The difference when just daisy chaining 2 350's togethor was so small if any, it appears this statement holds true.

However, for whatever reason, the 600 even when powered off and unplugged is still providing resistance or whatever and sucking power from the output of the Denon.


Yep. Remember that the 350 design is different than the 600. The 350 appears to have a higher input impedance than the 600 and it therefore presents less load to the Denon. Although I'm not happy about this, I am not planning on adding a second sub. It does make auditioning other subs a pain in the butt though as they can't be daisy-chained off the 600.

One of the things I've always wondered is how badly just a single 600 may be loading my Denon. I've thought about measuring the voltage at the end of the sub cable when it's open and then plugged into the 600 to see how much it's getting sucked down. I've just never got around to doing it.

Randy, do you, my young Padawan \:\) , feel like doing this? Just stick a Y cable on the end of the sub cable, put in a 50Hz test tone, and measure the AC voltage in RMS. Then plug the cable into the sub, and measure the voltage again on the Y leg that is dangling.

Don't worry...you won't blow yourself up \:\) .
