And why would you care about it? His USP is only a rubber strapped Qz and unlimited budget for 0.001% ladder resistors and for "some exotic" tools to measure -160dBc at 10Hz
Please go back re-do your 101 RF class.
Btw, do you know where this is? I must join you. Same, Andreas orders. Yes, ssht, he found me too. I failed all RF classes by him... history included. Also I have same attitude problem as you: cannot stay humble in front of him.
P.S. Gerhard, sorry, did you told him about Time-Nuts? Why? Yeah, hmm, I know, we all do mistakes.

Why not. It's helping others to see through the ubiquitous marketing fluffs. Reading this forum should be informative for those who want to learn.
I can only find Hans Polak's on 3m cables, can you direct me to Markw4's?
I'm not surprised if someone can hear the difference between cables. One of the top mastering engineer, Greg Calbi once showed me off his patch cable collection used for coloration he said. I'm a lucky guy who can't hear any difference between cables, therefore no need to spend 10K for power cable.
But you still built amplifier with THD 0.0001% at all audio frequency and all level below clipping.
I doubt you can hear the different with amplifier that have distortion about 0.1%.
I would suggest you refrain from supporting those who engage in shill act on this forum.
Doesn't mean everybody will be able to tell any difference between one of his design with 0.01% and another with 0.1ppm THD regardless. But given current prevailing attitude, the majority will choose the 0.1ppm even when priced considerably higher.
Only in your mind, never in reality.

Right. The scientists proved that human perception is extremely easy to be biased, and if "0.1ppm" is a very positive information for someone's brain, the sound he is listening is actually "better" with this information.
It's not our business if he can really hear it or not. Why we would bother this happy audiophile?
On the other hand, if someone believes 0.01% and 0.1ppm makes no difference, he can't hear any difference forever because of his belief, a very strong bias. Keep believing it, it will save a lot of time and money.

I think it is not his design, but Edmond Stuart design (simulation). He made the PCB and built it.
I thought the purpose building the PGP amp was clearly stated on the web site. It was a pure engineering challenge, without any assumption of SQ performance.
I strongly believe that anything under 0.01% distortions is not audible, there are other parameters beyond distortions that can make a difference. I also strongly believe that if there is anything proven as being audible, it is then (easily) measurable. Sorry, but markw4’s, jam’s, andrea’s, and their kin’s, reports are anything but “proven”.

I do not care if anyone can hear distortion below 0.01% and I'm not feel intimidated if someone claim it.
But I appreciate if someone make better design although it is below hearing threshold of average human that scientist knew. So, I appreciate Andrea's oscillator. It proved by measurement. I'm not jealous.....

I can understand your sentiment about the others, but I have not seen Jam anywhere making any pretentious statement he can not back up. Kindly point to one single example of Jam doing so.
