Dueland CAST PIO

Ssos101,
I believe you made a very wise decision,there should be no second guessing as the results will justify the additional cost.Congratulations with your new Vapor speakers.
Charles,

Great.....super decision! Let us know after some 50 hours of break in.

I totally disagree.i have been modding Loudspeakers as well as electronics 
for 15 years. I just replaced the Mundorf  Supreme ,and silver oil with VCap OIMP
caps very nicely balanced but need a solid 100 hours to start opening up.
up to 400 hours to fully runin .the midrange now is much more liquid
the a Mundorf  Silver oil are nice but lacking in Bass and not as deep in soundstage depth vs the VH OIMP caps.
I would rate these a 11+ 
now if using a VAh CU teflon bypass then is as good or better then Jupiter Copper, or Audyn true Copper. The Mundorf cast are a 15+ Top of the hill hands down . But 4-5 times the cost for 3% or less .if you have money to  spend then do it. personally A The  Jantzen Copper inductors are excellent and as good as  most any. For Resistors the Path Audio are The best out there for Loudspeakers 
yes betterthen Duelunds cast  . I have done several speakers and under 1% total distortion  and are constant under all demanding conditions. One more thing with VH their matching of all capacitors to under 1% combined with these resistors 
precision at its highest No other company has tested this close for a  Loudspeaker system. For  most Audiophiles my recommendations would be 
considered  Excellent ,but as a Audiophille You can buy pure Silver duelund caps 
and spend $20,000. It is only money Right !!

Duelund resistors are weird. They have some sort of thermal coefficient built in they call a good thing, but it only works if the speakers heat up to match.

Audyn TC caps are outstanding bypass.  Right now 0.10uF at PE are running $16. Pretty good deal for performance.

@audioman58 Have you tried Mills resistors?

Best,

Erik

I was asked if I have used Mills resistors .Yes many times in the past . Please keep this in mind the higher the order crossover the more critical it is magnified. For example if you have a 5% resistor 
it can vary up to  Ten if you have other parts 5% or more a speakers Channel can vary by more then a 1/2-1 db which is clearly audible. I had found VH audio  OIMP cap with a V CU bypass and option to match all caps to within 1% or less to complement the Very accurate Path Audio resistors which are smooth and Very detailed and total distortion under 1% on average . In my Salk Bud Fried Transmission towers. It is incredibly accurate as well as a deep liquid midrange and detail across the board. My new favorite caps with bypass for roughly the same as 
Mundorf silveroil and personally like better then even their SGO caps.  Well worth tchecking out.and these and Path resistors take 
3-400 hours to Fully runin .
