  Could we start our own Cap sticky ?? Stating ones experience with different caps and applications may be very helpfull.

I don't think you can beat the AC thread for the amount of info in it. So here's a link

Another infamous cap test on the net, from Tony Gee in the Netherlands.

http://www.humblehomemadehifi.com/Cap.html

I like Jantzen Superior Z, and Silver Z, good for the money, well built.

I am interested to try Scotty's suggestion about the solid polymer caps.

I'd go for some Clarity MRs if I had a special job like a nice tweeter.

The clarity MR work very well in coupling positions  :thumb:

  We can talk about our cap experiences here. The shootouts are interesting.  Our hands on experience is what I'm looking for on AN. Not a dealer of caps.

OK, then lets talk teflons.

I tried the Russian FT3 teflons as .1uF bypasses on both my speaker tweeter circuit and as bypasses to coupling caps in my phono stage and CD player..


This cap is exceedingly resolved like only Teflon caps are. After living with this cap for a long time, one has to marvel at its consistently musically-revealing nature and tonality. It doesn't wear its detail resolution on its sleeve, yet when one chooses to listen for it, the extension is impressive as well as actual detail and airiness without obvious glare.

Is it as good as the Sonicap platinums (no) or the VCap's (no)? Those are both a bit smoother than these FT3's, but they are also priced 4-5X higher.  Does it have good bottom end extension? No, it is adequate but not as good as many more basic caps like Sonicaps or Multicaps if you are going to use it as a single cap replacement instead of a bypass. I tried the FT3 in my Hagerman Piccolo step up and it was not a good match with this tiny signal. I reverted back to a Sonicap II which was much more fluid in that position all by itself. I also tried it as a bypass for the woofer caps in my speaker, and that was a mistake. It seemed to shift the crossover point higher which caused a mismatch between tweeter and woofer.

Over all, and for the price, these are a no-broainer. Easily available on e-bay you can buy several and try them out for little cost. The shipping might take a month to reach your home from the Ukraine or Russia, so make sure to buy enough to use elsewhere to avoid that extra cost and time again.

Oh, one more thing. It seems that stringing teflon caps together from one component to another to another can result in a too much of a good thing problem. Used in the source and speaker, it might be just the ticket, but used in the source and the preamp and the amp and the speaker it could easily sound cold and analytical.

  Bob, have had similar findings with the V-cap TIO Teflons. They can take over if too many are used. Recently orderd a pair of Dueland Alexandra caps as well as Audio Cap PCU to try in amp. Now there are two V-caps at both coulping positions. The only two caps in the circuit.
  My thought was to use the V-cap in the preamp instead. The cathode follower to be exact. There is a frankenswchwartz combo of a Dayton there now. I belive almost anything will out perform the Dayton.
  Time will tell.

For electronics, I'd take a good electrolytic such as Nichicon FG over Dayton film caps, Dayton are awful in electronics.

  Thanks Face. I just found out the the original coulping cap  used was an Audio Cap Theta. What was this guy who had the Pre before me thinking using a Dayton ? :duh The coulping position is to the cathode follower. Tube is an RCA 6GK5.

A person I know who was asked to fix a $10K pair of speakers with a broken crossover showed it to me - nothing but electrolytics and iron cored inductors.

Thanks

I would be interested in hearing from those who have experience with the Duelund Alexandra capacitors and how they might compare to some of the other capacitors out there such as the Mundorf, Clarity, Jensen and others.
