Based on your post above, we may be misunderstanding one another. When you said "Component and wire burn-in is just a delusion (no scientific or engineering basis). Mechanical things (speakers) can benefit from some use - electronics, no!" I took that to mean that you do not believe in the burning in of new electronics. Your post at 10:24 AM implies that you were addressing warm-up rather than burn-in. If that's the case then we are mostly in agreement. I leave my system powered up 24/7 including my tube line stage and disc player. The tubes live on a l o n g time!
