Clipping with Separates with change of Power Conditioner[?]

I have two Furman Power Conditioners. The one connected to my power amp went out recently. Nothing I can do allows it to work. I replaced with a W-Audio AC Power Filter Power Conditioner - Power Purifier with Surge Protector. I initially hooked up the items for the Furman to the Filtered Plugs on the W-Audio. In playing songs that get to higher volume, the items driven through the Power Amp would go dark while the subs continued to play the tunes.

My Power Amp is Class D [NAD c268 being run at stereo = 80 WPC].  My Pre-Amp is a Naim NAC 272.

Is my assumption correct that this is a power amp issue or compatibility issue between the Power Amp and the new W-Audio Power Filter Conditioner?

What is your remaining Furman?  If it has SMP and LiFT I'd run the entire system through it.

Avoid power conditioners  on amps in general.  Most are not up to the task and are nothing more than a bottleneck.

Thanks for all of your suggestions.

I've ordered a 5 meter power cord to check out the amp being connected directly to the wall. All of my wall outlets have 15 AMP PS Audio PowerPort Classic as outlets within them.

The sensitivity of my speakers are 89 DB, so if the problem persists or I suspect driving my speakers is too much for 80 watts per channel, I can get a second one and switch each to mono power amps with 300 watts.

I will hook up the power cord middle of next week and report back.

My house was re-wired completely in a major remodel about five years ago and the listening space in the living room was placed on a separate circuit with the PS Audio PowerPort Classics installed. It is a 15 AMP circuit, however.

I live in the Olympic Peninsula of Washington State. We had a lightning storm earlier in the summer and it was the first of such we've experienced in over seven years.
