Return it to PS Audio after discussing with them first. I know that power amps can draw a lot of current and that you must be careful to make sure that your power device is up to the task of delivering lots of current during musical peaks.
Power conditoner..
I have a stand by generator for my house. I've noticed when we have an outage & the generator kicks on the lights in the house are brighter. They are getting a full 120v. Because of this I thought a power regenerator would make a big difference in my stereo. I installed a PS Audio Stellar 3 Power Plant & I can't tell any difference. Oh well, live & learn.
