SME 30/2 Controller

PG was there are noticeable difference between the 2 controllers? Is so what did the new controller add? 

I certainly remember hearing a slight lowering of the noise floor, giving the music just a little more presence. But it was some years ago, and I would not wish to make too strong a claim. In any case I remember it as being slight but worthwhile. I certainly did not think, 'I will pack this up and send it back'. 

With the new controller it is somewhat easier to adjust the speed (on the older one it was necessary to insert a special screwdriver). 

The tower gaps as set with the tool provided simply set the upper platform level with an optimal “stretch” on the elastomers of the system. All the fluid in the pots do is help damp any bounce that might occur. This is unlikely as the unit should be placed on a fairly substantial platform. The towers are not “shocks” where the internals are charged to provide rebound etc. the shock absorption comes from the elastomers. Overall, the height of the towers do not matter in the overall use of the table. However, they should not be able to bottom out the elastomers, nor should they be set so the elastomers don’t have much tension. Otherwise, they cannot do their job properly. Be sure to set the height with the table fully assembled platter installed and arm of choice installed to assure proper level on the upper plinth.

Regarding the damping of the V tonearm, that is entirely different and has nothing to do with the isolation of the platform. Some don’t run damping fluid in the tonearm reservoir at all, I’ve tried it both ways and prefer to damp the tonearm. It seems to give the arm more presence and body. YMMV.

The tower heights are set without the record clamp on, yes?  The manual implies this I think, but I did always wonder.

I don't have any damping fluid for my V, but had some on an earlier IV. I am intrigued to find that you say it improves the V. Most online comments suggest it isn't worth the hassle/expense. I imagine it depends on cartridge compliance (says he without quite understanding what that means).

The V damping fluid is a fairly viscus silicone gel stuff (for lack of a better description). It’s really not a big deal to use/install. I had a syringe of it anyway, so it wasn’t any additional cost for me. The only time it can be a pain is if you spill any, or maybe spill when moving the table/arm. It’s a b1tch to clean up for sure. In terms of preference overall to each their own. It certainly isn’t “required”.

Regarding the clamp on or off the table, I don’t really think it’s a big deal either way. The clamp is fairly heavy and it might change the level a bit but enough to make it an issue? Doubt it. When I set up mine I’m pretty sure the clamp was on, but I honestly don’t remember. I’m not sure where the manual mentioned anything about the clamp relative to the tower adjustment. I might have simply shined it at the time.
