Given that you would seem to be recreating what I found unsatisfactory, I'd highly recommend auditioning them with your amp before using the Aro with your PL.
For me, they were great with female vocals, acoustic blues, some jazz, but could not keep up with rock or other more "heavy" music losing detail and sounding very muddy.
