I'm amazed to hear that for 30 years Colin Macey and Derek Jenkins never set up my Sondek properly. With all the upgrades and new cartridges, that must have been an expensive bunch of incompetent setting up.
When Urika removed the stiff arm cable we were told that the crucial effect of arm cable dressing was no longer necessary because the Radikal was so good. You don't have to be an engineer to smell a rat there. After that my skepticism about Sondek-whispering kicked in hard.
Yet, my old mushroomed Lingo 1 Sondek was used at a CH Precision open day six months ago and I had reports that everybody was amazed by how good it sounded. While that set-up alp looks majestic in the distance, I'm happier in the foothills.
My current Sondek sounds great with Stack Alto, Karousel and mushrooms. I can set it up easily now. It has quite a good tone-arm too.
