Toby runs them and his boat stereo is a top of the heap system....he also runs focals....Focal's and Audison it is tough to do any better...
(we sell both ) IMO
Would say it has alot more to do with the Focal speakers never been to impressed with the Audison amps, Would put the PDX up with itall day long.
In fact we put a PDX in our Focal display and the Audison is on clearence.
