Thank you. One more related and probably more complex question....does my solid state gear benefit from a warm up period, or is it just on or off?
To me, this one is a little bit less clear-cut.
The measurements may change (ever so slightly) as the devices heat up, but I highly doubt it is audible.
Here is another question, food for thought: Do the electronics technicians allow their SS instrumentation to heat up before taking valid measurements?
See, here's something to keep in mind--Audio circuitry and audio reproduction is fairly mundane as compared to other electronics and circuitry. The more interesting and more critical electronics are found in Chemistry and Physics Labs, in the Electronics Labs, and in the medical fields. Ask yourself, what is done in these other more critical fields? If fancy cables and break-in periods are not needed in those critical fields, then how could they possibly be needed in the mundane audio field?
