OK.
So, I'm meeting someone tonight to buy a THIRD Kyocera - this one is the top end model R-861. Any input on what I should NOT do? The 451 worked fine with a smaller pair of Definitive Technology speakers and power strip with nothing else using power. I'm not going to plug in the same power strip and speakers as the last two. If this one spontaneously combusts then...
edit) is it possible that the power strip is overloaded? I have a TV, Arcam receiver, PS4, turntable, etc. all plugged into one strip. I plugged in a small space heater with all that gear on the same Monster strip and it blew the circuit breaker and power strip.
