I have a stock Technics SL-1700 in my bedroom system and it's a fine table even in un-modded form.
I read a post on another forum about someone packing a cylinder of foam inside the SL1200 series arm tubes, and putting a plug in the back to dampen resonances, they do it during a rewire and it really improves the stock arm. Jelco and other manufacturers do the same thing apparently.
I am planning to do this to my SL1700 arm when I get around to it.
