'The new Jupiter copper foil is the trick. $400-$600 for the set of two instead of thousands!'
Hmmm.
Had a look at Parts connection. 1uf Duelund RS - $127.00. 1uf Jupiter Copper - $115.00
I know someone that sells both Jupiter and Duelund, as well as builds speakers with them. And those prices reflect exactly what he tells me - lower values - Jupiter wins hand down - price/performance ratio much better. Higher values - not much in it price wise.
Regarding Duelund resistors - forget tolerance - their big advantage is the negative temperature coefficient so that music doesn't become compressed as it gets louder. I have heard the difference and its clearly audible.
A GTG is being talked about out my way where there will be a comparison, in exactly the same speaker and crossover, of
1. Duelund Cast
2. Duelund VSF Copper
3. Duelund RS
4. Jupiter stacked aluminium.
5. Jupiter Copper
If and when that happens it should prove interesting.
Thanks
Bill
