Good small/single outlet power conditioner for preamp.

Anyone know what’s out there? 
I am demoing a very nice preamp but it, for currently an unknown reason, does not play well with my Puritan PSM156 conditioner. The pre exhibits noise/hum from the speakers with any source ICs plugged into it. 
But the preamp straight to the wall is hum free and all is fine. 
If I wanted to keep this pre, straight to the wall is not ideal. So I am preliminarily curious what nice small/single outlet power conditioners are out there for me to consider… 

thanks

@elliottbnewcombjr Im not qualified/knowledgeable enough to do that. If I knew more to what you’re referring to, maybe so… but that sounds iffy for me. 
 

Maybe the new/different/unconventional design of the Puritan filtering system does not jive with the different/special design of the GreenForce power supply in this preamp.

Take a look at the Audience AR2P conditioner - it has surge protection and does a nice job cleaning up the AC.  Should solve the problem with the preamp.

@elliottbnewcombjr yes, the Preamp maker has been very helpful, guiding me through lots of these checks.

I would continue to troubleshoot until you are certain of the problem, then solve that. It will be very interesting to see if the problem goes away when using a power strip only.
