Indeed - thanks for that link Phil :thumbup:

If only a few more of the hi-fi brigade would employ some solid engineering principles like yours, rather than rabbiting on about the night and day differences they heard after plugging in a new shielded mains lead :headbang:

Someone mentioned video earlier and it is probably easier to measure video signals than listening to speakers.
I was always taught to run cameras (even digital cameras) for a couple of hours to get them to a stable operating temperature before lining them up. OK, this may have gone back to the days of analogue tube cameras, when in the studio at least they were left running 24/7.
Also, when commissioning new 'glue' equipment such as distribution amps, we would indeed 'burn' them in for several hours or even days. This was for a different reason though, based on the idea that if such equipment were to fail, this would happen very early in its lifetime.
