Korf has their new arm on pre purchase.
I was leaning towards it, but a different came up secondhand… so more expensive (even used) but it is “end game” for me.
One preferred option (but not must-have) is universal voltage, as I may move the unit to Europe later.
I would not worry too much.
I have been running 110v equipment in Au for a couple of decades, and have always yearned to get rid of the transformer. And recently I did.
However a lot of people are running pricy power conditioners that among other things sometimes have isolation transformers. By running a 230v to 110v transformer my system seemed to be pretty immune to a lot of power supply issues.
I know that on the Sota they have an external supply… And maybe others do as well.
The legacy Luxman Micro-Seiki etc Japanese tables need a 100v… so they need yet a different transformer.
My current vintage turntable (Project Perspective) is 22 years old, and while I don’t know how to compare to something really amazing, I can say that my setup is lacking detail and bass. The tonearm is terrible to keep aligned.
Maybe it only needs an arm?
Are the rumble specs on it?
Perhaps an arm with more mass is needed, or maybe a high compliance cart would suit it?
The arm+cart is one beastly combo, but the table is generally separate and not part of the bass. Maybe some suspended tables affect the bass…??
Personally I would be optimising the arm before the table, but I am totally guessing at your table.
