Ah, Charles, now I understand - I, too, am getting an LPS (from Linear Tube Audio - their LPS+Linear Power Supply). For a moment I was thinking you were inserting a device into the audio chain itself! Instead, you are improving one you already have.
So, we’ll both soon be finding out what an LPS does to enhance the performance of our little CD Boxes.
Another thing: I am finding that sometimes my CD BOX cannot read standard Red-Book CDs which, when I carefully inspect them, are free of fingerprints, dirt and scratches and appear to be pristine. Whenever this happens, I find that shutting off and re-starting my transport sometimes helps. I also have a de-static-ing tool I bought some time ago from Mapleshade in Baltimore, MD, which neutralizes built up electrostatic charges on LPs and CDs. When I click my static-charge neutralizer, it generates a high voltage which jumps across its little terminals like tiny bolts of lightning and neutralizes static charges which can build up in cold, dry winter weather (try walking across a carpet in your stockinged feet and touch a metal object like a doorknob with your hand - you’ll hear a ’snap!’ and feel an electric shock). These tactics seem to work to clear up the problem and my CD BOX is again able to read my CD instead of showing that large green or red "X" superimposed over a yellow CD outline.
