FWIW, should probably let you know, for much less than the cost of an arm you could tweak more performance out of your existing arm than you would believe. Maybe even more than any of the arm upgrades being considered.
First thing I would do is order some fo.Q tape and TC. This special tape has piezoelectric properties that transfer vibrational energy into heat. This lowers the noise floor dramatically revealing incredible inner detail and micro dynamics that really opens the sound up with a sensation of incredible presence.
I put one strip the length of the arm tube, on the underside where I don’t have to look at it. Very hard to see. Then I put more all around and under the base and counterweight area, again basically anywhere out of sight. But when you hear how good it works you might not care! It can also go on or near the motor, plinth, under the footers, anywhere you think it might be good to control vibration.
Its a super high quality tape with a beautiful adhesive that somehow manages to stick incredibly well yet be easily removed without leaving any residue. Just fabulous stuff. If you can’t use it all on the arm and table the rest can be used on speaker frames or the phono stage, just try it and see. For $40 by the time you use both sheets you will feel like you have a whole new arm.
Then coat all the fo.Q tape with TC. This will take the tape to a whole new level of refinement and extension. By the time you have done all this the improvement will be about as much, if not more, than when I went from a Graham 2.2 to OL Conqueror. In other words you get $3k of improvement for $350.
Next after that would be Synergisitic PHT. Green Dream and Black Widow. You can use both. Others who have followed my recommendation on this are really happy. Also ECT, which work great on the tone arm base. You can see all these being used on my table here.
