I have have a couple of questions regarding cabling and connections. At
the risk of getting some daft and conflicting answers, here goes...

First, I've bought an old Technics SL-1800 off eBay, which I'm very
happy with, but I was wondering if it's desirable/possible to upgrade
the interconnect cable. This is a hard wired cable on this, as seems to
be the way with turntables, but the one on there is very old, and
looking a bit tired.

I shall be using a nice thick interconnect between the Phono amp and the
main amp (only has Aux input), and of course with gold plated
connectors. But this almost seems a waste if the turntable connectors
are old and tarnished.

Second, I've got a pair of Castle Severns, and also some reasonable
cable (6mm for the bass, and 4mm for the treble), and got some gold
plated banana plugs for the connections to the speakers (the amp in
screw clamp only). The banana plugs are the screw type, but is it worth
bothering to solder them on as well?

Cheers.
