I ordered the A52 yesterday at work around one oclock in the afternoon. Fed Ex delivered it to my house this afternoon. That's the benefit of living so close to Audid Advisor here in Michigan. But the bummer is I had to pay sales tax. LOL On a more serious note I just have to say that I am literally amazed at the power and finesse of this amplifier. I had coveted one of these forever. I had previously a Marantx MM9000 5x150 watt amp in my system. The Marantz amp was certainly no slouch, especially with home theater. But this Parasound has so much detail and authority. I am not gonna sleep for the rest of the weekend. Concert Blu Rays and movie marathon. LOL I would challenge anyone that has not heard one of these to at least take it for a test drive. I am so glad I didn't waste money on the higher powered A51. 125 watts of Parasound is more than enough for my living room.
