Upper Level Vintage DD Strenghts and Weaknesses

As soon as JP sends my flying saucer I'll put it in my Victor TT 101 original plinth with new teak veneer. I've got a set of the Russians AT-616's for the feet. 

@knollbrent, what Victor plinth are you using? Elliott and I have the CL2P with two tonearm boards. Elliott managed to mount a third arm on his as well.

If the  AT-616 Footer is produced in an era when Japanese Vintage TT's were in their Prime, and Yet to be superseded by cheaper Mass Produce Belt Drive TT's.
The AT-616 should be a ideal footer to a Person that is maintianing a Source in a System from that is True to the 70's/80's.

There are Individuals who have Vintage TT's ( Motor Type not so important, that have Vintage Tonearms with Vintage Wiring remaining and Cartridges from the same Era) 
To remain loyal to the authenticity is not a incorrect practice it is a choice that ceates a satisfaction to the user.

I have numerous options to hand as footers, in most cases the only real differences that offer thje WOW! impression is when the correct choice is made under a TT, thst offers a presentation that realy suits the end user.

I own AT-616, and have then in my Design for a Construction used as a Isolation Support.
The TT' Base and Cabinet Speakers are both using them.
The Speakers are seated on the AT-616 and the Sub Plinths for the TT are Supported by AT-616.

For a direct contact with a TT Plinth, in my system the AT-616 have been superseded and are replaced with SolidTech 'Feet of Silence'.
The 'FOS' have the most uniquitous capabilities, all loans of these have made extremely valued impressions.

To the point where after follow up investigations by individuals that have loaned the 'FOS' the choice of Footer settled on has been a IsoAcoutics GAIA.
As said in a previous post, another friend who has a bespoke produced Rack, was so impressed with the 'FOS' he produced his own design to be used in conjunction with the Rack.
I am yet to see and hear the outcome of the project.

It is not so much about the Footer, it is about the impression a Footer makes on a end user, not all will require a particular Model or Design to feel impressed and satisfied with their choice.
As important as the Footer in direct contact with the TT Plinth is what is underneath the Footer as a Support. 
A Footers performance will vastly improve when given an environment to allow it to offer its best properties.             

The AT-616 are better (in my opinion) because you don’t have to screw them in something, you can’t do that with Gaya

In my opinion one of the advantages of the Gaia is the possibility of being able to screw them, in fact I used them in the Technics SH10B3 obsidian base to replace the original feet; the screw has the same pitch and there is no need to change anything.
Applied on the SH10b3 aesthetically they are a show but the improvement of the sound compared to the original feet is audible.
I prefer feet that screw rather than place the equipment on feet that cannot be fixed, just a carelessness by accidentally hitting the electronics and it could slip, damaging its own edge and the support surface of the furniture.

AT616 made for weight up to 60kg and with such weight nothing can slide on rubber surface of those feet. I don't have SH10B3, but a fellow audiophile in UK is happy with AT616 under his SH10B3, personally I bought them for user under Victor TT-101 and Denon DP-80 plinth.
