Post Subject: Cable itimacyPosted by N-set on: 1/17/2013

I must say I've never came in to intimate contact with cables and avoid it untill I can, so yes all my arguments are theoretical.
By amplifying I ment of course voltage, not power and ass-u-med that the external noise as well as the cable
distortion appear in the grid circuit as voltage sources... maybe wrongly?
Here possible comes into play secondary vs primary cart loading:
with primary loading, the cable behind teh SUT passes virtually no current as the 1st grid impedance is huge, while with the secondary load
there is some current in the SUT-grid circuit as well. Which scenario is better, no idea as there are quite a few more factors being changed
(e.g. FR characteristic of the SUT may change with secondary loaded or not, etc).
Cart point of view is ineteresting, must give it a thought, but unless the cable has a huge capacitance why would it be difficult for the cart to drive?
There is also incomparably more cable in the SUT windings, which is usally an ordinary magnet wire....
Anyway, indeed I've never experimented with this particular cable (I've always though that separate SUT boxes + 2 more RCA plug crap + extra cable
in teh chain is a stupid idea and changing 5" chassis wire to 2" I leave to AA folks).

Cheers,
N-set
