If you read my reviews of the Pass Labs X-350.5 and the XA-100's it will give you details about why I found the X.5 series and XA series so musical and pleasing. When I auditioned the Parasound JC-1's I thought they were quite good, but not in the same league sonicly as the Pass amps. The sound of the X-250.5 should be about the same as the X-350.5, therefore it would sound great with your M-L's and drive them easily.
