The problem is Biff, lots off well meaning people see a potential to supply/offer an improvement/upgrade for a particular product or application, without fully understanding the engineering physics applicable to the intended improvement.
My Bearing is I believe the best designed and engineered bearing that it is ever possible to produce within the constraints of the volumetric envelope that is available within the SL1200 motor mechanism. In other words I just cannot make it any larger!
I have received numerous emails from people enquiring if I can design and manufacture a less costly bearing. Yes I can, but it would be no more than what other people are already offering. I set out to design the best bearing possible for my own application, it was more by accident than commercial intent, that my bearing was taken up by the SL1200 audio fraternity as being the only one to have if one is serious about really improving the sonics of the SL1200.
For my part I am comfortable with people buying the less costly options and being convinced (and telling everyone who will listen) that they produce the best sonics possible, after all not everyone can have the best.
What people do not understand is that the very flimsy die-cast alloy housing is about the weakest part of the bearing structurally speaking. And yet others offer some sort of a super duper insert into this housing, which in one instance that I am aware of would actually reduce the rigidity of the whole assembly. The mind boggles.
