Got home last night, gave the wife and daughter big hugs and then vanished into The Green Room.
Opened the 3 boxes, unloaded the popcorn, unwrapped them from the bubble rap and to my amazement, they were in beautiful condition. Very clean, undamaged, nearly brand new looking less a few minor surface scratches on the top, all face plates are perfect looking.
Next, tore up the flexy rack to make space. Put'em in, wired'em up and then put in AVIA for a quick calibration. Everything is working perfectly. I ran a single interconnect from the pre-outs on the Marantz into a 'Y' splitter. From there, to the L and R inputs on the Adcoms. I used the right and left channels to bi-amp my RT55s and CS400.
Next up, Black Hawk Down. I know exactly what this sounded like with my Marantz as I watched it the night before.
Let me say, I have never, never experienced sound like this. The front soundstage just exploded. So clear and wide with such deep mid-bass. It was as if I removed towels that were wrapped around the speakers. Everything was so alive (for a lack of better words). These Adcoms just brought the movie experience to life. It really is hard to put into words. I did not break out the SPL meter during the movie, but on the Marantz dial, I am usually around 65-70. Last night I was at 80 and the sound was awesome, not fatiguing at all. The most I've had the Marantz to was 75 and after about 5 minutes the sound started to get fatiguing.
Currently I am using 10+ year old cheap Monster interconnects. I should get my new interconnects from Frank in a week, the check is going out today. I know this will bring even more improvement.
Thanks to all who talked me into these and answered all my questions. I had no idea it would sound so much better, simply awesome. I need another amp for my surrounds and then a pre-amp processor. Ohhhhhhh, I'm hooked.
Didn't have time to test much more as it was nearly 10:30 and I was tired. Tonight though, weeeeeeeee.
