If this turbo is anything like the VPI SDS regenerator, then the result is indeed very worthwhile on 'better' turntable equipment. Output frequency is adjustable for speed tuning, & it ramps output voltage up to full power for startup, then backs it down after startup which reduces motor noise. The SDS lists for $1000 but can be had for less at discount, or of course used. You could use an SDS with your Oracle as well.
