RE: VPI analog drive system (ADS)

I have no experience with VPI's ADS, but if you want the best possible performance, you should replace your motor with a true 3-phase AC synchronous motor driven by a 3-phase generator with automatic tachometer speed control. This system was developed by Phoenix Engineering and I have one of their prototypes on my Sota Millennia Vacuum turntable. This 3-phase tachometer controlled system really improved the sound quality from my turntable in addition to lowering the noise floor to virtually total silence. I was so impressed with the improvement that I contacted the Sota turntable company and introduced them to Phoenix Engineering. SOTA became equally impressed with the 3-phase system and decided to collaborate with Phoenix Engineering to began manufacturing the system for sale to the public. The 3-phase motor system is essentially a drop-in replacement for many VPI turntables as well as for SOTA's own turntables.

I don't know the cost of VPI's ADS, but the complete Eclipse 3-phase motor system with tachometer speed control costs only $1100. I seriously doubt you will ever find an improvement of this magnitude for such a reasonable price.

Best regards,
John Elison
