I'll try to control myself! :-)You'll note in "systems" that I use a suspended table, and have for years. In order for it to work properly you have to be able to adjust the spring tension (if your turntable doesn't allow for this you'll have difficulty getting its best). That can be just as important as correctly setting up the arm/cartridge. And you still have to deal with some sort of additional isolation devices. Also, when changing arms on a suspended table you could well have to change the springs, assuming that the arm is somewhere withing the tolerences of the design and the manufacturer provides alternative springs. This limits you somewhat as to what type of arms you can use. Also, uni-pivot arms don't usually work well on suspended tables (they don't like all that bouncing about :-). One of the reasons I favor the Nottingham is the way the designer has delt with isolating the motor off the plinth and the design of the motor. One of the best tables I have owned was an old manual Mission with a motor so "underpowered" that you actually helped it to start spinning up to speed by rotating the platter and to use a dust brush. However once it was up to speed it was dead quie and spot on. This is how Nottinghams are designed (I assume you've read up on them already). The last reason I favor the more recent designs of non-suspended tables is they allow the use of heavy platters which contribute mightly to speed stability. I can't stand pitch variations!
I have not heard both designs you refer to in my home...I'm basing my comments on my understanding of the designs involved and consumer feedback re quality control. In the near future I'll be putting my money where my mouth is, i'e' probably a spacedeck and arm.

No, you don't, and in fact, you should not; performance will suffer if you attempt to "isolate" a properly suspended table.

I will just have to audition a VPI table - I'm sure it solves all of the many problems facing turntable designers. :-)
> I will just have to audition a VPI tableFrom an engineering standpoint, VPIs are no better or worse than similarly priced suspended tables.

This is why I haven't done anything in 19 years. : )Maybe I should just forget the whole thing.....
It's all about the music...
Obviously, I'm still using an old Oracle...............But one day soon, perhaps. Fun to keep up with whats going on though ....there really have been some great improvements in the past 20 years but none come cheap anymore.
Adjust the spring tension?!I'll be honest. I'm moving the gear up into the attic as I'm putting a dedicated room in up there and when I took the table off the wall mount I cleaned it. While doing it I noticed the bottom cover was sagging, so I took it off to reverse it. This was the first time in 19 years I have ever done so. Not only did I not ever consider the springs, I didn't know adjusting the tension was possible or done. In any case I would not have screwed around with it.
I have always gone to great lengths to remove mold release and clean ever record on a machine. I also set the table up dead perfect. But beyond that, I have done nothing. I consider what I'm getting to be quite good. I consider cleaning the vinyl and proper setup 85% of the battle. It's only now I'm worrying over the last 15%. : )
The bouncy-ness of this platter has bothered me for years however, even though it does stay put when playing on the wall mount. But record clamps I tried did not work with it thus precluding their benefit and for what it would cost to replace the arm and motor I think it would be better to go with modern technology.
Thanks for the input.
