Choice of capacitor

coupling caps in a couple single ended amps.

I have the jupiter copper wax in pre amp and was thinking jupiter HT to balance the sound whats your opinion

Copper in Pre and HT in amp

sounds like a mighty fine plan to me

In our direct comparisons comparing the V-Caps Oil to Milflex Copper - to Jupiter Paper, Jupiter Copper - the basic V-Caps Oil out performed all of them in our directed heated triode 101D tubed DAC, 6SN& based preamp and hybrid 6SN& based power amp.  We have used V-Cap Copper - which we really like and the newer caps they offer all to our satisfaction over the other capacitors.

We sound the Jupiter Paper to be muted and lifeless,  The copper better but no real out of the box sound, the Milflex much better but even they are getting expensive and the V-Cap Oils to just sound musically better and more open sounding.  Move up the VG-Cap line and they get better. 

Happy Listening.
