If yes, how much (%) the sound becames really better?
Worth?
Which is the best brand?

I have been using PS Audio regenerators for years. I currently have my entire system connected to a PS Audio P5 regenerator, with the exception of my two powered subwoofers.  Even though the power I receive from the wall is relatively clean, (1.7% THD).  After regeneration, the power my equipment is being fed has .1% THD.  That is clean power.  The cleaner the power you deliver to your system, the cleaner each component begins its job of contributing to your system's musical performance.

The P3, P5, P10 series was a huge performance jump for PS's regenerators.  The previous model, the Premier Power Plant, although designed at PS's Colorado home was manufactured in China and reliability and therefore performance was problematic.  Example.  I plugged my entire system into my PPP and the power demand toasted the regenerator. PS Audio, being the customer service oriented company that it is, sent me a new PPP.  That was fine, but I had to buy a Duet power conditioner for my power amp. so I wouldn't toast this PPP.

Knowing the problems with the PPP, PS set out to redesign their regenerators and that effort gave birth to the P3, P5, P10 line.  They offered a generous upgrade stipend if you returned your PPP for one of the new models.  That's how I came to have my P5. It is designed and built in Boulder, CO.  It is built like, well, a tank!  Even with my power amp. plugged in with the rest of my system I am only using 30% of its capability!

PS Audio has recently redesigned their line again.  The P12, P15 and P20 are their current offerings.

Paul McGowan and Co. are a class outfit!  If you would decide to got the PS route, Don't get any of their models that precede the P3,5,10.

I love the sound of my system with the P5 and it is staying put.
@jbrrp1   Great point about the sound of the system not varying with time of day like it often does without regeneration!  That was one of the main reasons I bought my first regenerator, the P500, years ago.  You are right about the heat.  It was tough to run in the summer.

Oner more point I failed mention about my P5.  It does not restrict the dynamics of my system at all to run my 275 watt/ch. into 6 ohms SS amp off of it.

I'm listening right now to the Reference Recordings LP of Mike Garson's Oxnard Sessions Volume 2.  Spectacularly dynamic, spacious, just lovely sound.
@inna   That's great!! I'm glad to hear that your PPP is working so well for you.  You are probably experiencing a significant improvement as you state you have "very dirty" power.  My incoming AC only has 1.7% THD.  From what you are saying your THD would be significantly higher than that making your PPP a true godsend.
@vtvmtodvm
The P5 display window shows the amount of incoming THD and outgoing.  It tells you what percentage of the P5's capability you are using as well.  In that way you can tell if you are unduly taxing the unit.  In my case I appear to be in good shape as I am using only 30%.  By pushing once on the display's touchscreen you can see the incoming sine wave, push again for a visual display of incoming distortion on that wave and one more tap gets you the outgoing sine wave.  

Paul McGowan has been a believer in power regeneration for a very long time.  It just took time to develop the technology to the point where it is now.  It's been an interesting journey for those of us who've been riding that train for some time!
@bazza You said:  " You should remember that sinewave is the only safe mode for tube equipment ".  Upon what is your statement based?
