QSA Power Jitter Power Conditioner, anyone tried it?

@tommylion I'm open-minded regarding audio tweaks. A few weeks ago I purchased one QSA Power Jitter Power Conditioner - Yellow, the least expensive one offered. I'll admit that I need to give it additional break-in time and try it on additional components in my system but thus far I've heard NADA!

@lak 

Thanks for sharing. May I know how exactly you’re using the QSA - Yellow? Are you using ahead of power conditioner or on individual components?

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.
