Whatever arm you choose, strongly suggest that you modify the acrylic mounting board so that the new arm can be mounted directly on that. This will ensure proper coupling and energy transfer. Suggest that you may want to contact Detlof who has significant experience with the reference.
goldmund reference . which would be the best arm
i have had a goldmund reference for many years with the t 3f arm , as an experiment i decided to mount a 15 year old linn ittock arm with a cut down linn arm board, the results are very favourable proving the ittock is superior to the t3f linear tracker. Can any one advise a more suitable arm for this table as the ittock is hardly the last word in tonearms.
