Impact of Walker Audio Extreme SST

I am ,like many of my audiophile brethren, always looking for a way to improve my system. For several months, I have followed comments here and on audio asylum about the benefits of Walker audio sst and extreme sst contact enhancer. I must say that I was a skeptic, cryogeniclly treated silver particals suspended in some sort of vegtable oil for $150. Well being the fool I am and believing what my fellow audiophile had written, I decided to take the plunge with both feet. The product seems absurdly over priced but the results were well worth $150. The benefits were across the board. In particular the soundstage is better defined, individual instruments and vocals are better defined and more 3 dimensional, bass seems more there and taunt and the highs are more airy but not at all agressive. I was wondering if any members have recently experienced this product. By the way my system is composed of Theta Basic II transport, Camelot Uther IV DAC (direct to amp), Tara Labs Air 1 interconnects and speaker cables, Rogue M-150 amps and Audio Physic Virgo II speakers.
