Rega Arm mods-is it really woth t it?


Hello All,
I just picked up a Rega RB 300 for my AR ES-1 turntable. It is a real improvement over the stock AR/Jelco that was originally fitted; with dead silent backgrounds and most important to me, abolutely no grounding hum issues.
I am afraid of rewiring it for that reason-am I justified in being chicken?
Also, what is the ranking of the aftermarket
counterweights for this Arm? So many choices!
128x128wahwah
I was not saying the Audiomods is a RB-300. I had a Basis modified Rega and was considering an Audiomods at one time because it would be a drop in replacement. Much easier than getting a new armboard made and drilled.
Ok, I guess I should give it more time as I have only had the thing for two weeks. I will try out a different counterweight and start looking at a cartridge upgrade.
Somebody say Grace?

I think there should be a law that someone has to actually listen to a component for one year before screwing around with it. I think it would help a lot of people.
LOL! Chayro, there is so much written about mods for Rega tonearms that it almost seems as if this is an absolute requirement for these arms; hence my initial inquiry about doing this.
I dissagree about waiting a year to get grip of the sonic signature of a component or a system-If one has a known baseline to start with, 2 or 3 months should suffice for the experienced audiophile.
