Tonearm mount to the plinth vs arm board vs rotating arm board vs isolated tower

Dear ct, with your ''cheap TT's argument'' you are actually strengthening my  which was ''don't mess with TT's''. This
than should be ''don't mess with cheap TT's''. 

@nandric 
Nikola.
I never used the words "cheap TT's". You did, and it changes the meaning.

To the idler fan (the subject of this thread is about an idler); there is "hidden" "intrinsic" value in what is acquired for this small sum of money .....if.

that person has the means to transport the "mechanical's", into another "body" (plinth).

Idlers bring unique challenges to Audiophile projects.

Dear ct, one can express the same thought with different words.
So persistence  on ''exactly  used words'' will not do ; meaning 
can't be nailed to specific words. Otherwise our memory would be
the same as by computers. 
Also the valuation of expression ''cheap'' may differ among
nations. The English saying is: ''I am not rich to bay cheap stuff''. 
My own is the usual understanding of this word. I as you deed
not emigrated from former Yugoslavia to the West for ''cheap
things''. On the contrary (grin). Check my carts collection!

For the record, Nikola, I have never replaced or modified the platter on my Lenco. Along with the motor and idler wheel, the platter is OEM. I am in fact skeptical of those who have doubled up on the platter, using two original platters, one on top of the other. And I am not even aware of anyone who makes a candidate aftermarket platter for a Lenco idler. And finally, I don’t approve of doing any of those things, because I think the drive system was designed and conceived to drive the platter as is. Altering the mass might not be a very good idea. So, perhaps at sometime in the past, which I don’t remember at all, we may have had a disagreement having something to do with a Lenco, but it could not have been regarding my desire to replace or alter the platter. Without consulting anyone here ever, I did do one thing: I had the platter professionally painted in a vibration reducing paint. And then I placed 4 large O-rings around the circumference to dampen the purported tendency of the platter to ring. I got that idea from Win Tinnon, the guy who makes the Saskia.

Dear Lew, You made me again speechless. Heavy paint?
