New cables for Thorens TD 160

Hi All,

First post, long time fan. Anyone replaced the
RCA leads for a Thorens TD 160?

I picked up a Thorens TD 160 recently. Literally-
someone was carrying it out to throw away. It had a
Grado XF 1 cartridge and broken RCA jacks. Okay, I had
the needle scoped and it still had 1/3 of its life left,
but I got a replacement anyway. Had a local shop replace
the leads with shielded cables they swore by. So I hooked
it up. The thing put out maybe half the volume of my CD
player. I had to turn it up very high to get decent gain,
and the midrange was pretty sad.

I replaced the Grado with a Pickering XSV 3000 I happened
to have around (!) and got pretty much the same thing
(with more detail and soundstage of course). Not good.

I am thinking the cable replacement is the culprit. The TT
is clean and works in all other respects. Does anyone have
a recommended cable for this purpose? I appear to need one
with low capacitance. TIA!
