I also agree.
I notice with each vibration enhancement, power cord, power conditioner and interconnect, I get a touch here
a touch there and it just keeps getting better. On a per dollar scale, I got more bang for the buck out of about
1200 bucks worth of room treatments, but it all helps.
One day just for laughs, I unplugged everything, put cheap RS interconnects in, stock power cords and plugged
straight into the wall. The sound collapsed pretty significantly.
