I have a VPI that uses the Memorial 10.5 unipivot tonearm. Like many, I prefer the unipivot design, but I want to share two essential 'tweeks'.
A. When installed, the tonearm rests in a 'cup', and VPI recommends the adding a viscous oil to this cup to dampen unwanted tonearm vibration (I got mine from VPI). It really works - Simple, effective and no 'snake oil' needed ;-)
B. Purchase and use the 'Anti-Intuitive' counterweight accessory from Soundsmith. Again, simple, effective and it makes tonearm set up a 1000x easier.
Good luck and enjoy your TT.
