My VPI MK3 skips if I walk near it.Should this be?

Paul's comment is on the money. I have had a VPI HW-19 Mk4 for many years, and my older home has rather "flexible" wooden floors. Like you, the tonearm on my VPI TT bounced whenever there were footfalls near its' location (it even bounced if our overweight cat jumped down from the couch to the floor). I tried a lot of different approaches to solving the problem, and none were totally effective.Then, about 2 months ago, I replaced the TT's spring suspension with the Sorbothane pucks from VPI, and I no longer have a problem with tonearm "bounce". (An added, unexpected "plus" is that bass frequencies seem tighter.)

The pucks (and the Scout / Scoutmaster cone feet) can be purchased from Elusive Disk. Here's the link:

Installation of the pucks requires some minor changes to the turntable. Rather than go into all the details here, please drop me a personal E-mail and I'll tell you what to do.

One other comment: if you decide to buy the Scout-type cone feet, note that it is less expensive to buy them separately from the pucks, rather than buying the upgrade package which includes both items.

Thanks for the advice I might give the sorbothane pucks a try.The table came with brass tiptoes that sit on top of flat brass inserts.Come to think about it tiptoes tend to
not absorb energy very well,but transmit it very effeciently.Sorbothane would probably work very well.

If you have a basement or crawlspace you can put floor jacks under your rack. Also you could try a Air Mass 19 from Bright Star Audio. I'm surprised to hear the pucks work better than the springs. I may have to give this a try...

I've heard VPI is going from springs back to pucks. I have a Mk 4. I removed the sorbathane feet and istalled brass spikes that threaded fine and were the same height as the SAMA. Much less motor vibration. Then I saw that Black Diamond Racing is making vibration kits for the Scout and Aries. The kits are 4 carbon fiber pucks and a 5" round platform for the Aries. So I bought the Aries set and it was like magic. I have one of the new SAMA's so it was a bit of a trick to get the motor on the platform. But the spikes go into indentations in the pucks and the motor on the platform. I can't recommend this enough. Music Direct sells it. They also sell a BDR record clamp that is out of this world. $300 though. Nice thing is you get a 30 day money back...
