Parasound Halo A21 - Power conditioner?

I use a PPP with my CJ 350; which draws even more current than the A 21. It sounds better through the PPP; have also used a Quintet and a Shunyata with good results. But there is NO substitute for trying it out yourself!

Well I tried, and almost immediately the sound was better. Is this a pschoacoustic trick of the mind. . . maybe. I'll experiement again tonight and do some A/B'ing. But initial impressions are that strait into the wall did sound better with more detail and better depth. IF it turns out it is better out the wall then I'll look into these theremal/magnetic brekers. Thanks to all that comments. I appreicate it.

Re Halo Dealer

I use a Furman PF-Pro R power factor correcting line conditioner (which also has very good surge and transient protection) on my JC1 monoblocks and they have never sounded better. This device has capacitive energy storage which improves (lowers) line impedance from the wall plugs so that audio transients and current surges are enhanced. Also used them with the A21.

And if you think you can anticipate when a nanosecond high voltage spike is going to enter your amps, good luck. It's not always during a lightning storm. This electrical crap can be generated within your home when arcing contacts from your refrigerator, hair dryers, and air conditioners turn on and off.

I'm an owner of halo a21,and i'd like to make some mods,but i don't have the schematic.Any help please.
