I have a Redpoint Testa Rosa with the drilled aluminum/teflon platter and battery powered tape drive. A few months ago I moved up from a VPIHW19MKIV. I am using the same arm, Kuzma Stogi Reference, and the Shelter 901 cartridge. I have never done a comparison with a Teres. The background noise on this TT is totally silent. I really didn't think the background could get this quiet. The difference was so great that it makes standard pressings in comparison to before sound like audiophile pressings. All the audiophile things you look for improved, deeper tighter bass, extended highs, natural bloom etc. I lived with the table for a month with their basic PVC platter. This platter was good and much improved over the VPI setup but the aluminum/teflon platter really took this table to a whole different performance level. I am not sure the the setup parameters from the SF show but I do know that this table can sound amazing when set up properly and matched to the right equipment. Other parts of my system are the, Vibraplane isolation table, Hagerman Trumpet phono, Lamm LL2 line stage, Sonic Frontiers Power 3SE mono's, and Vienna Acoustic mahler speakers.
It is true that Thom and Peter have split into two companies. It is my understanding that the technology would be shared but that Peter would be making the Testa Rosa's(Redpoint) and Thom the Quatro's (Galibier Design). I did not know Peter but Thom is a great guy to work with and very knowledgeable.
