Just a note, if you are playing loud, 80 wpc is not that much for some loudspeakers.
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?

Alpha Audio did live stream testing of multiple power conditioners and found that their success varied greatly with the types of power issues they had at each location and varied with the components they were conditioning. Basically the takeaway was buy with the ability to try and return. Worth watching the video.

@carlsbad2 +1. I get no distortion or haze from high quality wall receptacle. No conditioner in my future. |
I’d just plug the amp right into the wall, as recommended above. 80 Watts of rated power isn’t much. BUT - Class D amplifiers can have very high instantaneous peak power & current demands, and your new conditioner may be limiting this - perhaps the NAD’s protection circuitry (more likely the Hypex module circuitry) doesn’t like these conditions, hence the shutdown. When running an amp, you want a power condition that is NOT "current limiting". But frankly, I often find it best to simply run amps directly off the wall (if available). I’ve never had a problem doing this, and feel that most of the supposed benefits of expensive power conditioning are way oversold (and I have a Niagara 7000). Ironically, if your amp were class A it would have a continuous constant power draw, no matter the signal level. |
I’m a big believer in isolation transformers. Really clean up the sound. I use a large 20amp Equi=Tech balanced isolation transformer unit for my preamp, etc. I would still plug my mono-block tube amps directly into the wall until I found a couple of 8 amp isolation transformers to plug each in to which has worked very nicely. Just sound cleaner. I also have a couple of smaller (5amp) isolation transformers that I plug all the little wall warts, etc into the power the network switch, light, turntable, etc. This keeps digital crap from getting back into the line. |
