My Neumann/Bryston combo sounds perfect right from the beginning.
No need to waste resources.
I agree it is a waste of resources...
But for me, critical listening is a big part of this game, I most definitely hear the difference between a cold and a warmed up component.
I find my systems sound begins to come together after about 5 to 6 hrs. of warm up. I need the system at a reference point every time I evaluate a change I make in my speakers or I find I am just chasing my tail. Or if I am auditioning them for a potential customer I want the setup at its best. There is promise with class D in this regard...low power consumption and good sound I have heard from amps like Arion Audio.
I should try to curtail my amps on time for the environment and my pocket.
Of course there are many other things we should be doing to change the sorry state of our environment...revamp the auto industry, the public transportation infrastructure, energy generation and consumption, wasteful packaging, and first on my list...politicians that gladly sacrifice our land , air , water and a healthy future for our children, for money and power. "It's good to be the King ! ", to quote Mel Brooks.
Oh SHIT.. there I go, starting a biased political rant...wrong forum for that !!! Greg
