How much does volume matter when breaking in amps and cables?

My Class D amps take about 48-72 hours to warm up. I don't know why.


All that needs to happen is for them to be off overnight, and I have to wait for them to sound their best, so I leave them on, but not playing.


To me, this would suggest it isn't a matter of break-in as much as warm up.


My current warm-running linear integrated on the other hand sounds great as soon as the music starts.

I’m not buying the everything sounds bad on audio show day 1. Most manufacturers bring demos that have been used in other shows, etc. previously. Many are in fact the first run components from the first batch of manufacturing and ran thru various testing procedures. Now, a “melding” with the other components at that show may happen over time... but majority of components have been played quite a bit. Wilson and Bryson are not grabbing newly boxed items from the warehouse for each show or demo. 

Isn’t it pretty to think so? Look, even IF one manufacturer comes to the show with a completely broken-in component, a speaker or amp or whatever, which they actually don’t because they want to show their latest model, and one that’s not all banged up, they cannot necessarily control who else they exhibit with, you know, the guy who provides cables, the guy who brings the Turntable, the guy who brings the CD player, power cord, etc. They aren’t that coordinated, trust me. The best laid plans of mice and men oft go awry. 🐀

True. What you are hearing is not break in. Maybe tweaking as the show goes on, crowds, changing speaker positioning, your ears adjusting to the environment etc. 

Only if you say so. 😛
