QSA Power Jitter Power Conditioner, anyone tried it?

One of my audiophile buddies visited for the last two days. He knows the sound of my system very well. He immediately noticed the improvement in sound after two songs and was flabbergasted when he saw the QSA plug that accounted for it. I have tried a lot of tweaks but he said the QSA plug was the best yet. He was so impressed that he is ordering a red plug.

For those of you on the fence remember there is a 30 day trial. What works in my system may not in yours but you will never know unless you try. Personally I am delighted with what the red/black plug did in my system. 

@Iwin. --- Can you remind me exactly where you used the QSA plug in your system?  What worked best?

@willgolf my Synergistic Research power cell is plugged into the QSA that takes care of my amps. I also have a PSAudio Stellar power conditioner plugged into the power cell to give proper current to my front end components. I just posted a little detail about my system in the virtual system forum. 

@lwin ....can you please post a link to your system.  I just noticed mine was way out of date and I am trying to figure out how to update it.  Thank you.

@willgolf go to virtual systems. In the search function at the top type lwin and it should come up.
