If one reads the 'T1 sales speil' , the reader is steered by the author, to take on board the notion, that the creation of other Competitors Companies TT's are born from an inferior foundation supporting the process through to the items production.
The T1 has made an entry to the Market Place with a stand that isn't 'taking any prisoners' , especially seems to suggest ones most expensive options are for the Buyers best if it is overlooked.
As for the T1, shortly before Covid, I was demo'd a TT, that the Owner of Long Dog Audio had been commissioned to design the Electronics.
From recollection this has been a TT, that is driven with no coupling to the massive Platter. I do believe I have heard a TT with an SME V/12, sharing a propulsion for a Platter similar to how the T1 works. The Prototype I had been demo'd may be a Production Model in today's market.
