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.
