Duelund Tinned Copper Bypass Caps vs Duelund CAST, Jupiter Copper Foil, VCap CuTF

The only down side is space , just think around 2 inch long x2 inches wide 

and very dense maybe over a pound each , if you do have  the room  just run longer leads and a tinned copper awg 16 ,Jupiter makes excellent cotter tinned copper I am using this wire and Jupiters new exceptional value aluminum foil in oil ,paper hermetically seal caps I use these in my Loudspeaker purifiers these destroy the so called purifiers from Synergistic research at less then 1/2 the cost 

I  sold a bunch to friends in theU.K  ,I will put them on Audiogon next week.  

they rule clear up thetop end just connect to the speaker terminals.

@audioman58 Thanks, great input!  Very happy to hear CAST level sonics can now be had for a lot less money!

The tinned copper Duelunds are exceptional ,a bit more top end then just copper foil, and their oiled paper in a deep vacuum and same resin as the cast .

i have  in my coda CSIB integrated amp a 1UF coupling cap , I tried a .022 vhaudio Cutf great detail but 2d , used same .022 Duelund jdm silver foil oil very nice and open and smooth , just as a hunch I bought the Duelund1 uf coupling cap 

no bypass caps the JDM tinned copper  foil paper oil , it is Huge almost 3 x as big as theJupiter copper foil 1 uf , IHave pictures ,ihad to relocate it to the edge of the board below ,butWow itwas well worth it , I compared withtheWaay overpriced cast Duelunds 

guess what almost exact , same size ,weight over-a pound I would guess ,

just a bit longer vacuum and their silver thicker leads with cotton ,and the cast almost 150% more,$$  the jdm only go up to 2.2 uf  if youcan fit them ,the best capacitor out there period for electronics and loudspeakers  ,if  using for a bypass cap 3%  or less a great rule of thumb ,a nice natural detailed warm performance,give them at least 300 hours to fully runin, after 💯 + hours they start to open up nicely !!
