Well, i guess I want to reopen this thread. I now have seven Star Sound Tech Apprentice Platforms as well as a lot of StillPoint devices. In terms of philosophies the two are quite different as the SPs seeks to convert all vertical vibrations into heat and Star Sound wants to transfer all to ground. They sound quite different also. The Star Sound are very quick sounding with sharp leading edge. The Stillpoints give a very holographic image, which may or may not be real.
Under my speakers the Star Sound platform worked better given the design of the BMC Arcadias as well as sounding better. The same is true under amps and my Koda preamp, which I should say is a hybrid use of both. The Koda sits on an Apprentice, which sits on a Accapella platform sitting on the rails of the Stillpoints Rack.
My best advice is to try both. I also think this thread ignored the Stillpoint Ultra Minis which on light devices are excellent. Most of my source components are on the Ultra Minis. My Nantais Lenco Reference is on a separate Stillpoints Rack on Ultra Fives, which were clearly better than the Ultra SSs.
