As to comments about SS gear taking more than a minute after power on to stabliize - whether temperature or otherwise - that should not happen. If you have equipment that does so then, whatever you paid for it you paid too much because it is very poorly designed. Having designed and built more than a few amplifiers, and worked with a wide variety of applications of manufactured electronic equipment - this just does not happen. As to audio gear - I have never had a SS item that exhibited temperature stabilization problems - from Yamaha recievers through Mcintosh amps. Indeed, the last time I saw a piece of properly functioning electronic equipment that required any amount of time to stablize was thirty years ago - a black and white tube tv. Actually, one little 'trick' to see if you have connection problems on a pcb is to spray different areas of the board with freon (or now Gore friendly freon) - there is never a change in the functioning of the equipment or the waveform observed on a scope unless you hit a bad connection - you can spray a transistor all day long and you won't see a difference - this of course is with equipment that was designed and built by someone who knew what they were doing.
Your fast is your amp f rom 0-60 .?
I have noticed that there is a very noticeable delay in my DA-60 Jadis integrated before it will utter even a muted distorted mumble never mind sound good. The time always seems too long. There is no doubt that the automatic biasing mechanism which I see as being a single voltage delivered to the filaments of each tube and does not employ any noticeable feedback regulation. This type of biasing is not true bias but an automatic voltage level delivery system circuit.
The true turn it on and watch the amps bias based on the output for any given input level can be seen in Woolcotts and Audio Valvle for instance.
The Slow/soft start my amps go through is merely a protection circuit as best I can tell, to ensure that electrical inrush is muted and it must go through a slow, stepped up, variac like start.
My other amps Cyber 800 Consonance monoblocks again declare it a self biasing amps but the tubes this time warm up from that ice cold distorted sound to tolerable in less than a minute the Jadis is about 2 minutes. I am not going to touch the optimal time to good sound. In terms of plain old listenable sonics how fast do your amps get up and smell the coffee.
