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.
VPI Scoutmaster Upgrade
I presently have the following VPI Scoutmaster configuration:
VPI Scoutmaster
JMW-9 Sig. tonearm
Periphery Ring Clamp
Center Weight
SDS
Dynavector DV-20X Low MC
Dynavector P-75 MKII
I very please with this configuration but would like your opinion on an upgrade to my existing configuration to further improve the overall sound.
