In Reply to: RE: What does this prove? posted by Duster on July 26, 2018 at 21:21:22
I hesitate to emphasize this because you'll accuse me of attacking you, but you missed the point of my post. I believe that it sounds better. You certainly have enough experience to know how to evaluate it, and I don't doubt that at all.
What you did not accomplish, but one of your claims, is proving (or demonstrating, if you prefer that word) that a higher voltage cap sounds better than a lower voltage cap. Since you changed cap types, there is no conclusion to be drawn regarding higher vs lower voltage capacitor. If you had compared the SAME capacitor with different voltages, then we would know if voltage capacity of a capacitor matters.
I know how the forum works, so no need to lecture me on that. I don't need proof that you got better sound. But even you don't know exactly why that happened because your experiment contained two variables, and none of us knows which variable was the effective one. Was it the FW, or was it the higher voltage?
Got it?

In fact, I believe it's possible that the difference in sound is due to brand or type, and it may be that using a 16V Nichicon equivalent would sound even better, based on the concept that for electrolytics, you want the capacitor to be maintained near maximum voltage rating, so the plates are near fully charged. You're coming at it from a different angle, but we are suggesting the same thing. And it would indeed be an interesting thing to check.
Okay, Lew. I'm considering the 16V Nichicon FW 2200uf capacitor. Perhaps you can tell me what to listen for in terms of improved performance, and whether it might be something to hear right-off the bat, or if it will take time for the new caps to settle-in before anything notable might be heard.
I don't mean to be facetious when I suggest that you listen to find out whether the 16V, 2200uF Nichicon FC sounds "better" than the 50V, 2200uF Nichicon FC. Only you can define "better". I am curious myself to know what you think.
Therein lies the rub, Lew. When there is no clear reason to go against the idea of, "if it ain't broke, don't fix it", it's a gamble to keep soldering and un-soldering electronic parts on a circuit board. I believe the improved performance already accomplished via the upgrade from the Panasonic FC to the Nichicon FW regardless of the voltage rating is profound enough to leave well enough alone, at this point.
Another thing to mention is that this is the second of the same make/model audio component I've worked with, and the manufacturer actually changed the two stock 16V Panasonic FC capacitors to 10V Panasonic FC capacitors, which is in line with the notion of being a better option for a +/-9V application. In comparison with the first unit that featured the original 16V caps, the unit with 10V caps sounded rather dull and less dynamic with weaker performance at the frequency extremes, and a more restricted soundstage presentation. The 16V caps while sounding more euphonic, were more musical in nature, with a bigger bottom-end vs. the 10V caps. The impression was that the 10V caps sounded "cheaper" in terms of performance from a subjective POV than the more full-bodied 16V caps. Upgrading the 10V Panasonic FC capacitors with the 50V Nichicon FW capacitors provided the same improvements for the second unit as it did for the first unit.
I'm concerned that while it might be be more correct to choose the 16V Nichicon FW vs. the 50V Nichicon FW, I'm not convinced that I should expect the 16V Nichicon FW to actually sound better for the particular device simply based on a concept that is not widely known to be an audiophile rule that should always be followed. It could be possible that my hunch to choose the 50V Nichicon FW might simply sound better to my ear for the application. In this specific case, I don't wish to be an experimenter when the final results are not clearly predictable.
I never claimed that the reason why the 50V Nichicon FW sounds clearly superior to the 16V Panasonic FC is due to a higher voltage rating. If you would stop trying to find fault and denigrate my credibility as a poster in AA, you might have a clearer perspective of things I might say. Otherwise, I have no desire to have discussions with you other than defending myself when you misrepresent my posts and act like an enemy. There is no rule in AA forum politics that requires interaction with those who act as bullies, trolls, or enemies.
I wrote as the OP of this thread:
"I'd like to make sure that a capacitor upgrade involving the same microfarad value but with a higher voltage rating is suitable for this particular circuit design"
Some folks clearly opined that it is okay for the particular circuit, while Lew posted the notion of choosing an electrolytic capacitor with a voltage rating that's closest to the operating voltage, unlike the notion of choosing a substantially larger rated voltage film capacitor. So I understand the premise. The only matter that I had issue with was the statement that claims the 50V Nichicon FW would not be a worthwhile tweak vs. the stock 16V Panasonic FC for the application.
Lew's opinion of:
"This is contrary to the theory as it applies to film type capacitors. So, I doubt you'll be better off with this tweak."
My response was about not being better off with this tweak:
"From a sonic POV, the 50V Nichicon FW sounds clearly superior to the 16V Panasonic FC for this application, Lew."
It's really quite easy to understand what I've said within this thread if a reader has an open mind.
