I used to have Marantz 7300 receiver with Bose Lifestyle speakers in my home theater. Everything used to work pretty good, including my xbox, ps2, dvd etc etc..

Last week, I just got new puppies, a pair of B&W Nautilus 804 and HTM-2 speakers. I have no problem using them for TV, XBOX and PS2. But, I am having problems watching movies or music videos on my DVD player.

As soon as I run any DVD, everything works great for 5-6 minutes, but then my receiver Marants 7300 starts flashing message "PROTECT" .. and then speakers stop.

Any idea what's wrong here ? I have tried to drive speakers keeping "Small" or "Large" options and between frequencies 80 and 100 Htz.

Any help will be highly appreciated.

Thanks

RS

First off, those speakers are out of the league of this receiver. I'd call it a mismatch for sure. I'm a big fan of Marantz, but these speakers will likely need a bit more power to adequately drive them. I would recommend either external amplification for the front two or three speakers or look at a receiver that can sustain more output.

John, thanks for your reply. I was thinking on similar lines that my receiver is unable to drive these speakers. I would appreciate if you can suggest some good receiver for these speakers


Thanks

If you already have your receiver and power is the issue, why don't you consider a power amp capable of bringing out the best in your speakers?

That would be my suggestion also, and this is what I did with my 8300 - I added 2 MA500 monoblocks for my R&L main speakers. You might consider something like the Marantz MM9000 also. If you want to consider other receivers, something from NAD or Rotel might work well.

Your other thread has generated a few additional comments as well, hopefully the moderators will combine these two.
