Stock Rega arm-wiring -- how Cheesey???


Guys,

I'm setting up a BIX turntable with a stock Rega RB250 and I bought an upgrade stainless steel counterweight and arm stub. I'm concerned that the stock arm cable appears cheesey, cheap, cheap, cheap. I see a lot of folks upgrading the wiring. My question is: just how terrible is the stock wire? Is it at least listenable?

I also have a Profile II arm, which I was thinking of mounting instead, but I'm concerned that the armboard hole might be in the wrong location (for proper geometry) because the pivot-to-stylus distance is 10mm shorter on the Profile arm.

Any comments or suggestions? If someone has used the stock Rega arm wire and then switched to something better, I'd be interested in hearing your impressions of how the sound improved.

Thanks!

According to Origin Live - replacing the stock wires makes about a 12% increase in performance.

Now... how they determined that it was 12%, I have no idea...
Plato,

Have you determined how accurate the speed of the BIX is via strobe or stopwatch? Wow or flutter? Sustained piano notes are often a good test on this latter question. And lastly, did your BIX come with two addition armboards even though you had the Rega mounted? Thanks in advance for your answers.
I have an P-25. The interconnects were very good, the internal arm wiring is only ok, but not the best. I needed to rewire for balanced operation so I got the whole thing done. The difference was dramatic. I was using a Grado Sonata, but upgraded to a MicroBenz Ebony and it REALLY came alive.
