What is there to gain

my setup,same as yours, must have came with an aftermarket heavy weight. mounting a benz gold, had to add a strip of lead to weight the head, as the weight was as far forward as would go.
would suggest the mark III plater/bearing for a big jump in sound.
if you go with the hvywt i'd be interested in your stock PT-6 weight. kurt

Scott, let's put it this way, OH MY GOD!!!!!!!

EVERY aspect of your tonearm will improve. Tonal quality, compliance, everything....... will improve.

I just installed the Expressimo end stub and the Heavyweight counterweight on my VPI MkIV/Rega RB900. The difference was absolutely PROFOUND. I'm not talking about subtle differences, they are immediately apparent from the first 30 seconds of playback.

Scott, don't even hesitate on this one. You will be Soooo satisfied with the results. Worth every penny you will spend and then some.

I am positive you will receive other praise from other users in this thread.

Happy Listening, Ed.

Scott,

One of the benefits is that you would continue to feed your habit. Nothing like the path of least resistance.
