preamp isolation

I have Symposium Rollerblocks with tungsten balls under my preamp. Yet, many of the thicker and stiffer IC's appear to be holding the component captive. I've added supports to my rack to help 'unweight' the pulling effect from the cables but I'm not sure how effective they are. Do the Rollerblocks still work properly with the cable resistance? Is there a better way? Thanks in advance.

I too have had issues with bearing isolation and cables pulling on the component. I have gone as far as building a cheap wood brace to support the cable so it puts no pressure on the bearing. No matter how you choose to deal with it, it needs attention.

John, I'm not familiar with transformer coupling. Can you recommend a site where I can learn more?

Check out the K&K Audio forum over on the Asylum. Also, read Lynn Olson's articles in VTV magazine and check out his web site: www.nutshellhifi.com/ The Jensen transformer site has some good info to: http://www.jensen-transformers.com/apps_wp.html

Could you put some brass heavy things on top of your preamp to help hold it down,i think Mapleshade sells some,i use a brass gear that i came off a press at work,not pretty but it works
