In Reply to: RE: Modifying capacitor leads posted by banpuku on September 13, 2016 at 08:02:52
Dear Banpuku, I don't know if you've read the further discussion toward the end of this string, but I wondered whether you are comparing the originally specified 2.8uF capacitor, of whatever type, to the modified 4.7uF Clarity MR, or whether you have compared the very same 4.7uF Clarity capacitor, with vs without the modified leads. Since you are an experienced guy, I would tend to assume that the latter case holds true, but can you confirm? Thanks.

This is to confirm that I compared the 4.7uF Clarity MR to the very same 4.7uF Clarity MR with new leads. I still contend that I hear much better dynamics across the board. I am happy with the tweak and may try it in other places as time permits. Hope this helps.

Is there a reason you went to this cap? Versus the OEM 2.8mfd one.
Thanks!
To be honest, the amp came with a 2.2uF cap that was not a super high quality part. Call me crazy, but I believe in the so called "high quality audiophile" caps. I did not have a 2.2uF cap on hand. I only had a 4.7uF. So, I went with the 4.7uF and liked the sound. Now that I have changed the leads, it is definitely staying in the circuit; at least for now ;-)
Now, what will be interesting is the coupling cap in the circuit. It is a 0.47uF. I have 3 very nice caps to choose from: Jupiter Copper Foil, Russian K40Y and Duelund Cast PIO. I am currently using the Jupiter Copper Foil. Very very nice cap. Well balanced, very good dynamics, very quiet, black background. I will try the K40Y and Duelund and report back to AA. Should be a fun experience.
"To be honest, the amp came with a 2.2uF cap that was not a super high quality part."
In your electronics experience, What makes the old 2.2uf cap not a quality part?
In the circuit application, that of a screen grid bypass capacitor, what level of capacitor quality do we need? I mean what is the cap doing in the circuit so we can choose an appropriate capacitor technology.
Have you compared the engineering specifications of these "high quality" audiophile caps and parts to the standard commercial versions?
The real problem here is that there's no mention of those things that we know are required for a valid A-B test. Lacking that, these claims are really no different than a thousand other things people think they experience, when in fact they're merely being fooled by their own humanity. Do you know, almost every time I wash and wax my Vette, it gets faster. Sometimes it doesn't get faster, but it idles more smoothly. Or the transmission shifts more crisply. Or the AC blows colder. Ad infinitum...

Hey! When I clean the windshield, my car feels not only faster... but like it has a bigger interior!
Odd how the brain works.
it actually seems to look better.

I've found that 140 mph or higher in a heavy rain will cause a violent enough atomization of the rain drops to clean off most dirt. Not so much for bugs, but the sun will bake them off usually within a couple years. :)
