Questions Regarding Installing a Wheaton Triplanar On A SOTA Cosmos

@neonknight ​​@atmasphere ​​@lewm , I have scoped it out,  The problem is the dropped counter weight. It runs into the back of the plinth. Yes it will fit. If you cut the back of the plinth away at the right rear corner behind the tonearm well. You would have to put the cartridge on stilts to get the arm up high enough and you would lose the right rear dustcover hinge. 

Lew, the record imparts the energy to the stylus which is suspended. Everything below the resonance frequency is passed to the tonearm, everything above the resonance frequency moves the stylus relative to the arm and the reactive forces must be dissipated by the record which also has a resonance frequency depending on the record's thickness and how firmly it is held down. At frequencies higher than the resonance frequency the record sings like the diaphragm in an old Victrola which is what you are hearing which is high treble. If the record is fixed and can not move across it's entire surface that energy is dissipated by the much heavier platter and you hear nothing. Larger, heavier, stylus/cantilever combination put more energy back into the record and the needle talk is louder.                                                                               

This is your model to explain what you believe a priori. That’s fine.

@neonknight VTF and antiskate not VTA and antiskate. My mistake. 

@pindac That's it! You are an oddball. Glad you figured that out:-) I was getting worried. 

@tomic601 The only person more arrogant than you is me:-)

The lyra has less needle talk because it has a very small stylus and boron cantilever. It puts less reactive energy into the record. It also has a very lightweight stylus mounting system. If you look at the pictures in the link above you can see it easily. The end of the cantilever is forked and the stylus sits in the interspace between the two prongs. My Sonic Lab uses the same supplier. The MC Diamond and the Soundsmith Hyperion, due to the nature of their cantilevers, have the stylus held on to the end of the cantilever with a big glob of cement.  

One of the reasons I like vacuum clamping and the Sota is the vacuum clamping effects on record resonance along with the engineering and construction of the Mat and platter. The other advantage is a flat record and pitch stability. 

@lewm It is not my model. It is my test. Freude schoner gotterfunken, Tochter aus Elysium, Wir betreten feurertruncken, Himmlischer dein Heiligtum:-)

I wondered IF you noticed that glob of cement….

I for one find @pindac a very interesting audiophile and music lover …. bravo
