@dogberry I have shared with you in the past on occasions about your methods used for mounting Tonearms.
Additionally, I don't remember your Brand of preferred TT being discussed, but I am very familiar with SME as a Brand. I have heard the 3009 Tonearms in use for most of my time around Audio Equipment, a friend loves to get under the hood and extract every last morsel that a 3009 can offer, I have heard these in use on numerous occasions.
The SME IV and V model TA's have been extensively demo'd and as a result I have owned the IV Model for numerous years. It took a very long time until I discovered a TA design that superseded the IV and other owned TA's.
I have been demo'd the TOTR SME TT's on regular occasions in my days of visiting Commercial Events, it was at this time I chose to adopt a different drive TT.
Over the years I have encountered these TT's in use and not too long ago I was regularly receiving demo's of the SME 20/12 model in a system I was familiar with.
As for your own investment of approx' CDN- $54K, this is another outlay from a 'dye in the wool' Vinyl LP enthusiast, that is very close to the figures I have put forward.
Using my own experiences, which are made known and now using the contributions from forum members offered to this thread, there is a furthering of reinforcement to my own notion, that suggests there are constrained attitudes expressed by individuals for their purchases. It is interesting how there is a description of offer that mirrors my own, which is not wanting to aspire to something quite different than what is already created.
When seeing the selections made by 'dye in the wool' enthusiasts for Vinyl Replay Source Items, even though choices being made are not typical across the individuals in their Brand Selection. The accumulating monies outlaid are seen to be similar in requirement, to acquire the ancillaries that offer the individual a experience of replayed music that is meeting their unique preference.
