Soliver,I think you hit it correctly.More filtration,with "balanced A/C",which seems to be desirable.
I don't want to do anymore PS-Audio bashing.The UO's I once had,were superb,and the power cords are very good.
My friend's P-300 works well,and he has added a Balanced Power Technologies unit to his Rowland.He's getting it Friday.
My P-500(both)sounded very good on my front end stuff,and that is why I got so into the "Power Management" business,in the first place.
What got me so pissed off at PSA was that I bought the P-500 to protect my stuff,and two units failed,in short order,back to back.The second replacement P-500 came with a loose surface mount resistor,that I found in the bag.SORRY,this represents poor quality control!Oh,I forgot to mention that my first P-500 came with a broken power cord.The prongs were bent inwardly.Attention to detail?
Also,every time they release something new,the previous models start to sell for enormous discounts.To me this represents an almost "product dumping" onto the market,and with my terrible experience,and the subsequent failures of their product(jeopardizing my expensive system)I am turned off.For the time being.
The Power Plant Premier does look to be a wonderful product,and sold at a fair price.I hope it is long term reliable.My two Statement power cords,which hook up my Exact Power stuff seem very good.
One other point......You MUST educate yourself(web material,etc)as to some of these things,and then form an opinion,based on reading,and feedback from others(btw,The Cable Company has a free lending library,for Exact Power stuff,among other things).I actually had a representative from Shunyata call me(after I had left a message questioning a power cord,that I was considering)and he was almost militant about how the "regenerating" products are a waste of money!Of course he wanted me to purchase a Hydra.I mentioned that I had already purchased my unit,but he railed on,which is a bit much,IMO!
Well,he was wrong.The regenerated A/C DOES sound better.I am absolutely convinced of that.Under any condition!!Even if you have great dedicated lines,as I supposedly do.At least that was what an electrician just told me.
There is s ton of noisey DRECK coming in,through these lines,and we supposedly have quiet,sensitive circuitry.Why would Shunyata sell power cords claiming they make a huge difference,and in the next breath,the guy tells me regenerating does not?Please!!!
I have a friend(very experienced hobbyist,LP collector extroadinaire)who is famous for his statement of "if you put a banana on any piece of audio equipment,you will hear a difference".
Also,I suspect(just a theory)that the really good(elite)solid state products are getting so good,in frequency extention,and distortionless performance,that they will benefit the most from regenerating A/C.Look at the Dartzeel preamp,or ASR stuff.Already,they have addressed the A/C issues,and the response to their products are incredible!
I say this,all,because as I personally prefer the sound of "quality" tube stuff,to SS.Yet my system is a highly modded SS based set-up.The only tubes I have are in my phono section.BUT,BUT...now,with this lowering of noise,which I did not even know was present(I was really quite happy with my sound,before)my system has taken on SO much more "musical beauty",from my software collection,that I truly have a hard time giving the sound a "Tube or Solid State" personality.I cannot wait for my tube loving friends to come over.I am actually considering(as a joke) putting a covering in front of my ultra modded Rowland,and telling them to try to guess which "tube" amp I have bought.They will definitely fall for this,as the sound has SO changed for the better.
Sorry for the length,of my post,and I am done bad rapping PS-Audio.I am sure my experience was not in the usual norm.
Best to all!
