Contact JRDG. A moderate amount of clipping should not cause the amp to shut down. I have a 112 and have not encountered this problem (driving Martin Logans).

The JRDG should not have shut down. The N802 has a 3ohm load on the woofer, which should have allowed the JRDG plenty of power (I believe it doubles into 4 ohms), at this point, the N802 should not have pulled too much.
The Martin Logans (wonderful speakers) are probably much more difficult to drive than the N802s.
Well, I've spoken to a rep. at Jeff Rowland and his reply was that the "breakers are set very conservatively" to protect any speakers and the amplifier from harm. He further elaborated that I can send back the amp and have them install a larger circuit breaker to allow the amp the ability to provide the speakers the power it needs without setting off the breakers. I know that speakers don't use all the power from an amplifier all the time but my concern was whether this change in the breakers would cause any damage to my speakers. He assured me it would not. Does this sound right to you?
With regard to the 802's impedance it's a basically a 4 ohm speaker. I have measured mine and I think DB Keele did a review of the 802 in Audio where shows the impedance as well. Basically the speakers are a fairly demanding load between 60 and 500 Hz where it averages to about 4 ohms. At it's lowest it's just under 3 (about 2.7 ohms). So if you are playing material that has a lot of these frequencies you are essentially driving a 4 ohm speaker. The 802 demands current - lots of it. With that in mind I think 112 should be able to drive them. I have an Accuphase A-50V and it's drives them very well indeed.
