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.

Since my new Onkyo A-9555 integrated took about 130 hours to fully (or nearly fully) break in, I am loathe to turn it off. But the cool thing is that when it's idling, being class D it draws only 0.3 watt! So I just leave it on guilt-free and it's always ready to go.

I thought this thread was going to be about transient speed, and the Onkyo is quick and articulate as well.

It is only normal for SS to be slower to reach thermal equilibrium since they generally don't consume as much power. However, my experience with Gryphon Class A amplifiers is similar to tube amps: super hot in no time! Class D amps are at the opposite end of the spectrum.
This has definitely been my experience. I got in the habit of keeping my high current SS amps on all the time, and am unsure how much that might have contributed to my electric bill. When I got in to playing guitars into tube amps, I was surprised how little warm-up time was required to hear the difference in tube swaps and the like.
