Tonearms are a very attractive item to be used in a System, there is an allure about the device, to the point a LP Replay enthusiast can lose many hours observing the models available.
The Designs and Aesthetics commonly discovered can easily be described as quite a feat of engineering.
The Devise has to offer an extremely precise accuracy in its function and maintain the designed function, when met with many different environments, any changes to properties of materials used within the design, as a result of an environment, has the capability to impact on the performance in a detrimental manner.
Learning about a Tonearms Design Intent and how its consistency in unadulterated function has been the basis for the choosing engineering methods and material selection will be quite a valuable undertaking.
A very nice aesthetic, one that really shouts pride of ownership, is not a compensation for a design that is supplied with deficiencies in place where the engineering and used materials are not optimised.
What really matters, is what is under the hood, what designs and materials are being used at the concealed locations, it is quality of thought and work undertaken for the out of sight various interfaces that enables the the magic to happen.
