I apologize for my tardy response to your inquiry about the Marantz MM9000.
So far, I have been satisfied with the performance. Not that my SR9300 lacked sufficient power, cause it doesn't, but I wanted to see if an external amp would improve the performance of my speakers. Klipsch Reference speakers are arguably the most efficient speakers out there and it really doesn't take a lot to drive them. But more power doesn't hurt either. I can say that I do hear a big difference in the rear surround sound stage. I have a 6.1 configuration and I really thought I was missing out on a lot due to the fact that I only have 1 rear speaker. Well, now, it's a completely different experience. The surround channels are more pronounced. When I listen to multi-channel audio (SACD/DVD-A), the sound is more focused and forward, stronger if you will. An example, in the AVR speaker level settings, I had the dB level at +6 for the surrounds and +5 for the rear back. Now that I have the MM9000, the dB levels of the surrounds are at 0 and the rear is set at 0.
I literally had to turn them down. I did in fact calibrate the old fashion way, with my Radio Shack SPL meter.
As far as the fronts and center are concerned. The RC35 center channel has been criticized by several owners, describing the performance as underwhelming; at times, undecipherable; and in some instances depending on the soundtrack, muted, etc... I didn't understand until I added the MM9000.
Compared to before, the RC35 Center channel is now the most prominent speaker of the array. The voices are clear and I can decipher every word. I guess power does clean things up a little! Or a lot in my case.
As for the Fronts. There is an improvement, but not an overwhelming improvement. The SR9300 when driving 2 channels is rated at 165 watts per channel. The MM9000 is rated at 170 watts when driving just 2 channels. My RF35's do sound a little stronger in the low end and the imaging is slightly better and the sound stage hasn't changed. It was always decent.
So moral of the story, there has been an overall improvement with the MM9000. I paid $479.00 on eBay.
I believe it's a good value. Whether or not you'll have improvement over your current set of amps is hard to say. I went from AVR amps to a dedicated multi-channel amp. You are considering switching out dual 2 channel amps for a multi-channel amp. A good one mind you, but it is a multi channel type. At the least, you will have a marked improvement in the surround sound performance. It's just something to consider.
I hope this helps.http://us.marantz.com/c_mm9000.pdf
