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.

My AN Meishu (SET) sounds pretty good after about 30 min, terrific after about 3 hrs and sublime after 6 hrs

Interesting....I never really thought about it. I think SS amps get up faster than my tubes....but it's just a guess as I normaly have them going 30 minutes before some serious listening. Hey how about How long to put the brakes on? My SS amps take about 40 seconds before the music quits after I hit the off switch.

In 10 minutes my Audionote Kageki amps sound pretty good. But then again, by that time I am more into the music and so it could be purely psychological and not actual improvement I am hearing.

From my experience solid state stuff takes WAY longer to warm up, some taking a few hours before really being at their best. This was not a problem for me because I kept the equipment on all the time, something I would not do with tube gear.
