VPI Scoutmaster Upgrade

I might consider the super platter as the next step. Not cheap but it will make a diference in what they refer to as PRAT. After that, go for the rim drive if you want to try something else.(will be available for scout master soon I believe) The 10.5i arm is nice as well but the 9 sig does a great job also. Just my 2 cents. I think you'll enjoy any of these in any order.

Having owned the Dynavector P75 MKII, and currently use a Dyna XX2MKII cart with Sig. Scout, I recommend a phono stage upgrade. I went from the P75 to a modded Simaudio LP 5.3, and I'm sure it would be money well spent. For about the same money, The JLTi, Swiss made, is tremendous as well, Audio Revelation has an in-home demo program. That's my 2cents.

I think I'd go with Sonofjim's advice. The 10.5 upgrade is not as urgent as the heavy platter and rim drive...both major improvements.

Do you actually use the Periphery Ring Clamp? I have heard a VPI HRX with and with the Periphery Ring Clamp. I prefered without. I was at a dealer, he was using watt/puppies and ML amps. They will sell the Periphery Ring Clamp if people ask for it but, and I tend to agree with them it is no good.

Mordante...en contrar.. Sure you can play your records however you like, but the combination of the clamp and the center spindle weight act to flatten the record against the table. ..if nothing else, that now flattened record enables your arm to glide easily across the record without the trip being an obstacle course with undulations which encourages sports "sports car handling" for your cartridge. Yes I know your cartridge tracks well, however, an easy trip makes for better sound. I am also wondering if your dealer had the heavy platter installed. I encourage you to listen to that platter for final judgement.
