You didn't mention a budget. For $2K and under, Rega makes the best arms for the dollar. It's not even close. RB3000 ($2200), RB880 ($1200), even the BR330 at $600 will outperform ones that are several times the cost. They also have a super expensive one made out of titanium not available for a standalone purchase that comes with their super rare/expensive Naiad that was used as the basis for their high end tables.
Above that, I leave it to the big spenders who patrol AG. I know there is an interesting one for $4K that doesn't touch the plinth from Integrity HiFi in Canada. Only found out about it because I bought a Tru Lift arm lifter from them. They swear it makes any cartridge sound great. Conceptually it makes great sense to have total arm isolation with no motor or platter noise or vibration. Anyone ever try an arm totally separate from the table?
