Four Hour Tube Amp Warm-Up

My Mal Valve 2 and VAC 300.1 have a good sound after 45 minutes. After 4 hours , they sounds amazing !

It took my solid state equipment 4 hours to sound its best.

My current Primaluna Evo sounds great in less than an hour.

It could be equipment that's in front of the Primaluna that needs more time.

But certainly my sense is that tube gear hits its sweet spot sooner than solid state.

My tube amps seem to warm up pretty quickly...10 to 20 minutes maybe? My Pass XA-25 takes about 45 minutes although it sounds damn good immediately upon start-up.

PL Dialogue HP Integrated here. Sublime within 15 minutes of power-up. 4 hours? Sounds like your confirmation bias needs adjustment!

4 hours -- wow. So, tube life is, in effect, one quarter of their expected life for good listening? That will sound like an argument for solid state to many.
