you are going backwards with the parasound...the levinson is in another league.....maybe a 600 or 1000 watt McIntosh monoblock...maybe the autoformers will help with the low impedance and demands of your speakers...
a Bryston 6b or 7b is a 500 watt monoblock that can be wired to operate in parallel if that helps; these amps work well into low resistances and are moderately priced considering...about 2000 or a little more
