A further update; not so positive this go round.
As the air conditioning season has started in New England an unwanted feature has occurred. When the AC ( central ) goes on, the LPS is faltering and the music stops to be replaced by static. Our AC and my stereo cabinet are on different circuits. This is a very reproducible event and does not occur when I go back to the wall wart power supply. I did a bit of research and came across a couple of solutions: a hard start kit for our AC, vs a UPS. Of course returning the unit is also on the table. Any suggestions would be appreciated.
