dc10audio use Duelund CAST capacitor ?

Each capacitor is hand built and sold in very small quantities.

I have been very lucky and have been privy to capacitor comparisons done at a speaker maker I know. He has 4 levels in his speakers - Erse - Erse bypassed with Duelund VSF Copper - VSF Copper and Cast. You can easily hear the difference with each level - its an increase in speed, clarity and naturalness.

I heard comparisons of two speakers both exactly the same except one used Mundorf SIO and the other Duelund VSF Copper. I listened to Patti Smith - Gloria with the Mundorf's - her voice was low, arresting and guttural - you go wow - but it did not sound like a normal female voice. Then the Duelund - it was not as arresting or as guttural, it sounded more recessed, you think its not as good as the Mundorf - but you notice its more natural and faster - things sound more life like. You go back to the Mundorf and you realize its false.

Forget the Silver - its a personal preference thing - some love Silver others like me don't like it - unless you really love what Silver does save your money and get copper. The speaker maker I know has checked it all out and doesn't even offer silver as an option - if you asked him he would build you one as a special order but at a much greater cost and you may not even like it - many, possibly even most, don't.

Regarding cost the Cast version of the speaker the manufacturer I know costs $13.5k. Expensive - yes - but there are many many much more expensive speakers out there. Personally I have not heard a speaker even close to that speaker regardless of cost.

Thanks

I love my silver IC and speaker cables, excellent tone and resolution. The
copper CAST is an extention of this quality. They are utterly natural and
realistic just as bill said.They took my speaker and DAC from very good to
simply a superb level of sound quality with their installation.You can't go
wrong with this wonderful capacitor. I see no problem using the copper
version with silver wired component s what so ever.Seems a good
combination to me.The silver CAST may be better but I''ll say the copper
CAST will likely out perform any other capacitor.

I have been using Duelund products since 2006. In that time I have tried VSF Cu, VSF Black Cu, Cast Cu, and Cast SIlver. Each time I moved up the Duelund line the sonics improved. When I finally tried the Silver Cast it was hard for me to get my head around the price.

When I finally took the leap I was well rewarded. Going from the VSF Cu to Cast Cu is a very obvious improvement. Going from a Cast Cu to a Cast Ag is as obvious.

Most associate silver with being thin or bright. My experience confirms this if it is stranded silver wire in a teflon dielectric. Duelund uses silver foil, this is why the cost is high because foil is expensive to manufacture, and it does not have any of these traits. I used Dulund silver on the LF first and the improvement was more definition in the bass, greater weight, and more speed. Notes do not hang longer than they should and have a natural decay. Going back to copper it almost seems the bass is bloated after using the silver.

I use Duelund Ag wire inside the speaker and this was a substantial upgrade. Check in with Volleyguy as I instructed him what I did and he did the same regarding the internal wiring. Our findings were almost identical.

I have Scan Speak Revelator drivers in my speakers. With the Duelund Xover and internal wiring they pair very well together. I call them the Denmark connection.

The one area that is not discussed that much is Duelund inductors. For me they are the real value in the Duelund lineup. You have not heard a black background until you try them. You will hear more ambient infomation with them in. They improve all frequencies. However, in the LF in series with the bass driver you will hear things that you never did.

The caveat with Duelund is their size. They are BIG ASS. If you are interested I have numerous Duelund caps lying around and can send a photo of them compared to a V Cap, Clarity MR, Jupiter HT, Mundorf Supreme Siler/Gold.
These caps are dwarfed next to the Duelund.

Irish65,
Your comparison makes sense, silver products are wonderful with proper implementation.The cost is too high for many of us but the copper CAST are within reach for more people. Just don't hear the silver version and you''ll be very happy with copper CAST.

Irish65, I'd love to see some pics of Dueland and other caps. Could you e-mail them to jeffreybehr(at)cox(dot)net?
