In some countries if you have no money in the Pocket you can pay with it....
Depends on who's willing to buy;
My wife is into handbags and shoes, I'm into audio...
She threatened me to throw out an ugly piece of junk and didn't want in the house that I refer to CRO....
Lol.... classic ! First buy the shoes, then only the speaker if you want to have any chance.... then make the deal with the hand-bag !
It was simplier before when we exchanged women with camels !
Poor world ! Now this is me who wasch the plates and coocking (better for the health of the family indeed !)

I've never dealt with camels
I never question the BOSSES shoe or handbag purchase, no matter what the price, I do know that she will buy on impulse on stuff that's heavily discounted or on sale. Today she bought some nice Coach handbags thats reduced 50% off and some nice discounted shoes.
As the saying "happy wife, happy life...
"I however haven't bought HIFI since the 80s, I went the DIY route, today it's hard to find a circuit concept you wanna build so I took the expensive route and purchased commercial, then the purpose is to improve on that with better components.

Try to get an AYA II 2014 DAC... from AUdial, it's still DIY but already developped; sounds awesome and you can do like me : construct it hidden in the toilett room at night ! (Wife believe I stay in WC a lot because porn magasines !... Nah, when your wife is pretty as a camel you don't need... the magasine I mean !)

Try a Jamicon 10K/50V with a // FC 1200/50V ... you may want reputt them
Always better to listen first before removing !
Some FM can be a little fatiguing in the high mids (sort of subjectiv odd harmonics : like), but not all : Some FC are smoother than FM...
Listen first means much more work.
no time to make it a project but i did measure lower thd with Muse BP 10uf 50V bipolar compared to high voltage mkp.
it suprised me.
so i read up on it and yes the mfg process for muse bp must have some magic.
i have many old magazine articles scanned in on capacitor tests. the voltage selection is a factor.
sort of an early effect, two opposed polarity electrolytic do not equal one true BP.
this also was found in testing.

BTW I find the old one very more musical than the new one they make today : I have many old green bipolar Muse from the 80-90s, took in second hand CD player : so very "breaked" : sometimes I find it better than even two Silmic II in serie reverse typology for DC blocking ! But find horrible the result in local supply cap despite what they wrote In Linear Audio mag.
I have never given much credence
to capacitor's effects on ' sound '.
HOWEVER !

Capacitors are audibly the least perfect electronic part. They all sound different,
despite having similar value/specs. I first found this out for myself in the 70s
when repairing and upgrading audio equipment for customers. It's no wonder
the best audio electronics have as few capacitors as possible in the signal path.
This includes film capacitors as well.

Are you saying that Jameco ValuePro (probably a cheap rebadged Chinese/Taiwanese generic capacitor like Samxon/Teapo/G-Luxon/CapXon) sounds better than a Nichicon FW?
It's possible, because FW is not an audio-grade cap, but just a general-purpose series which is roughly equivalent to Pansonic NHG or FC. It's OK in certain applications, but perhaps not very good in the audio signal path.
Electrolytics - Polarized vs. Bipolar
Electrolytics - Polarized vs. Bipolar
Gentlemen,
Just for info purpose: a question about these 2 lytics to be used as input capacitor, just before the differential pair. (I know any 2.2uF film cap is better than any lytic. This is for info purposes only).
Both are 2.2uF / 50V, but the Panasonic (bipolar) is lager than the Elna (polarized). Which one is better for that position and why?
The Panasonic was in the PSU of a TV. The Elna was in an Yamaha amp.
P.S.: both were made around the same time, 1990 (Elna), 1991 (Panasonic).
Thank you.

An externally hosted image should be here but it was not working when we last tested it.

Bipolar, no? And it'd be better to put 2 4.7uf in series.

If the amp has split supplies , bipolar
since there is no voltage to bias the cap.
Otherwise use polarized.
Read Bateman - adding bias isn't as good as a real bipolar cap for distortion
Section 5 shows with varying amounts of bias distortion does change on the polarized electrolytic, even back to back ones but it is still twice or more than the distortion of the bipolar electrolytic capacitor.
To qoute Batemen's summary:
" In every case the bipolar capacitor produced much lower levels of distortion than measured on similar value and voltage polar capacitors."
