One can have enough degrees to be a thermometer(I only got two at Case Institute), and they will do ABSOLUTELY NOTHING for the individual's aural acuity, or their system's resolution(just two of many possible variables). My BAT VK-D5 CDP has a, "Standby" feature, that keeps the circuits/tubes warmed up at half voltage(designed that way, by BAT's resident Rocket Scientist, OBVIOUSLY for a reason). My SS bottom end amp, TacT pre, and Phono pre, stay powered up 24/7. My tubed mains amps are powering up at least an hour before listening. I'm certain Julian Hirsch(of Everything-sounds-the-same fame) would be proud of those that can hear no differences in well warmed up gear(or perhaps: have never heard well warmed up gear). BUT- As long as YOU are happy with your system's presentation- HAPPY LISTENING!
the thing that i find so ridiculous about some audiophiles is that you have people, like the one above, who admit that they don't know what they are talking about, but energetically argue their position because "the manufacturer says..." it would be like energetically arguing the existence of the tooth fairy because your parents told you she existed and the "proof" is that you left a baby tooth under your pillow and later found $1 in its place.
audiofeil likewise seems to express an unquestioning faith in the statements of audio equipment manufacturers. the problem with this kind of reasoning is that it fails to ask what could be motivating the manufacturer to give such advice. i mean, really...would you buy a used car based on this kind of reasoning?!?
here's how it works: audiophile makers too often advocate for massive waste for little benefit. here, the idea is that you run equipment 24/7 so that you can sit down and obtain better listening without having to wait 15 minutes. so the proposition is that you would leave the equipment powered up for, say, 20 hours unused so that when you do sit down to listen you can save the 15 minutes of warm up time that you would have to wait if you powered up at the time that you started listening.
