Teflon Caps Synergy
« on: 20 Nov 2008, 03:53 pm »
I have an Audioprism Mantissa tubed linestage and have upgraded the caps to teflons (Chris V V caps) amazing sound and very revealing

I'm now thinking of changing the caps on my dodds. i'm looking at v caps once again however the cost and revealing nature of these caps may become  "too much of a good thing" and perhaps I should look at a similar quality cap that errs a bit on the neutral/warm side of things 

Anyone have experience using different caps in conjunction with Chris Teflons
i'm in process of gathering information at this time and in no hurry to make any changes

I would suggest getting some of the inexpensive Russian teflon's on e-bay (or look at the group buy thread on the Hagerman forum). Try these as bypasses to the existing coupling caps in the Dodd. You may not have to replace anything else.

They are physically large though.

Enjoy,
Bob

Thanks Bob

Would these have their own signature sound if used in this configuration

Nope - teflon's in general are just so without sound that they let it flow through. However, that being said ...

If you put too many in series with each other you will get that slippery teflon-like sound. I also found that using them as a full bandwidth coupling cap bypass works great, like in my phono stage, since they primarily affect the treble. Nice air and transparency without adding any glare or upper end forwardness.

They did not work well for me when I tried them as cap bypasses in my speaker crossover for the mid/bass drivers. The mids were too forward and unbalanced there. But they were wonderful on the treble crossover caps as bypasses also.

One other thing, be careful on your amps. You may find that they unbalance the top end. It will still be smooth and extended, but it could result in too forward a presentation if you use them on every transistor. I suggest trying a little at first rather than a lot, maybe one on each of the + and -, just at the ends of the rails where other smoothing and supply caps are located (I don't know your amp's config so I can't say for sure what is appropriate).

Some people also say they work great as bypasses to power supply smoothing caps, but I don't know. They are rated at 600V and so should be OK, but they are film and foil and not self healing if there is a problem and you could lose the component to a short. Your choice and your risk.

Good luck,
Bob
