I will be changing my Sony ES receiver to a Marantz AV 8805 and a MM8807 7 channel amp (150 rms).

I am contemplating adding a MC 303 for the front 3 speakers. There is not much in cyberspace about these amps except for KR’s brief but positive account. There are some reports of how great it works as a stereo amp due its robust power supply.

Does anyone here of any experience with this 155 pound behemoth ?
I would think it would sound much better then the Marantz amp but any first hand experience is most welcome.

Thanks in advance.

There was a brief moment where I was using the MM8077 to power my 800D3 and HTM1D3. I knew it wasn’t enough, but it had to do as this room has been a project for the last 12 months.



The upgrade to the MC303 was great and immediate over the MM8077. I’ve been using the pair of 303s for the last 6 months and if this all I ever had I could be content. But when is content enough ;)



I have read that a dedicated 20amp outlet and this amp is capable of 1000 watt peaks. It’s on the roadmap.



Ron C has stated the MC303 amp is capable of keeping up with bigger monos.



Could it be too much for those in-walls?

I had a 303...great amp. BUT be careful if buying used. Mc had a quality issue with a run of them.... Mine overheated due to some defective “Motorola board” issue. If you buy used, be sure to check with Mc if the serial number was part of the bad batch. :thumbsup:

I had a 303, it was great amp, and very impressive looking. I replaced it with 3 Parasound JC-1s. Not everyone will have room for 3 mono blocks in their racks, but they bested the 303 in every way, and for less money.

BTW what does need have to do with any of this.
