I have DSP disabled. I believe that fully open with all features enabled, the Nucleus+ can pull about 90w.
Sound is improved overall. Both the streamer and my DAC are running off a Bryston Balanced power unit (on a dedicated line) so they should be getting pretty clean AC. Some of the improvement could be from removing the switching PS which might have been throwing noise back into my electrical mains? I would think my DAC would be so somewhat immune since it has an outboard PS that weighs about 25lbs but who knows?

Pete,
I am surprised about how little power it draws, that is 7.6W. Of course, if you turned on DSP Upsampling the CPU will start working harder, but for a streamer you don't want that (and kind of defeats the purpose of a NOS DAC). I would say that it doesn't pull much more power than a Pi.
I think the power supply changes are usually subtle unless you have a really poor PS you are using. For instance, the el-cheapo 5V/3A DC LPS powering my JCAT USB card was significantly worse sounding compared to my SBooster 5V supply when I switched to it. It was not subtle. The cheapo supply was running really hot besides, I cannot think that powering an USB and Ethernet card would demand the power it seemed to be delivering. The SBooster is cool in comparison.
