Turn-on/turn-off thumps are usually caused by circumstances within the audio system proper, not outboard units...Many things can leak into the audio chain, light switches, refrigerators, AC units and light dimmers. Since you experience this difficulty when turning off your Sony, I believe those things can be discounted.

I understood about the capacitors, the line conditioning was just an afterthought. As I'm still in the decisive stage as wheather its a needed thing or not
