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

If you plug the new pre-amp into your power amp with no source devices attached (while connected to the PSM156) - any noise from just the pre-amp and power amp?

If so, try a different set of interconnects? Are you using RCA or XLR cables to connect the Pre to the Power? Does the Pre-amp have a three prong power cord or two prong? If all is silent, then add one device at a time and see if one device triggers the hum. I have never seen a Puritan cause noise.
