VPI sds vs. Phoenix engineering PSU speed control

Personally I find the SDS quite adequate.  On paper, the Phoenix is better, but I couldn't hear a difference.  The digital ouput is quite nice if you're an anal type.  I am a pro violinist and am pretty sensitive to pitch deviation, and find the SDS working for me. Of coarse, I live in the Arizona desert with little power problems....you should listen for yourself.

I agree, the VPI SDS works great.

The Phoenix does no AC regeneration, or lower the motor voltage after startup like the SDS. More noise.

We sometimes agree. LOL!

Thought this question was asked prior and it was concluded
that the Phoenix does in fact lower the voltage .
SDS is better as once you set a speed it is locked to that. Phoenix corrects speed so it would be constantly changing which could be audible.
