Mijo, I don’t disagree with your general principles, except as regards the prime importance of speed constancy, which I emphasize more than you, apparently. But then you come down to recommending the Star Sapphire, a spring suspended belt drive. I owned one for 10 years as my only turntable. At the time, I considered it an entry into the high end of Audio. I ran a triplanar tonearm on it, for most of that time. I only later realized that vinyl reproduction does not have to include unstable piano and violin notes and muddy bass, which is all I ever got from the Sapphire. I went from the Sapphire to a Nottingham analog hyperspace turntable, also belt drive. It was far superior in all ways, especially after I added a Walker motor control, using the very same triplanar tonearm. I just think the sapphire is not a good choice for a paradigm. I do not mean by this to demean all of the Sota turntables. As I understand it, they have made some major improvements since the sapphire was their flag ship product.
