I purchased my square motor, smaller plater spindle, classic with a bent tonearm and in poor shape overall. The guy who refitted the new carbon arm wired the tonearm with a coated silver wire that extends all the way to the preamp. I guess this qualifies as a tweak?
The sensibility of the Well Tempered design is its greatest virtue. Getting one of these setup correctly can be a little tricky but doable. Having someone with setup experience install your cartridge and make the necessary coarse adjustments would be my only suggestion.
