Thank you for your support on debugging Romy. When I had the soundsmith and encountered the problem, Mr. Lederman tried to help me and we did something along your lines. Rather than digital, we did it with his sg200.
mains-->PP-->sg200 (input shorted)-->power amp-->speaker (The faint noise was there. When the input was not shorted for the sg200, there was more noise)
The noise is only absent when the unit is on battery mode and the pp is unplugged
I did not try lifting the ground of the amp when connecting to pp. So I will do that as well.
