What TT upgrade from tweaked Thorens TD160

Actually, I'm kinda reluctant to sell the 160. If I could solve the jiggle problem I'd be happy. Right now I have it sitting on the window ledge of a bay window behind my component rack and althought the setting eliminates the jiggling it is a very inconvenient location. A wall mount bracket is out since the window is in the way and the wall becide the window is directly behind my speakers. Although the back of speakers are about 30" out from the wall and there is room for a walmount shelf. I think the bass energy back there would be detrimental to the TT.

I'm seriously tempted to rip up the carpet and plywood underfloor then brace the floor joists to the cement floor below - only a few feet at most since this room is an addition built over the former garage floor. But, I'd like a simpler solution and I suspect that while the bracint will help, it probably will not completely solve the problem. If I can't find a good anti'jiggle solution the TD will have to go. Soulbass, give me your email and I'll contact you if I decide to sell - but probably not for a few months yet.

V,
I'd be willing to try defeating the springs; shouldn't be difficult and of course, reversable. Will that have a detrimental effect on the table's pperformance?

Yes, I believe altering the suspension on a thorens will take the magic away. I have read that the springy suspension is integral in thorens turntables.

Here's a suspension alternative:

I did this to my TD 150 and it worked quite well. It eliminated the footfall problem and provided at least as much "magic" as the springs. It also made balancing my far heavier Rega RB 250 arm much easier.
