Four Hour Tube Amp Warm-Up

My Primaluna Tube amps require a 4 hour warm-up in order to enter the Glory Zone. My previous Muzishare X7 tube amp was the same. Just wondering if this holds with the experience of other tube ampers.

After 1.5-2 hours it sounds not bad but not as magical smooth and clear as after 3-4 hours. When I had transistor amplifier Plinius 8200 integrated it was always on. Without couple of days warm-up the sound was hard to listen to.

But if you listen carefully sound is getting better during 2-3 hours. Especially it is true for not feedback circuits. I also paid attention that this difference gets bigger after I tweaked and improved sound quality my 300B amplifier. I had McIntosh MC30 and Marantz 8b amplifiers. All of them benefited from couple of hour warm up. Another fact, in recording studios all used tube equipment is switched on in start of the day and switched off in the end of the working day.
