Ralph, So sorry that I volunteered you for TP questions. That was unfair of me. (I think maybe that was why you wrote, "sheesh".)No, it wasn't, and no worries.
would like not to drill into the plinth though. The arm I got is from John I think you know him.@jtsnead , there's no need for that- if done correctly, its all reversible with no evidence it ever happened.
" Want to change the stock arm. ", what's wrong with. What do you do not like?
The gimball bearing on the Technics arms is really very good design and your GAE tonearm is made from magnesium that's similar on some of the top SME build material.
The stock arm is competitive with many high end arms.
But both the Triplanar and the some of the SMEs have something on the Technics arm, which is that the bearings are in the plane of the LP rather than the arm tube. This allows for more consistent tracking force in bass passages and negotiating warp. It makes a difference as to how well the arm can play bass. The Triplanar is far more adjustable, and has much harder bearings; VTA can be adjusted on the fly, and the arm tube is damped for less coloration. A removable headshell means that there are more mechanical connections, which can degrade the sound when dealing with very small signal levels. That is why the SMEs and the Triplanar do not have a removable headshell.
