Clean power and it's affect on sound quality

I have two dogs and one is black and the other is golden. Whenever I listen to music I only listen when the Golden dog is in the room. Remarkable how just when he moves around the room things change.  The mids are more detailed and the high-end is softer absolutely lovely. When I listen to hard rock 'n' roll I invite the black coloured dog back into the room.

My speaker’s face west -.probably why the Dead & the Doors sound so good……

Well, the OP’s posting was long overdue. People just don’t understand the physics underlying power delivery to handheld remotes. It’s easy for the proudly ignorant to pile on, but the OP raises real issues that, FYI, have been the topic of research published in the Stanford Journal of Electrical Engineering. This may all sound incomprehensibly counterintuitive, but there is solid physics behind the OP’s observations. I’ve clearly heard the same sonic transformation in my own house. Google w/broadly general search terms along the line of "dielectric filtering and electroacoustic intermodulation in free-air transmission of battery-powered control signals."

Related: Without electronic assistance, I’m completely deaf. But I found that switching to solar-powered batteries in my left-side hearing aid restored my ability to perceive a truly holographic soundstage from my Wilson Alexx V’s. This was especially impressive considering that I still could not hear a large portion of the nominally audible spectrum, say, from 60Hz through about 9KHz.

But even more remarkable was the fact that, when I swapped in the Tesla X-Series photovoltaic batteries, my left ear’s response became ruler flat from around 9500 Hz through 40KHz (no, not a typo!). In fact, when listening to 192/32 recordings, the imaging became rock-solid, despite my being able to detect sound in only one ear.

So don’t mock until you can fully duplicate the OP’s test conditions. I hear rumors that Synergistic will soon be marketing modestly priced inverterless-solar handheld-remote batteries for well under $1000, an expense within any audiophile’s reach.

This has been a truly remarkable conversation.

The power grid supplying my house is fed from a nuclear plant.  No wonder, regardless of how I upgrade my power supply or cable, the effect is not notable.   

The only gear I have that uses a remote is the CD deck, but it (the remote) has been setting in a drawer, sans batteries, for 20+ years because I do not like remote controls.

Will that remote be OK, or should I purchase other/additional remotes and stuff them with solar-rechargeable batteries?

If more "stuffed" remotes are better have you performed a "stuffed remote" shootout to blah, blah, blah?
