    OK, I ran the GR Research A/V-2s for about 3hrs last night (review coming next week), all by themselves, full range to get a feel for them and how hard the 4 Ohm load will push my Marantz 8300. It got quite warm, but not what I would consider "hot". It seemed warmer than it has gotten with my current speakers, which are 8 Ohm. This is just with two of these guys hooked up, and I will be running THREE of them as my front stage. Am I going overboard in considering this as a potential issue long term?

    Should I consider one mono for the center, or two for the mains to alleviate some load or just not worry about it so much? I have a few hundred $$ credit I can use at my dealer so I could almost get 2 MA6100s for the price of one, brand new. The 6100s are 4 Ohm capable.

    I would have thought the 8300 could handle the 4-ohm load, especially set to Small for HT...

    However, wouldn't getting just one amp for the centre channel be a little counter-productive, in that the monoblock might be of superior design (and slightly different sound) than the L/R channels of the 8300?

    I'd stick it out with the 8300 for now. If you get repeated problems with the receiver shutting itself down, then you might want to consider adding a 2ch. amp or some monoblocks.

    If it doesn't shut itself down or give you any problems, I'd just keep it the way it is for now. Although, adding a few 6100's up front might be a nice little upgrade!! [​IMG]

    Hi
    I think you may have expected the Marantz to run warmer, so you thought it did.

    Why dont't you put a cheap thermometer on it. I could be wrong but I don't think there will be much difference.

    I ran it much the same last night, and it seemed to be fine once again. I did not run them quite as loud, and it did not seem to get as warm. It has not shut down at all, but I also want to get rid of that store credit, and there aren't many other things I need from an audio store right now. So it would be a nice little upgrade as well as alleviating the store credit.

    I think one Mono for the center would be a little off. I am actually thinking 3 for the fronts, but I don't want to spend that much after just picking this receiver up.

    Not a bad idea with the thermometer...maybe get one from a fish store...those stick-ons. Center channels 'seem' to be fairly demanding and that'd be the first place I'd stick a mono-block.
