There is a good opportunity with the information being made available to discuss with Glen Oak Labs what procedures they carried out as part of the TT's service.
As it has a Warranty on their records it should be easy for them to dig out the Invoice and see how there charge was itemised.
Tonearms have their own sonic character and can be a make or break choice.
You are in a very good position to absorb information and assess choices made by other users of the TT.
SME 3009's are a great match for a MM, well that is how I used mine during the 90's, with MM's when I had it mounted on a Garrard 401.
SME IV Models have great marketing, they can get under ones defenses and can become a obsession to be acquired.
The SME IV from my recollections found favour in being used with Idler Drives, as the Tonearm is capable of taming the Overwhelming Bass that can be produced with a Idler Drive.
This is a valuable trait for a Idler Drive, it is not so welcome on other drives.
Careful selection is a consideration for the coupling/matching of a TT>IV.
I still own the SME IV model used on my Garrard 401 with a MC Cartridge, but it is not in use.
I have used a Audiomods Series Five with a MC on another Idler Drive which is a PTP Solid 9 TT.
I have not compared both the IV and the Series Five but there are similarities.
The IV has also been loaned within my HiFi Group, it was on a SP10R and compared to a Origin Live Tonearm and a Glanz Tonearm.
The Glanz was the preferred Tonearm by the SP10R Owner.
I am at present using a Redesigned and Rebuilt Audio Technica AT-1010, on my Direct Drive Turntables with a Rebuilt Moving Coil Cartridge.
It is not only I who has been thoroughly impressed with this Tonearm Design.
Other owners have exchanged their Revered Tonearm Models,
relegating them to the Sub's Bench and the PMAT 1010 has taken their place.
The PMAT 1010 as it is known, is the best Tonearm I have used to date,
my search is finally over in this area of HiFi.
Even though one more breakthrough has been identified for the already impressive design, and is soon to be made available.
As said the selection of a Tonearm can be a make or break choice,
the interaction of the Tonearm with the environment iit is to be used in, is also critical, when the choice is right, it will be a very strong marriage.
Hence a earlier in the thread suggestion to look into the Isolation of the TT.
