Brave man, McGowan...

I was two fingers away from ordering an s300 along with the stellar pre-amp until Paul named audioquest as an example of a credible  manufacturer of good cables, because they actually listen to their products...
Yeah right, I can see audioquest listenening and tweaking their toslinks, ethernet and Usb cables... not to mention the dbs battery packs... It's ludicrous.
At that moment, PS audio lost all credibility in my book.  I'll pass.  Must be as hyped as audioquest, in other words not worth the asking price.

As I said on the title of my thread: brave man Paul!
You made my point @chrisr

@chrisr... It’s too bad you’d forsake the purchase of the S300 because of Paul’s experience or perception of the effect of a power cable... It’s a spectacular value.
However, when I read your post... I got the overwhelming feeling that grinding axes is more important to you than attaining good sound at a good price.

Just purchased an incredible $10K power amp. It brought my whole system to life - a huge deep stage, with detail, texture and timber I could never have imagined. WOW! just replaced my old ICs! The new $5K ICs make such an improvement on my $10K amp; I can’t hardly believe how much better it sounds. WOW! I just added an end all $10K power re-generator to my system - I can’t believe how bad all that terrible grid power was making my system sound. WOW!! You’ll never believe how much better my system sounds after adding a $10K power cable to my $10K power re-generator. Just when I thought my system couldn’t possibly sound any better, I put a new supper-dupper carbon fiber (coated with Graphene) cover over my $500.00 audiophile outlet. It was like removing a vail.
All satire of course, but in some cases - more fact than fiction. You can see how ridicules this all may sound too some.......Jim

That’s why it’s fun to spend 10-15 USD on those little tweaks like cheap sorbothane feet for the amp instead of standard ones, or carbon pads for speaker stands instead of aluminium+felt ones. Those can make significant and quite improvements but you didn’t spend a fortune or it, and you can really hear every cent invested paid off immediately.

I want to add a few comments. Anyone who says that " McGowan’s products are way overrated POS!" is either ignorant or has an ax to grind.I have been a strong proponent of their power regenerators since the days of the premier power plant. Have owned the PPP, the P5, P10,P15, and now the P20. They make a huge difference and everyone i know who uses them agrees with me. I have a friend who read Paul’s post about the power cords and was using a Pangea cord for the 20 amp connection. He purchased a Audioquest Thunder power cord which is way less $$ than the Dragon, and he found it to make a nice difference over the Pangea. It does not make sense and even Paul, from his comments, does not understand it, but these things do matter. I admire his courage for throwing that out there. He has a very high level of integrity and does not act from a place of greed or manipulation.

Here where I am locally there’s no much experience with P5-20 line, only one guy who praises his P5. However with previous PPP there was much experience and opinions varied. Many have claimed it made the sound actually worse (weaker dynamics, for example). As for Paul, he may be a nice guy in person and he certainly looks and sounds like he really is, however, when it comes to business he’s just the same: he mentions strengths of his designs, keeps silent about weaknesses which he will care to mention only when comparing to something better he has to sell. So with all that stuff it’s usually ’we improved something but we also made something worse on the way, however we won’t tell you what got worse since we need to sell, you get to figure this out yourself’.

Anyway, I agree that Paul’s admitting that an expensive AC wire made a huge improvement on his best power plant design tells much about the imperfection of this design, but also about the failure of this design’s primary goal: which was to re-make the AC and make it pure. If AC wire for its input power makes a huge difference there’s no way this goal was ever met. It still doesn’t mean it’s POS, but its marketing certainly is.
