I do not have the experience that most are stating here.
I have and AR-XA with the stock arm and an AT-440Mla. I rewired the arm with Litz wire and dampened the top plate. I also added a SS thrust plate and polished the spindle bearing.
I also have a TD-160b MK II with an Linn Basik LVX arm and a Grado Sonata 1.5mV.
In my opinion the AR-XA equals the TD-160b (but I'm not done modding the TD-160)
