RS A1 Labs rewire

I once read a thread here whereby someone had done a rewire on their
RS A1 Labs stock tone arm resulting in an improved sound. I have had this arm
for several years and replaced the stock wire with same from the factory. I have tried but have never found a wire light enough to replace it with for an upgrade
in sound . I also understand that they went from cartridge leads straight to
the pre amp inputs. I would appreciate it if anyone can shed some light on this.

Thanks

Hi

Would something like this be suitable?

They have 41 gauge but I am wondering if it is flexable enough.
The wire on my Schroeder DPS may be suitable as it is very thin and flexable, laquer coated copper.

I just rewired mine yesterday with Discovery cable. I left the headshell leads as is, but I had broken the existing wire at the pivot, so needed a rewire. I was afraid this might foul the pivot, but have had no issues yet. And it's sounding pretty sweet as it burns in. Maybe not as much air as the original cable, but the midrange to mid-bass sounds more solid. Of course, this is with only 10-20 hours of use.

PartsConnexion has Discovery for around $15/ft. You could just extend it to the preamp input, I imagine. I chose to wire it to the RCA outs on the arm as I have a couple great phono cables.

Why don't you use Acrotec 99.99997% (6N) purity stress free copper wire from Nippon Mining, Japan. It is 46 gauge copper wire with polyester varnish insulation. Available from www.percyaudio.com under the category 'Chassis wire'.

This should be flexible enough. I have the same arm and have planned to get around to rewiring...however too many projects at present prevent me from doing so. Hope this helps. Let me know how it sounds if you use the Acrotec.

Thanks for all the input guys.
A few years ago I replaced the leads with the factory stock but I did some surgery to the arm as well. The gentleman at Sakura Systems suggested that
I may want to discard the junction box behind the cartridge leads and simply go direct from cartridge to RCA at the base. This resulted in an improvement in sound because of one less connection in the signal path. The only downside is
that I had to increase the tracking force. Also, I don't have as much leeway weight-wise as before. This is because the arm is effectively lighter now that the junction box has been removed. If I were to buy a new RS A1 arm I would do it again because of the gain in transparancy.
Now I am thinking that if I were to remove the RCA junction at the base, and
proceed with one long lead directly to the pre, I would gain some more transparancy.
Dickson that Acrotec wire sounds interesting, it seems thin enough.

Thanks again guys, and I do recommend the removal of the junction box behind the cartridge leads.

Cheers,

Hi Tessera--Did you end up doing this rewire? What wire did you use?
