Isn't it written on the label on the HiCap? It used to be a million years ago.
I'd also suggest that with a non Naim power amp, you can take the signal from the 82 itself I think.
Flashback sales should be able to sort you out with a good interconnect at a fair price and i think SoundStable on Ebay do one as well for less money, but still using good wiring and plugs.
If you wish to make your own, I'd suggest PM'ing HiFi dave if he doesn't pick up on this, as he's a Naim dealer and has some of the "dealer" manuals....
I can't go on and I can't go back, I don't feel so matter of fact,
I tried and tried to make good sense, What's the good to try it all again?
