Which Tonearm to go for VPI HW-19 III?

Steve, Sdcampbell hit that one right on the head. The MkIV upgrade is VERY significant. I also use the RB900 arm. If you can afford the MkIV upgrade, do it. Your stock RB300 arm may fall slightly short after the upgrade.

Although, your 300 arm can be upgraded quite nicely. See below:

The RB900 arm is a very nice arm. But, it is even better with some of the mods such as VTA adjuster, Heavyweight counterweight and internal wiring. All those same mods can be performed to your 300 arm (which you already own). If you ever decide to upgrade to the 900 arm, you could carry over the mod. parts from the 300.

Best of luck, Ed.

Steve, many of the dealers of cartridges and turntables, (Elusive Disc, Acoustic Sounds, Audio Advisor, Etc,) will carry the MkIV upgrade. It can also be ordered from VPI directly. I can tell you that VPI is really backed up and presently the Aries Black Night platters are in very short supply, if at all. You would probably be looking at about 3-4 weeks for delivery.

I believe that the MkIV upgrade (platter, bearing and suspension) is about $600.00+, the drilled Super armboard (1" thick) about $100.00+.

The RB900 arm is factory supplied with a better quality tonearm cable than the factory 300 arm. I don't know any details on that specific wire. There are many different manufacturers of Rega upgrade cables. I can tell you that my upgrade cable is by Incognito, and the actual wire is Cardas Litz. ANY good quality upgrade cable will work wonders for your RB300.

A fully modified, rewired RB300 is sonically, a completely different tonearm than the factory RB300 tonearm. Quite frankly, it is within spitting distance of the RB900 arm and then some. But, that's comparing to a fully modified RB300 including rewire, weight, endstub, VTA adjuster, and maybe even the TWL mod.

My opinion? Go for the MkIV upgrade first. It will put that turntable in a whole nother' league. And you can sell the existing MkIII platter and bearing here on Audiogon to offset the cost of the upgrade.
