RIAA, Questions only please
Agreed.  However, Roger seems more interested in conducting semantic arguments than in educating anyone.  I was reading a thread in the tech forum about RMS power and it was fairly civil until Roger jumped in and it became almost comical in how pe... 
VPI 40th Anniversary Table After Warranty Support Question
While it may be a thought experiment (since very few people have seen an actual HW40 outside of a trade show or the roll-out at the VPI house), I think the OP raises some legitimate concerns.  The concerns could certainly be addressed, but from wh... 
Pheonix Engineering Road Runner

Thumbs up for ultrasonic record cleaning
@fleschler- You have it backwards. A higher frequency US will have lower energy release and it will be much more evenly distributed than lower frequency. The cavitation bubble size is inversely proportional to the frequency; the higher the fr... 
Thumbs up for ultrasonic record cleaning
@whart - Thanks for your thoughtful response. The general consensus seems to be that US RCMs do not cause any damage; I suspect that if any microscopic changes (damage) are occurring, it is subtle, random, isolated and cumulative, possibly evading...

Need help and advice on a VPI 3D arm
HW-Thanks for weighing in and clarifying the situation. I’m a Prime owner (w/3D arm) and have a few questions:Quote: "We now have 3200 3D arms made and shipped with a twisting rate of roughly 1% (almost all in the first year)".This would seem to i...
