PS Audio Soloist Premier SE

I have the PS Audio Soloist Premier wall receptacle up for
sale.  These are rarely on the second
hand market for sale.  The original price
was $250 and I am asking $150 each. 

"The PS Audio (PSA) limited edition Soloist Premier SE
is a ''wall mounted surge protection and resolution enhancement
device" that incorporates passive noise filtering and the
Power Port Premier (P3) audio grade AC receptacle. The Soloist
Premier improves upon the standard Soloist with 

the addition of an upgraded AC receptacle, higher grade
capacitors and other tweaks that PSA does not wish to divulge."  Note that this device needs to be installed
in a double gang outlet box.

Thanks for reading my
ad!
