Hey Canuck,
I am a fellow owner of a Marantz AVP 550, and just replaced it with the Outlaw 950. I still use the Marantz in my living room mostly for music now, it still sounds great.I upgraded to the 950 and couldn't be happier. I wanted component switching, DTS, PLII. I use Boston Acoustics all around, VRM-50's upfront, VR-12 center, VRS pros for surrounds and Micro 90x for back surrounds. I know how good the Marantz sounds so I was pleasently surprised when the 950 surpassed it. Enjoy!!
