The P9 may come across as a souped up P3 concept, but it IS a great and highly valid top end turntable, even if it doesn't float Techie owner's boats. That expensive ceramic platter wasn't done for show you know...

I just looked at the link to the origianl thread - WHERE do direct dives vibrate? The thing is, they don't! There may be an issue with the rapid servo regulator supply frequency/jitter? in the techie? but all these tweaks probably get rid of it at a stroke, and the Funk platter has answered any questions of the heavy platter changing things in the way the motor works.

Dynamic wow on belt driven decks is a HUGE issue for some. My way of dealing with it is to recommend a low tracking weight cartridge if possible, so the drive isn't loaded up too much. I know this doesn't solve the problem, but it certainly helps.

Too many blinkered idiots in audiophoolery, and if it takes one to know one, then so be it Never say never in anything - leaves you a get-out clause......
