All gear takes time,tubes more than ss.I'm a tube guy and I usually turn the switch about an hour or 2 before settling in.Kinda like decanting that treasured red wine.New equipment all depends,JRDG Capri owners suggest 500 to 700 hours of burn in and that's solid state.Equipment with V caps average 500 hours.Other than Magnepans,many weeks,I don't have an estimate for speakers,or cabling.These numbers are based on my experience on my system,and should not be interpreted as an absolute. |
A lot of variation here. My experience with a variety of tube amps, is about 30 minutes to 1 1/2 hours. Break in is another animal altogether, 100 hours minimum, as Markwtkiss suggests, this can run up to 500 hours plus. |
I have all tubes...One hour as a rule..........Break in depends,but expect 100-200 hours ( could be less )........ |
It takes less than 30 minutes to break in a new vaccum tube.
There is no dielectric.
This has been discussed at length in a couple other threads.
Warm up for tube amplifiers averages 20-60 minutes. |
As to a solid state amp if you have measurable or auditory changes in the performance of the amp after it has been on for 2 seconds, then you paid too much for it, whatever you paid. A design that is that unstable with temperature is not worth the paper the schematic is printed on. As to tube amps, perhaps a little longer due to the heaters. What does happen is the listener gets used to the sound, the sound doesn't change. Same thing for speaker break in past a short period of initial use - less than an hour. Cable break in is ridiculous - but a good rule of thumb is just past the time for the warranty to expire. |
My old Rowland 7M monoblock furnaces take about 8 hours of playing time to stabilize sonically and yield their best when starting from standby. . . . more if you turn them on from totally off-cold. Current cool-running JRDG 312 takes longer than 7M. . . couple hrs playing after idling in ON position overnight; a day when bringing online from idle; couple of days when starting it from long off-cold. . . . admittedly, I am anally retentive. . . or delusional as some may suggest. |
According to Pass Labs they recomend at least 1 to 1 1/2 hours for there amps to get up and running. |
"but a good rule of thumb is just past the time for the warranty to expire." Classic!

Warm up for an AB amp is usually 20-40 minutes. For a Class A amp, it can be much longer. My experience is tube amps usually warm quicker due to the direct heated nature of most triodes. I find my amps are warmed after about 20 minutes. It is audible and obvious when they cross the line.
Break-in of cables depends on the brand. Clarus burns things in for a solid 200 hours. Others may be longer or shorter.

As to a solid state amp if you have measurable or auditory changes in the performance of the amp after it has been on for 2 seconds, then you paid too much for it, whatever you paid. All components on a circuit board are rated. Those ratings are established once they have warmed up and stabilized from a cold turn on. Once they reach that optimum operating temperature range, then it works as intended, and that takes a lot more than 2 seconds. Same for tubes. All the best, Nonoise |
Sounds great after “on” for 20-24 hours, also on and warming up are the preamp, CD player.
After 40 hours, the difference is astounding, there is a laserbeam 10 feet wide wall of sound, where the vocals, and especially the midrange and small 6.5” woofers, mesh perfectly and still give me goosebumps, on arms, and I love when my head tingles!!
If it’s snake oil, it’s very good snake oil!
Speakers took about 300 hours to relax and really shine, a lot of people don’t allow break in for speakers…
I waited the manufacturer recommended break in period, and I was rewarded greatly!

I have solid state....don't turn it off |
I find my First Watt amps sound noticeably better after about an hour or so. My Monarchy Audio monos take about the same. |

I was a Calibration Specialist in the Army (man that was a long time ago...), using reference level equipment to calibrate lesser-level test equipment (O'scopes, Distortion Analyzers, Volt Meters, etc.). I'm sure the reference level gear we used was pretty darn expensive as was the level above ours that was used to calibrate our gear. The first step in most calibration procedures was "Turn the unit on and wait 30 minutes." |
