Where's all the noise and distortion coming from?

Considerable noise and distortion the listener hears is produced by things that are not in the audio system. If you could magically eliminate ALL noise and distortion produced by (1) room acoustic anomalies, (2) electronics, (3) cabling and (4) house AC you'd find a lot of noise and distortion is still audible.

How is that possible? Because our hearing mental processes are influenced by what's in the room. We call that extended mind hypothesis. That's what all the talk about removing phones and unused HiFi equipment from the room is all about. I did not create reality.

Why? Physics or Maths depending how you view it - 13th Duke of Wymbourne 19:31:25 08/19/24 (0)

And do what Tom suggests, plot the drain current to be sure the swing is symmetrical - 13th Duke of Wymbourne 10:35:38 08/19/24 (3)
