone I've demo'd this difference for has wanted to make the shift.
