Well Mr. McGowan answer is just too simplistic for a company selling what equates to luxury cars for audio. Again their whole business model is predicated in faith. Believing without evidence. To start, Mr. Paul McGowan, I could not find a bio that tells what academic preparation he has. Same goes for Scott McGowan which lists a Bachelor in arts in Linkedin. So your are dealing with 2 people that are in the tech business but don't have any formal preparation - at least academic - in the matter.
So what do they sell? They are selling you gear that may be SOTA (because they hired engineers to make it), but in reality is what they think sounds good. All they are saying is its sounded good to us, believe us - faith again - so you should like it too, because we did. In the process, they ask for $14k on an amp. its just that simple. We should not be surprised in any way that there is no measurement on any the cables, its just in which we can make money on.
The desire to make money is intrinsic to what they do, and who can blame them. Its 1986, I bought a Magnavox CD player at a reasonable price, since CD players were still a bit expensive, $230 was a large chunk. It was a rebranded for the US Phillips CD204 in black. Made sense since Magnavox was the Phillips brand for the US. So a few weeks after my purchase they opened a new Hi-Fi Store that carried PS audio. Wow, we needed to visit. So we went in for a visit and a listen, I see a rack of audio gear and see a familiar face. It was my Magnavox CD player with a different face plate with the PS Audio Logo being sold for $959. Its so funny, they still sell them second hand, search for the PS CD1.They had to use a rack mount plate in order to attach their labels and make it different, but we all knew it was the same thing, same door same, same mechanism same all. So back then they had those who did not know dupped into $600 or more profit.Thats who these people are. Many adjectives fit the description, you go ahead and pick yours.
What!!!, at that point I knew to be careful with so called High End great and to be really careful with all they claimed and said. So I come back home and realized that I had a PS Audio CD player connected to my $150 Sansui received bought from the J&R (still miss them) catalog. What an upgrade, I now had a PS Audio CD player. jejeje
So all we can do is be curious and educate ourselves. This site does a lot for that, all we need to do is make sure that directional RCA is plugged the right way... just kidding.
