Clean power and it's affect on sound quality

Been reading quite a bit about how clean power can affect sound quality by segregating the system from the dirty grid with power conditioners, high-end power cables, isolators, and even off-grid battery-powered systems.

I've noticed some changes in sound quality with regards to better power supply, especially with regards to the older house I was in vs. the newly built house I'm in now. The older home had a warmer tone due to 50 years of copper wiring being burned in. My new house is brighter because the copper wiring hasn't been burned in yet.

But one thing I also noticed is that when I recently changed the batteries in my remote controls from your typical Duracell batteries to the solar-rechargeable batteries I use now. The sound quality really improved. Dynamics were improved across the board, tonality was warmer...more golden, like a sunset vs. mid-day bright. The soundstage opened up as well with more airiness and clarity to the instrumentation regardless of my media source. I highly recommend using solar-rechargeable batteries for your remotes vs the standard OEC batteries that came with the remote. I think you'll notice a vast improvement in sound quality - being cleaner and warmer.
