QSA Power Jitter Power Conditioner, anyone tried it?

I recently added the QSA Red and definitely heard an improvement in the sound quality. I'm using it on the power cord for my Gigawatt Powerprime power conditioner. I noticed better separation between instruments, a bit more presence/oomph, and definitely an appreciable difference in bass -- tighter and punchier. In fact, the improvement in bass response is such that I have switched off my two REL subs and can still enjoy jazz, vocals, classical. I only turn on the sub when listening to rock, EDM, etc.

Having said that, I also have a QSA Red Receptacle so not sure how much of a role is it playing here. I don't have any experience with the Yellow or Violet.

When I put the Red in my system, the improvement was immediate and very noticeable. It only got better after a few days.

@willgolf Yes I tried it with my amp this way. Then I switched back to using it with the power conditioner. I didn't really notice much of a difference to be honest. But as usual YMMV. I think TweekGeek still offers 30 day return guarantee. That's a really good deal if you ask me.

@willgolf -- not surprised at all that you liked it :)

As I already mentioned to you, I was all set to sell my QSA Red jitter in my second system to fund another purchase. I was getting ready to put it up for sale, but removing it from the chain had such a drastic effect on the SQ that I just couldn't bear to part with it. I know there is a lot of skepticism about this product since it looks so ordinary. But it works!

I also have the QSA Red Receptacle in my main system which had a similar impact. It added a more organic signature to the music ... more relaxed and expansive.
