I asked a similar question some time ago, with respect to a Linn. Here are edited (for brevity) responses from TWL and another 'gonner:
From TWL:
Cp,... I can tell you that the cable routing of the tonearm cable through the P-Clip in the base of the TT is paramount to the proper operation of the suspension of the Linn TT. If these requirements are not met, the TT will sound like poo-poo. The stock Linn cable is not the greatest cable on Earth, but it will at least let the TT be set up like it is supposed to be....Personally, I would leave it alone. If there is a problem with the sound of your TT, I would suspect set-up problems, or need for adjustment. Your audio dealer obviously knows nothing about a Linn, and you would be well advised to steer well clear of him on these matters. This is a job for someone that knows what he is doing.
From Sc53:
I had my Linn dealer replace the stock Linn tonearm/preamp cable for me with a Cardas balanced cable that Ayre sold for use with the phono stage of its K3 preamp. After a lot of struggle, he got that Cardas cable properly mounted and threaded through my LP-12. Unbelievably, I felt I liked the old cable better, and had him change it back! But if the dealer knows what he's doing, it can be done.
