Dear friends I am interested to upgrade my caps in the tube preamp from Audio theta tin foil 3uf200VDC to Miflex1uf 240VDC copper foil what are your thoughts will reducing the value to 1uf affect the bass and frequency response or should I go with a higher value than 3uf  
I hardly ever check this forum any more but I did today and I read this entire thread.  And it reminded me why I don’t read threads here.  Same people arguing about the same topics, over and over.  Don’t you get tired of this?  You guys need to move on!
As far as what brand capacitors to purchase, the two choices for us were V-Caps and Audio Note.  In comparing Milflex copper to V-Cap Oils, we preferred the V-Caps.  The ODAMs are an excellent option and the Copper V-Caps are excellent but expensive.

Happy Listening.

I have a question, about, the cap located in this crossover. You know what's going on.

Can I use directional caps in this crossover?  Hooking the + side of the cap to the incoming  + signal and the - side (marked) in the direction towards the speaker + terminal? OR in the case of C7 where it is going + to -?

Could there be an issue for the amp in any way?

I'm not try to set you up either.. LOL I'm asking because I've used directional caps in crossovers (Vishay 160v) with wonderful results.

Actually one of the most neutral caps I've ever used other than Clarity.

I've found that resistors have a signature too.. I'd like to see some studies on that. 

The exception a LOT of boutique caps. Mundorf is about as colorful as they get. The exception being the little white Classic 630v..

What say you Mr cakyol, I was just wondering, why? Bi pole vs polarized, would it make a difference in a passive crossover? I'm cheap when it comes to 400.00 usd caps that are on the low side.. I'm a 4.00 cap guy.  40 cents is even better. :-)

Russian surplus PIO. 2.00 dollar special. Why not they sound really good?

What about Russian surplus, ANYONE? Who has used what?

Dear @charles1dad : "" So if a listener actually compared the Duelund CAST, VH ODAM and Wima capacitors and having heard them (In his components/audio system) found the Wima the least impressive he is wrong and misguided?

Wima is the only correct choice ? The other two capacitors are merely flawed, inferior, colored and distorted? It is totally irrelevant if the listener prefers the sound quality of the CAST or ODAM ? This preference is simply borne out of ignorance and lack of understanding? ...""

Answer to each one questions: NO, and NO ! but the colored and " flawed ".

Now, I experienced/first hands for years the " boutique " caps in my system and other systems and I " like " it what I was listened. Wima? no way that I thougth on them was a forbidden cap for me no matters what.

So: I was wrong? yes but the real issue is not about me or you or what I like or you like it or any one else.

The real subject is about caps and what they should do and what they must not do and the why’s it performs well or not. Tha’s why I share the first link in this thread that I was unaware of it when I started my caps thread looking for help trying to find out the: BEST NOISELESS SIGNATURELESS one, this is part of that thread title.

There I discovered WIMA/KEMET/VISHAY caps that was and is the answer for that cap thread title.

The discovery task was really hard for me because I was totally biased/married to boutique type capacitors. So I made efforts to be " unbiased " and started from " zero " with out my really big prejudices against Wima and the like.

I’m totally sure that with out that " unbiased " attitude I just can’t discovered what was in " front of me " for to many " follower " years audiophile attitude.

When I listened my first Wima through the crossover speakers what I listened I still have " present ": dullness sound with no " life ", my first thought was to forget about and return to the boutique ones but I decided to gave a few days not to the Wima caps but to my brain to " digest " that different sound I was experienced and thank's to that I started to learn what I was losting/missing with the Wima/Kemet/Vishay capacitors that existed in the boutique caps that I loved through many years and what I missed were its high COLORATIONS against the way lower colorations in the Wima cap.


@salectric , how many new topics available for any audio forum? Subjective vs. objective argument never ending and futile, as is the best whatever.
Tried the Russian PIO in a Latino clone Dyanco amp some years ago, warm, inoffensive, not top tier resolution, transparency.
