When the power conditioner fails without a bang

I imagined that on connecting the A-E device at the time that there was an improvement. Right now I cannot remember, since it was 2018. I had a few music-lover friends around and we came to the conclusion that while the improvement was slight, there was certainly no degradation

The main aspect of the A-E device is protection.

The Lessloss mains cable I got from a friend who bought a 2.5m length and found it too short for his purpose.

I looked at the response graph using an UMIK-1 microphone and mini-DSP. The noise floor is some 2db quieter
