Help Please With A Replacement For Old Aragon Amp.

There aren't any dealers allowing home auditions right now in my area so would appreciate some input n the following.
I think its time to upgrade from my old Aragon 8008BB power amp. It's been good to me but I've got the upgrade bug. Any suggestions as to a worthy replacement? I'm thinking no more than $1500-2000.  I've considered a Cambridge Audio Azur 841W or Musical Fidelity A3 cr power amp. Not opposed to going integrated.  Speakers are ATC Scm 19 V2
85db sensitivity but an ATC dealer told me they don't need gobs of power as often thought.  Pre amp right now is a First Sound Presence MK I (tubes)  The Aragon doesn't seem to grip the speakers despite it's power rating.  Thnks for any replies.
