It's really a question of whether the highest forms of modern technology are being applied to tt development at all. Perhaps the Monaco Grand Prix tt is an example that would tend to answer the question in the affirmative, but there are not too many others in the same ballpark. I guess I would add the Raven and Brinkmann products from Germany and the Saskia, the Walker and the Teres/Galibier efforts in this country. Possibly Transrotor and maybe a few others (Caliburn) could be included. These are all megabuck products.
Megabuck doesn't mean the best performance. There are two examples realized right here on Audiogon... A Brinkmann that was smoked by a Garrard 301 and a Walker Proscenium that was outdone by a Technics.
