Bill, I agree! I don't think anyone wants to spend big bucks on caps! But if a particular cap has been tried and noted to make a better improvement audibly, then it may be worth spending the extra money. Personally, I have a limit to how much I am willing to spend! Others may be willing to spend more! If you don't mind me asking, what brands of audio components do you listen to? Have you tried changing out any caps in your system to compare rather or not it was better/worse/same?
Sounds very interesting and tempting!
I have located a source to purchasing the CDE's. What values did you try? They are available up to 4.7uF. I would need a value of 6.8uF, so I could parallel a 4.7uF with a 2.0uF and perhaps tinker around with some .1uF's for a bypass. I wonder what the Audyn Copper Foil cap .1uF would sound like compared to the Vishay? Hmmmm!!! Decisions, decisions, decisions...lol
This is what I used. I local parts supplier was selling them at audiophile prices. Expensive but cheaper than a lot. The thing is that I found an OEM supplier and asked for samples, but they sounded different. After some tests proving they were different, I was sent a few more different caps to try out. Primarily different material and different form factors. I did finally find one that sounded almost indistinguishable and measured similar.
I was using 6.8uF at the time trying to find a smaller form factor than the Mundorf gold silver. If anyone wants to get some to try out, I can see how much there is left of the lot and also the price.

I am curious as to why your OEM supplier sent caps that appear to be authentic, but yet they sounded different? I think I would find another supplier..lol I would be interested in trying these CDE caps! Perhaps you can let me know a price, and if possible, test them to be certain they are the correct ones! 
Thanks Soongsc,
I would like to try out a few (4) of these large 6.8uF, or larger 10uF, if available - I have the ideal spot in the feedback network of my Cavalli headphone amp!
I was just about to order some 0.1uF/600 and 0.22uF/600volt ones from Mouser, so if you have an excess of these too ....

I think if you want the CDE branded device, it is best to get it from an authorized distributor. I went to an OEM because the CDE caps here are very expensive as well. I was looking for a similar sound quality at lower price for a specific product. So I am not claiming the ones I have are CDE, just that I used Mundorf and CDE as references in the selection process.

Hi,
Has anyonne already tried the Silmic II 100 volts rated in the medium department
(in+--+ serie configuration to make it a bipolar). It's not given a lot of values headroom... but how does it sound ?
A question about Mylar caps : is there some metal in the mix of the dielctric ? Like the MKTs... Or is it the same stuff ?

That's an interesting idea from a couple of views - how do they sound as a signal carrying capacitor? I've never tried that.
I'm always looking for the bipolar electros (usually the green Nichicons) I didn't think about using the common Silmics arranged in this way and I've got a whole lot of them
Ah, 'the penny dropped' (sorry about that!), I could also do this on the output electro caps on the headphone amp instead of the usual 'monster bunch' of PP caps (looks like bananas!)
I must try this - you are onto something!

In the electronic stuffs at DC output they are good while some Black Gate like the N serie were better ! Both much better than the green ES Muses from Nichicon (often too thin tonal balance and a little too climby and mid deeped from a subjective point of view)
But here I realy ask fo speaker filter as Tony's experiments : at least for the mid in serie where high capacitances are often wanted. I know some used Black Gate AC caps in speaker filters as well!
(at dc dac outputs, this Silmic II opposed serie arengement + // Aluminium in oïl from Amphom to help the highs and mid is Something to try if you have some on hands !

MKT and some other formulations of plastic including Mylar appear to perform very similarly. And all perform better than electrolytic of the polar and bipolar variety, when tested as audio signal filters.
Polar back to back are nearly as good as bi-polar.
I have used polar in back to back and used bipolar alone and used front to front in parallel with back to back using 4 polar electros.
All three varieties seem to my ears to perform as well as each other in DC blocking duty where the AC signal across the electros is virtually zero.
If there is any effect due to Dielectric Absorption (DA), then I can't hear it.
I have even tried this at the input and still I can't hear any difference.
Note I differentiated between filter and DC blocking duties !!!!!!!
In a crossover the capacitors are working as filters. That is a very different duty from DC blocking. The highest quality capacitors, like polypropylene, Teflon and polystyrene have the lowest distortions when a high AC signal is across them. Then the other plastics have a higher distortion. The electrolytics have the highest distortion for this duty.
You should be able to hear this fairly easily.

quiet difficult to understand sometimes ! For instance Kef used Low Loss electro bipolars with tang loss factor of 5 to 10 % if I'm correct (My Kef 104/2 ref) with some "normal" bipolars !
I assume these low loss electro bipolar have close datas than the MKTs which are not in the same league than the MKP, styren or teflon you pointed out.
in the Boston main Acoustic speaker I have they // 0.1 styren (MIT RTX) with large amount of electro chemical... often see in the trebles but also here in the mids ! I surmise it was more for the HIFI magasines and reviewers than for an effective result in the mid area !
Is there a question of group delay (don't know f the word is corect in English?) with capacitors and filters for time behavior ??? I.e. : MKPs should not be in some filters a good swap for electro bipolars or MKTs ????

There was a very detailed technical study done years ago that bears the above poster's last statement. It can be found on the web still, I believe. It was called "The Sound of Capacitors".
