The PS Audio devices are limited in their capacity to alter AC frequency. They were designed to supply regenerated power for any audio gear. However, if your tt is running at correct speed direct off the PS Audio, there may be little to gain by inserting an SDS. Not nothing, but "little" to gain. Unless the PSA is dedicated to the tt, you probably don't want to alter the frequency of its AC output above or below 60Hz, in any case. That might be bad for the other gear.
speed stability
Does anyone know if using a device like a PS Audio power regenerator accomplishes the same speed stability goal as using the VPI SDS controller? I have a VPI Classic turntable and run it, along with the rest of my audio components (except the power amp), through the P5 Power Plant. Since one of the goals of the P5 is to deliver a nearly perfect 120 volts, is an SDS superfluous?
Thanks!
Thanks!
