I don't think he was the owner.
I spent years in the seventies working in audio and electronics and the great , overwhelming majority of the folks I worked with, had learned nothing at all. Whatever they thought they knew came from product introduction meetings conducted by manufacturer's, usually with pseudo science presentations, and mentions of the sales spiffs, to be provided. Even back then, the industry was starting to smell so bad to me, that I went elsewhere.
Interconnects and cables are basically snake oil. ( I have a
very large roll of 12 gauge copper stranded speaker wire , a VERY expensive STAKON branded crimping tool [as used in medical and aeronautical applications] and the matching Stakon (or 3M)connectors and several varieties of silver circuit board paint. There is nothing that can audibly improve a speaker cable made with these materials.) We shall have to agree to disagree on this subject. Your ears are a totally unreliable measrement tool. However if you think there is a difference and you LIKE this or that piece of gear (or Shakti stones or trestles for your speaker wires , or you want to spend $1000 on an RCA cable) knock yourself out.
I do not feel the need to try out every piece of bullshit that the very creative audio marketing machine spits out.
Audio Science Review has lots of reviews, showing no improvement, of many things, including cables and interconnects.
When I was at Axpona in 2019 this guy actually grabbed me and pulled me into his booth. (I am glad he didn't actually have a hook!) Since it APPEARED INITIALLY to be some sort of technical thing I gave it about 20 seconds.
https://add-powr.com/ I never listened to it, and I don't need to, and wouldn't waste my time. Furthermore, I would never ever do business, with a store that sells a product like this.
Painting the connections with silver circuit board paint is something that I do, but I have no belief that it improves the sound. But it is easy to do and I just do it. It's "better". But it is probably snake oil too.
This isn't:

Often when there is a great deal of audible difference, there may be some or other incompatibility or incorrect operation or even the source material is poor. More often the it is because the test is not blinded, and levels have not been matched or someone is attempting to do an A B test where it takes too long to switch. There are a lot of scientifically established facts that really are a waste of time to argue about. There is absolutely positively no need for interconnects using precious metals of any kind. There is no need whatsoever at any audio or even ultrasonic frequency (ie 30kHz) to use Litz wire for anything. Not even phono cables. It is a fact that vacuum tube amps have higher noise distortion than solid state amps. That is great for guitar amps. For stereo amps not so much. ( I have heard that it is possible to have very low distortion tube amps , especially if you use solid state voltage amplification but have not ever seen a test of an amp like that) Of course the folks that bought McIntosh will be happy to sell you a tube stereo amp for $5000. On ASR somebody just posted a teardown of a Carver 275 tube amp and it wasn't pretty. Go look at it.
