Especially if you're as old as I am.

Back when the HW-19 II was new, we all twisted the belt into a figure 8. See if it doesn't tighten up the bass which will clean the mids. And maybe have a positive effect on those older motors and pulleys wandering.

Unless your belt is extremely stretched, why do it. and If it is, there is the cause of your problem.

I've got a HW-19jr. that's currently undergoing a mini-restoration...I'm wondering if mass-loading the plinth will improve anything...

I added 2-3 lbs of Plast-i-Clay to the top acrylic of my Mark III...there was some benefit in doing so.

I didn't remove the springs, I left 'em there....but I filled the innards with wads of Acousta-stuf (usually used inside speakers) to damp the steel ringing.  I though it, too, was slightly beneficial.

Using Tufoil in the bearing was also worthwhile.

The effects of all three were important, but pretty mild.  I still like my direct drive better.

But, that could change if I ever added SAMA and SDS....but at a cost of $14000.00 more for that I'll stay blissfully ignorant and a bit richer  :wink:  That's just my view - to each is clearly your own  :thumb:

The SAMA and the SDS make a big difference.  I have a Denon DP-75 Direct Drive also, and it is damn good.....as good in the bass as my VPI-19 Mk.IV and my SOTA Sapphire, but it is pickier about the shelf its on.  It has to be on concrete.

I'm a big believer in suspended tables.  These unsuspended tables today are great if you set them on a rigid concrete column, but are susceptible to structural vibration on ANYTHING else.  Any turntable mfg. who tells you otherwise is full of BS.  They all collectively went to un-suspended tables to go cheaper, and because the suspensions themselves COULD impact the sound.  In other words the transferred the structural vibration problem to the users. 

This is a huge cop-out, but audio companies get away with cop-outs everyday.  Some of the stupidest audio designs in history are the mega-buck crap that appears in TAS and Stereophile on a monthly basis.  The audio industry seems to have set itself up to sell "sizzle" and not real audio improvement.  I still do not understand why they haven't move onto 5.1 multi-channel (MCH) as the standard when it is clearly superior with a MCH recording (Pentatone for example).  Oh well.
