I have, using an Sbooster.
I believe any improvement to SQ was the result of reducing noise in the system rather than improving the performance of the turntable. After reconfiguring my system that Sbooster now powers an Etheregen and I went back to using the stock wall wart for my Stealth.
The Stealth still sound great, running a Sumiko Starling through a Rothwell MCL SUT and Hegel v10.
