QSA Power Jitter Power Conditioner, anyone tried it?

I used 3 of the yellows, but noticed just one had enough effect.

What’s interesting about these is that I can more easily switch in and out vs. the fuses.

I ended up removing these from my system. They accentuated the highs at the expense of mid-bass and low end. 

@lalitk Thus far I tried the Yellow on my Allnic - T1500 and Luxman 590 AXII, plugged into my Niagara 1200. Eventually, I'll get around to individual components and plugged directly into the wall outlet.

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.

Interesting.

Finally got my yellow Power Jitter in the mail today. Put it between my power conditioner and the wall outlet. First impression, I don’t see it coming out anytime soon😁 If it gets even better over the next few days, I will be one happy camper!
