Mark Levinson 431

Interested in your opinions hearing opinions of The Mark Levinson 431 vs Aragon 8008ST with respect to how it may perform in my system. I have an old 8008st but it is our for repair and Im suffering withdrawal now that Im relegated to an Onkyo 85 wpc ht receiver....yuck. I can pick up a 431 locally.
My system consists of a VTL 2.5 preamp, Nad C542 Cd player, Paradigm Studio Ref 100 V3 speakers, Paradigm Servo 15 sub.
