As others pointed out, you haven't fully exploited the Rega's capabilities. Both the wiring and counterweight upgrades make noticeable improvements to an RB-300 arm. I kept my modified Rega arm and used it on a Thorens TD-850, with good results. Since there are 4 or 5 elements to this -arm, table, phono pre, cartridge, sometimes phono cable - you may be better off picking one weak point to upgrade, like the phono stage. That way you will be able to identify the source of any change in sound. You might as well take your time, since as you know, from reading this forum, it will never end.
