Subwoofer Causing Amp to Stay On

I have an Audio Note Kit 1 300b SET Amplifier driving a pair of very efficent full range drivers. My entire system is plugged into a psaudio p5 regenerator, which plugs into a synergistic research orange duplex(floating ground). I recently added a pair of Klipsch C-310ASWi subwoofers(ungrounded) into my system via hilevel input, connected from my speakers binding posts. I’ve noticed that now that the subwoofers have been added, when I shut my entire system down, my speakers remain on with a slight hiss or static sound. The hiss will stop, and the speakers will turn off, if I unplug the power cord from the Audio Note, or unplug the subwoofers. I was not having this problem before the subs. So obviously they are the culprit. Anyone know what’s going on here? Old school style amp not liking the newer type amplifier inline? What are my options other than go wireless? Should I go wireless(subwoofer has built in option)? I also get slight transformer buzz from time to time from the psaudio p5, and now that my speakers wont shut up when off, it gets expelled through drivers and amplified into the room.

Are these the kind of subs that turn on automatically when they detect a signal? Or do you have to turn them on and off manually every time?

Most powered subs have an auto on that turns the sub on when a signal is present. If your sub does not have an on and off switch then you will have to unplug the sub when it is not in use!

Some additional questions:

1) Are the tubes in the amp lit up when this occurs?

2) Am I correct in assuming that when you refer to turning the entire system off you are doing so by means of the front panel power switch on the P5?

3) How are the delay modes of the four zones of the P5 programmed, among the six different modes that are possible for each zone?

4) Which components are plugged into which zone on the P5?

5) Depending on the answers to those questions I wonder if putting the sub’s power plug on its own zone, and shutting it off with the front panel function which controls power to only that zone (i.e., touching the corresponding receptacle icon) prior to turning everything else off, might help.
