Monday morning decision, and hopefully the final one. Talked with techs at Parasound, and they arrived at the same decision after hearing the results of my 2.5 days of playing with the A 51 & A 21. Seems the best solution is to replace the A 51 with three of the A 21's. Several memebrs here had the same thought that Parasound techs, and that is the A 23 will most likley have a problem powering the Axioms.

So now waiting a call back from my dealer as she is contacting Parasound to see if they can get the cost of the fourth A 21 down to what I'm willing to pay.
