Hello, I am new to the forum and have been watching Paul on YouTube for years! I learned a lot of information from him and I certainly appreciate his hard work. I am interested in purchasing either a P12 or P15 Power plant and I wanted to ask the forum members for advise. I was hoping a P12 would be adequate for power in-regards to my current setup. McIntosh MC205 5-channel amp 200Wx5 channels. McIntosh MX121 pre-amp. 75W LG OLED 65" 4k. Estimated 125W REL T/9i Subwoofer 300W Apple 4K Lumin D2 wSBooster. Sony 4K Dvd Player. In closing, my hopes are the P12 is enough to power all the equipment, but I am willing to wait to afford the P15. I spoke to PS Audio already and they are leaning me towards the P15, but I wanted to see if anyone else would like to offer their opinion. Thanks, Leo ---

You have too much draw with everything plugged in. Demanding passages of music will overload a P12. Idle might overload it. You need P15 or a P12 without amp. Rule of thumb is that the transformer in powerplant needs to be as big or bigger than your amps. ---

Thank you for the feedback, Watchdog!! I was thinking the same thing, but I had to ask. I am currently using a Furman Elite 15PFI in my system, but with my amp plugged directly into my wall. I was hoping I didn’t have to break the bank with the P15 and save some coin during the holiday season. ---

There’s always gently used stuff around. PS Audio has transferable warranty of 3 years. ---

I decided to purchase a P 15. I will let the forum know about my review after I hook everything up. ---

I’ll put it out there again, I think a used P10, in great shape, is the sweet spot of PSA power regenerators. I’ve owned a PPP, P3, P10 and P20. ---

This is my first PS audio regenerator. I bought a P 15 new to try it out and make sure I like it. I am very optimistic that I will considering I am using a Furman right now. ---

Hi @Leo1. I’ll be interested in hearing your thoughts on how the P15 compares to the Furman. I compared my P15 to what was my tried and true Running Springs Haley and the P15 was much preferred. ---

Hello Tony22, I certainly will let you know my opinion when I hook it up. I don’t receive it until next week with the holidays. My Furman has been just fine in my system and has improved the sound. However, I don’t have my amp plugged into it and directly to the wall. All I hear is how much the P12,15, and 20 improved the performance in their own systems. I had to take the Pepsi challenge and see for myself. How much did it improve your performance by? I try to use percentages, even though it’s all subjective. Merry Christmas!! ---

Hmm, that’s tough to say, @Leo1. I don’t think of looking at improvements in terms like that. I can tell you _where_ the improvements were heard in my system. Improved resolution and detail retrieval resulting from an improved sense of “blackness” - lowered noise making everything sound “clearer”. I don’t know - maybe 15%? May not sound like a lot, but my system was and is already pretty d@mn good. 😁 Good luck! ---

That’s awesome to hear, Tony! I know it’s hard to quantify based on a percentage base. I’m in the medical field and always use physical measurements in my practice. Lol. I like hearing from other members about improved “Blackness,” lowered noise floor. That coupled with better dynamics and a wider sound stage make this purchase very enjoyable. If I can get a 15% improvement like you have, I’m pretty excited. ---

I’d say my P20 improved SQ by about 5%? The improvement I hear is consistent with tony22’s experience. Icing on the cake! ---

Thanks Kylemillsap, I appreciate you sharing your experience. I do realize it’s system specific with the amount of performance expected. There are so many variables that play a key as well. I am hoping to see a significant upgrade, but only time will tell. ---

Well, I officially have my P15 set up in my system for the last 3 days and I’m impressed. There was a lower noise floor immediately that I noticed. Also, better dynamic range, especially in the base region. The soundstage was wider with more air. You could really feel the snare drum snap and symbol crashes. I would say there was a noticeable 10 to 15% increase in my system overall. I’m still working out what sounds best with upsampling between Roon and my LUMIN, but it is actually fun. Lastly, I am trying to figure out what multi-wave setting to keep it on. It seems to me that the majority in this forum likes the number six setting? ---

I use the MultiWave setting that gives me the best “Improvement Factor” and that is a bit different depending on the time of the day but generally I get the best/highest “Improvement Factor” with my MultiWave Strength on 3 and my Phase Tune on -3 I also have a P15 ---

Thanks for the reply, Birger. I did notice an improvement on MW 6 and 3. I haven’t played with phase tune yet, but I read the normal setting should be on 0? I’m still trying to wrap my head around these settings and what they do. ---

Yes, Paul says that you should only use Phase Tune in “Extreme Conditions” but I don’t understand why they’ve even put it there if you should never use it and in the same time gives me the highest “Improvement Factor” so I happily use my Phase Tune anyway. It also gives me the most silent P15 in the same time as a bonus. ---

I agree that if you found Phase Tune to improve your audio experience, then by all means keep those settings. I enabled Auto tune a few times and it kept using a setting of 4 & 6 on MW. However, Phase Tune was kept at 0. I am getting O.1% for THD on my output side, but I will certainly play with PT to see what kind of improvement I may or may not receive. ---

When I use Auto Tune my Phase Tune varies. Most often it stays on 0 but sometimes it can also come to +2 or -4
