If one eat, drinks and sleeps car accidents for 40 years I would think that person can remember details way better than the average citizen.
The overall 1/2 db amplitude level difference isn't very consequential when trying to remember things like overtones and separation.
You just saw the Mona Lisa. Are you going to remember or care if it was with 100 watts or 101 watts of light? No.

There was a pair built each way. Each unit matched it's mate. Changing out the electrolytics removed the difference. Others have built variants of the audio power amplifier and seem to find it an acceptable performer particularly as it is only five transistors with two used as current sources.
These days I would use more parts and expect better performance.
Doesn't answer my question, no postmortem, tear-down, analysis, no valid conclusions.
Don't know who dismissed your system.
But that's a lot like being in a video forum where people are discussing the subtleties of various 4k displays and you come in and say that your NTSC Sony Trinitron is all you need?
Hope you don't take offense, but that's more or less what you are saying.
Or, it's a high performance racing car forum and people are talking about small suspension tweaks, and you refer to your Lexus...
...the point of reference, AND experience both count.
_-_-
Again, if your point of reference is shall we say "limited" then the conversation that revolves around "angels dancing on a pin" seems ludicrous. Which is more or less what you keep saying.
Of course the "angels dancing..." discussion IS ludicrous.
See my post just before this for a good point of reference.
And remember, all those wines taste EXACTLY THE SAME if the % of alcohol and pH are the same, RIGHT??

Ka-ching!
Ed, pleased that you have reported this.
It would be neat to see if the sonic differences did show up in a "null test" or a straight up FFT, THD or IM.
Don't forget to do a null between two "good" units and two "bad" units to show the deviation.
But, folks who are skeptical, this is by no means a unique experience - at least not in this part of the globe. Happens all the time. And, yes, it would be useful to determine IF the differences can be discerned via our usual test methods.
It happens - with or without a test.
_-_-
All units bench tested for distortion after assembly. On 18&20k IMD all the same. Now as we rarely seem to communicate do humor me and let us see if we communicate on specifically what you would like to know.
Is that all? We're back at the "once everyone saw the difference it was always obvious" for the n'th time, but no measurement showed anything. Try harder, aren't you curious?
No careful measurements showed a difference. But not unexpectedly it had nothing to do with steady state distortion. It had to do with the ESR, ESL and other properties of electrolytic capacitors. I have covered the differences before. Not at my office so I can't post pretty pictures.
When I hear differences I do try to measure what is causing the differences.
Actually need to buy some more test equipment to track down some interesting issues that have poked up their nasty fangs in my still incomplete power supply article!
No, I don't care. Zoom into the hair-challenged guy's ipod to see how many
rows were in front of him. Pearls before, no, I won't say that. I happened 2b1
of them.

Google Picasa gets worse and worse. Zooming seems not to work any more.
But I like my pic of Apollon doing a selfie.
Ah, nothing works as it used to.

Me either, with the layers of assault weapon proof glass. OTOH you can touch the "Winged Victory" as you walk down/up the stairs. A great place to stop and contemplate weather we are coming or going.

Sorry, I was there in the winter 1971. No stupid pyramid in front, not nearly so crowded then and it was free to get in.
I assume that is your attempt at humor. The self resonance of capacitors is well known. What is not as well known is that axial electrolytics have lower self resonances than radials of the same capacitance.
So that's your job, simple due diligence to know what works and what does not work or figure it out.
Eddy current Capacitors! In the 90's I remember seeing a schematic with large value electrolytic caps tied from plus rail to minus rail near an op amp. I asked an EE back then and he said "That is to cancel out eddy currents"
Can't find out much on the WWW.
Can anyone shed some light?
