This capacitor....
E36D101LPN103TC92M United Chemi-Con | Capacitors | DigiKey
Is about the same size and value as this one.....
MAL210119103E3 Vishay BC Components | Capacitors | DigiKey
But this second one is a lot more expensive. I realize the more expensive cap has a longer life span and I suppose that explains the difference in price. But for a power amp power supply is that the only real difference?

Yes I'm open to that. The better the power the power supply the better the sound. The audible difference is not subtle.
If you read the whole datasheet, United Chemicon caps I've looked up have a worse ripple spec at end of life than Panasonic, nichicon, rubicon, vishay. So the 2000 hours is probably worse than that.
If you want to save money, buy snap in caps instead of screw terminal caps. Put them on some nema CE board, glue them down, drill holes, solder to terminals on the bottom. Mount board on standoffs. You can also save by paralleling two 4700 or three 3300 instead of buying 10000 uf. Costs more time. I don't skimp on service life, I put parts store front shelf caps 4 times in my original power amp and that is too much rework.

Right, if your open to it, otherwise no difference in sound.
Audiophool BS. Learn how a power supply works. Then learn how your amp uses it.

I know this will be frowned upon, but I have to say for someone that's wants objective reasoning... To say capacitors that measure completely different, one should expect completely identical results... And to be so anti-science to attempt unbiased trials... You're an egotistical quotient-challenged luddite.
Also your analogy is bad. It's actually like you don't know what the experience of falling will be if you wear various wind catching devices like squirrel suites. This is because we know both capacitors will supply capacitance in a normal electrolytic manner - your analogy would be applicable to wondering if the capacitor would act like a capacitor or not.

^ tis true.
I marveled how these small differences can be perceived so easily auditorly.
So you should be able to explain how these parameter effect SQ? They can all be modeled including leakage.
Completely different? No. Some secondary parameters that dont matter differ. And your attack is unwaranted and rude.
Yes they can be modeled, and there will be an effect in the model, too... Why wouldn't it be so?
Oh dear, not this again! Plus, the dreaded 100% Blind ABX tests into the bargain!

Well Chester, your opinion is quite clear and obviously, you don't find any difference between good quality and poor quality power supply capacitors in anything, power amps included, and 25 years as an EE in the recording industry/studio is enough confirmation that you're right and I'm just another misguided person/stupid fool (I do try to follow this sites Rule No 1!) that promotes expensive BS.
I think I understood your comments correctly, yes?
Now, everyone's entitled to their own opinion, but could you be a bit more polite about expressing it here.
You remind me of Stuart Yanager, another "BS evangelist" that used to brighten up our days with his absolute convictions about "Audiophools" and their expensive habits on the 'Snake Oil' thread.
Good morning Jeremy, hope you're "doing well"
