Power Plant 12-Initial Impressions

First, I must thank Paul and his entire crew for designing , building and supporting a eally great line of products. Okay, perhaps I am a little biased, as this is the third PS piece I now own.

I initially made this purchase for the front end of my system, the pre, DSD DAC and Memory Player along with my Internet tuner, a Magnum Dynalab MD 809t. Had pondered between the 12 & 15 for the entire system, but the weight consideration won out. I am not a spring chicken anymore and just getting the amps upstairs to the music room required calling some favors. I figured down the line I would figure out which way I was going to go for the amps (Pass 260.8 monoblocks). Discussions with Ken from Pass tried to discourage me from using any kind of condition in front of the amps. So be it…for now.

Getting the unit up, unboxed in the car and on my shoulder, was fairly easy all things considered. Requiring just moving my tapedeck to the otherside of the rack to fit it in and a little fooling with cables that were now too long took a few minutes, plugging units in to the 12, a piece of cake, a fast review of the manual (really, who actually reads those anyway) just in case there was something I might miss and blow everything into another zipcode. Fortunately a fast scan did not uncover anything determental.

With everything now plugged in and having a few more open sockets and with the meter barely moving for the front end pieces, I figured what the hell, if I overloaded the 12 it would merely shut down so I connected the amps. Okay, movement of the meters…up to around 750, so good, I have a little headroom just in case. Starting JRiver I began to run through a couple of familiar tracks…wait a minute…what is this??? did somone swap out components when I wan’t looking? where are MY speakers and what am I listening to??

Yes, I read a bunch of reviews and took all with a grain of salt…yeah, right… like opening a door…pulling back a veil… Guess what…it was no BS…it is really like night and day, literally. Everything sounds so much smoother? bass responce picked up but not boomy just there now when maybe it was not so much before. I get it, first impressions and I have no intent of swapping around a bunch of cables to do an A/B with my old Furman conditioner but I know it is a dramatic improvement, speaker upgrades are off the table for some time to come.

I would like comments as to if I am pushing it a little too much with the amps. Initially I was thinking another 12 for them by themselves down the road but now, not so sure. I will be playing for the rest of the week to see if thing change, but I tend to doubt they will.

Oh, and yes I do have one complaint, minor as it may be. I now have three remotes, okay I don’t need one for the player and DSD as they can be controlled from a single remote…but Paul, it would be nice if you could get the 12’s functions on the remote as well, even On/Off/Standby. I do have a Logitech remote and will have to check if all components are in their database so there might be a workaround. Other than that (well, maybe a 2.5m power cable would have been nice) it is all thumbs up.

Again, great job,

Make sure your software is up-to-date before trusting what those meters are indicating.

Good call as I just assumed that it would be the most current software. No telling if there were anychanges since it was boxed. But, so far so good and I have been pushing a little to see what happened.

Don’t assume, check it for yourself. There have been instances of customers receiving new PS product from dealers with 2+ year old software. Best to check, because this was a bug that was recently fixed.

Well, the good news is there are no updates for the 12 in the D/L area, so I guess I am good.

Oh, and I stand corrected, the powercord for unit is 6’, guess I need another 2’ but that is just me for my set-up. Now, on to Gustav Holst…

I enjoyed your posting very much. Your description of the equipment and feeling at the different stage of the installation and especially your ability of writing are so compelling! I think this is the best report by consumer. Congratulation. I am on the fence to decide the purchase.

I completely agree with your findings, mine were the same. As far as the display is concerned… Ah, never mind… :crazy_face:

If possible if you can get a loaner from a dealer to try on your system, it would make it easier. PSA also has a 30 day in-home trial which makes it a no brainer. Wish I had done this sooner…like most things audio related.

Thanks. It is coming for the audition next week.

Let me know your impressions.

I have found out today, that I can’t use it to come out of standby and have the amps on to come on with it. I am guessing the initial power draw is too much for it, the poor little guy… but if I start the front end first and then bring the power amps on it handles the power requirements just fine.

So no big deal as I prefer to turn off amps and let the amps drain down and then shut them down. I started doing that with a Perreaux amp which stored a lot of power as I figured it would help and it has, as I have not had to have it recapped since new. But now that I have the new amps in I will be looking into a DIY recap.
