Technics SP-10 Tonearm Pod instead of Plinth/Base

I have such a setup, I got an Sp10, I took out the plinth, given a cheap one, but it was like taking the bell out and leaving only the little metal ball inside it.
I made a pod for the tone arm with 3 different metals and it is pretty heavy, trust me it wont move. The Sp10 is sitting on its own with no plinth at all, I have cones holding it from the original chassis, we actually discussed even taking the chassis off.
The improvement was impressive, in micro-level detail and air around the instruments.
Isolation is very important and the cones that support the SP10 can change the tone of the setup, for a tubed Phono preamp I like solid steel cones, for SS I use the famous Audio Technica Support Isolators with metal cones. Actually my favorite sound came from a combination of cones.

The Pod base stands on cones also, that improved the sound a lot also.

I dont want to rub the people with plinths the wrong way, this is my private setup and I like it, my system consists of triamplified 5 way horns.

Check out theanalogdept.com/stefano_bertoncello setup, he uses a Garrard with a Pod also.

About the Theory of Mechanical Linkage of the TT chassis against the tonearm, in my point of view, less vibrations are better than "joint" vibrations. Now to theorize here seems a bit ridiculous but any way I will give it a go: To have a synchronized vibration could work in order to lets say minimize the sum of vibrations, but this would mean that both the Tonearm and the TT are at the crest of the vibration at a given moment and at the valley, in complete synchronization, if one is at the valley and the other at the crest then it is better to have them Isolated, in a separate Pod. Now, in music we know vibrations are in a lot of frequencies, not only at one, so to have a synchronized movement that would annul the vibrations in all frequencies seems a bit complicated.

This would be theorizing on a result I found in practice, I dont know how valid that could be since we could also theorize on the contrary.

Practically I like it better.

I dont think it is a question of who is right and wrong, This is a wonderful Turntable exceptionally well engineered, it was designed for professional use mainly in a radio station, what you need there is precision and reliability, for a High End Turntable you need only good sound, In High end we dont care if your power supply is ready to explode or your cables can catch fire at any moment, or if your speakers barely fit in your room, we just care for sound. I dont think a separate Pod could be fit for a radio station.

Audi uses the same engine for a station wagon and for a sports car, the difference is on the application and what you need it for, you want to carry 3 kids or you want to go fast!

A lot of High end TT do have a separate Pod for the tonearm, and on the SP10 in my experience the comparison is not even close, plus it is very easy to implement, try it out and let us know your opinion.
