Phosphor Bronze Platter? That's very interesting! I remember some guys at DIYaudio we're running a group buy for stainless steel platters...
To acquire a Phosphor Bronze Platter is a of a unique design for a SP10 , will prove difficult if not wanting not spend fortunes.
I got this Platter after a long hunt, not a Cheap Option, but I am hoping that due to its design, I can make it work, with a
SP-10, TTS-8000, DP-80, PTP Solid 9, and at a later date my own built PTP -6 with it own plinth to work with a design I am working on.
The Plan is to produce a Plinth that has a Permali Wood Picture Frame perimeter that the Tonearm is attached on to,
it is looking like this will be produced to work with a 9" and 12" Design.
Each TT will have its own Plinth Produced, that is cut out to produce Tonearm to Spindle dimensions, these Plinths, will insert into the Picture Frame Perimeter, I am yet to decide on the insert plinth material, or from a recent discussion the finished shape.
I have yet to go back to the drawing to work out the shape I can produce, that is not equilateral.
I suppose the question is why got to such pain/extremes, well firstly LH is responsible for that, it is all about the 'Spirt of Creativity' and is a Magnet to the types who like to Ponder and Do, or like me, Ponder and have others do on your behalf.
The main drive was that after undertaking many years of travelling and meeting HiFi minded people, at their homes, at my home, at events.
At times when devices were brought and compared, especially TT's, if TT's were compared they usually had different
Plinths/Tonearms/Cartridges and would usually be on different Stands.
With a TT each of these variables will impact on the overall presentation and SQ.
I was in the past going through the motions of attempting to put a 'GL75 Platter Spindle Bearing Comparison Trial' together,
there was support on offer to supply Donor Bearing, off which I believe there were six types that could be trialled, I was hoping all could attach to the Solid 9.
It was important to me, that one TT would be used for the presentation, and one TT would be used to give the bearing a run time, before it was mounted onto the TT doing the presentation.
Additional for me, it was imperative that one TT-Plinth/Tonearm/Cartridge/Stand, was in use for this assessment.
My latest Design for the Plinth, is a extension of this concept.
As I can insert any TT I can make work in the design, and assess it against others with the exact same environmental controls in place.
Hi JohnG,
this looks like a very interesting suspension you use under the plinth. Can you tell us something about?

The feet being witnessed are SolidTech 'Feet of Silence' (FOS).
These are my go to feet, they are the final choice from a very long period of trialling footers,
these produce very obvious changes when put under certain TT's, and my experience is that the most noticeable is when placed under a Idler Drive.
I have taken these to other properties, and put them to use on TT's that are Belt Drive and Idler Drive, the owners of these TT's,
have expressed how noticeable the improvements have been, when compared against footers that they thought were very good choices for their set up.
I have not really compared them A/B against other footers on a DD - TT as these are now my go to ones.
The Previous Posts Image has not shown the Sub Plinth, which is another consideration to be addressed, my Sub Plinth is a
Phonotherm Board that sits on Audio Technica AT-616 Pneumatic Footers.
I had high hopes for the Phonotherm as a Plinth Material, but following reports returned on a test it was put through, it is not a improvement on a Ply or MDF, so it will do fine for some jobs, but I don't see it becoming a Permanent Plinth Material.
One of the TT owners who has used these has now made his own DIY version using a elastic suspension, he is claiming he is still noticing the improvements that were on offer, but these have not been A/B compared.
Another group who have heard them, have sought out more affordable products to offer a impression of these, but more importantly, exchange the usual footers being used, I know they have chosen a Brand Isocoustics ?? (The Model GAIA III),
I know these have cleaned up the improved the Deck, and on later investigations, improved Speakers as well, both Box and ESL.
The group are keen to do a A/B once more with (FOS) on the TT's.
