removing Studietto springs

Peter, sorry your Studio is out of service. What TT are you currently using, if any?

In my experience, the main reason for the sprung chassis was to isolate the TT from floor vibrations. SOTA, and of course the early AR employed this method. But that was during the era of extremely light-tracking cartridges, and before racks and wall shelves.

In any case I have my Studietto on a wall shelf, so floor vibes are not an issue. But the upper plinth on the Studietto was always resonant (could've been thicker IMO) and placing the sorbothane pads under it completely eliminated this. Others have also done this to good effect (see link below and scroll down to the Studio/Studietto paragraph.)

I also have my TT on the threaded Goldmund cones, which serve to drain off any energy the sorbothane doesn't convert to heat. By using these two elements (cones with sorbothane) I guess I'm following the current TT practice of using some kind of shock absorber which is then mass coupled to the shelf -- an option that may not have been available to TT designers of that time; at least there are no examples of it that I know of anyway (except maybe the original Goldmund Reference?) BTW, did you know Goldmund is coming out with a new Reference, direct drive, around $200K!~?

But, the proof of the pudding, as applies to audio, is in the hearing. God knows I've owned many TT's and though I've been tempted, I just can't let go of my Studietto. And for two reasons: first of all, I'm kind of partial to direct drive done well -- and so was/is Goldmund: now that they can get a powerful enough DD motor, they're building a DD Reference! (the original Reference was a belt drive as you probably know) And second, this minor upgrade has made my little Studietto a world-class performer -- really! Two of us did it and we both agree. Actually we started with the Audioquest half-spheres mentioned in the article linked below, but the Panda Feet come in different durometer hardenesses, which mimic the original springs, and we found them to be more effective.

I was curious about your mention of the "solid lead mat" which I've never heard of. Was this something that was particular to just the Studio?
