Just added a Sunfire Cinema Grand 5 channel amp to my Denon 3805/3910, Monitor Audio Gold setup (new pics in the Members Systems Thread). Wow, what a difference. I Bi-wired the MA GR60 fronts using Sunfire recommended method of Current Source to the Mid/High and Voltage Source to the bass. Both two channel and 5 channel sound incredible. Now, I really feel like I'm getting my moneys worth. The sound so much fuller and more detailed and it will play LOUD!
I found the Sunfire on AudiogoN for a good price and sent it to Sunfire for a referb. Only cost $235 plus shipping to Sunfire. They pay return shipping. Very nice deal and the amp is working perfectly and driving all 5 speakers. Sorry to gloat, but I feel like a kid at Christmas
