There are other folks that have had the opposite experience, finding that a regenerator diminished the sound quality and a Puritan system improved the sound quality.

I believe it has a lot to do with a variety of differences in AC from home to home and also the way ones components interact with AC.

There have been many threads and reviews of Puritan products over the last four years or so. I think it's accurate to say that for every 100 Puritan users, 98 or so, after 200 hours, find it beneficial and a couple do not.

I use Puritan products in both my consumer stereos and three production studios, two of which are at different locations. In each case, I hear a worthwhile benefit. It's especially apparent in the production studios.

My experience was similar to @audphile1 in that I did not experience improvements with the Puritan, and it had a slightly negative effect on my listening experience, though I could not say exactly what was wrong. I gave it sufficient time, running it for a couple weeks. I tried it with the Classic+ cord, and a Neotech cord, no significant difference.

My ultimate goal with power for my system is to get that late night sound 24/7. To replace the Puritan, I bought a used PS Audio P12 regenerator that I am using for my source components. I have had that in place for a couple of weeks, and it has brought me very close to my goal. I am impressed with the P12 for sure.

This is not meant to be a ding on the Puritan at all, it is well built and I am sure it is working well for a lot of people, it just did not do it for me. 

My experience was different. I noticed reduced dynamics, pinched highs. Soundstage was not great. I ran it with Classic and Ultimate cords and even had AQ Hurricane on it for few months. 
Plugging amplifier into it reduces the sound quality even further. It may be ok for source components especially ones with switch mode power supplies or ones with inadequately designed linear power supplies. 
I would recommend a passive Shunyata power conditioner over the active puritan. 
Best to try before buying or buy used.

@xcr33pshowx - I believe Jaguar Audio out of Seattle might provide trials on the Puritan units. BTW, I highly recommend the Puritan product. Without question it improved the quality of two different systems in my home.
