It takes music to open up a tube preamp/amp


I'm wondering if anyone else is having the same experience with their tube gear... I have a CJ PV-14L and a MV60. A number of times now I have turned on the gear about 30 min. before I sit down to listen. As it states in the manual.. the sound will improve after 30 min. I initially thought it just need for the metal inside the tube to get warm to lower the resistance. I'm now thinking it takes 30 min of music... I've been digging up some old music I have not listened to in quite some time. For the first few tracks of the first disk I keep saying to myself "I guess this is not a very good recording after all". Then after about 15 min I'm saying hey this ain't so bad... after another 10-15 I'm saying dam this is cool... So tonight I went back and played the first track and sure enough it sounded way better than it did the first time. So are my tubes warming or is it just my brain ?

Have you ever given any thought to the fact that the human ear/brain processor is a very adaptable system and that your are the one adjusting to the sound regardless of what the equipment might be doing insofar as warming-up and, yes, breaking-in are concerned? I didn't think so, because it takes out so much fun factor from audio does it not? I know, I know: you can distinctly hear it so it is there. Funny how you do need positive reinforcement from other audiophiles though. Seems one can never be too sure whether that phenomena picked-up through casual listening actually does exist, right? Can't go all the way, however, and have anything confirmed by a panel using some kind of procedure offering repeatable results. Certainly not as this would go against the central tenet of subjective audio which holds: "to your own ears be true" and its sub-paragraph which reads: "to be confirmed only by other true believers". Yes indeed, electronics that have not played music in a while are out of practice and need to go through the paces prior to the stage lights being shone upon them. Nothing short of music will do. Did you notice that if you are listening to chamber music, a warm-up with any other type of music just does not do it? The soundstage is just not right, the individual instruments cannot be correctly located and PRAT is negatively affected? I have found that if a recording uses a Gibson guitar, warming it up with a recording of, let's say, a Fender, Hamer or Guild will not do it? For the genuine Gibson sound, insist on a Gibson warm-up piece. Equipment is so sensitive these days that you should never, ever say anything within earshot that could affect their sentiments, as the price to be paid is a loss of emotion in its musical presentation.
Newbee, I accept all criticism. I do not think I have denigrated anyone. My tone may not sit well with you or any number of participants for that matter, but I am used to rhubarb. Insofar as your dire warnings go, I thank you for kindly pointing out the fact that some comeuppance may be expected. Difference vs. no difference is all well and good. How one reaches the point where one can tell is the issue. Since I have gotten back to audio a few years ago, the strangest turnaround in beliefs that I have encountered is of this sort: the equipment is very sensitive, prone to great differences caused by the faintest external vibration, by break-in, warm-up, skin effect, etc., while the human ear/brain processor is such a marvellously stable system that any single individual, at any given time, can pick-up on subtle variations by casual listening. I see it in a very different way. As sure as humour affects the tone of my pronouncements on this fine site, it affects everyone listening to reproduced music through a sound system. That is just one unavoidable variable. If you believe that warming-up a tube amp by playing music makes your system sound better, go ahead; you certainly don't need my permission. If one puts this out as a statement and asks for corroboration, don't blame someone for providing contrary opinion. Like a few others on this site, you can decide that I am a nabob of negativism and a nasty, self-absorbed, uninformed, naysayer and curmudgeon and swear-off all of my posts. Since I don't get paid to write these bothersome answers, I will not lose much sleep. So long.
ASA once again your writing and, I guess, thinking, is way beyond my comprehension. Most of your posts as far as I can tell are written in this stream of consciousness language. Briefly put: what the hell are you saying? Sorry if I upset your touchy-feely-higher-plane-and-mental-state side, at least Btrvalik understood that I was not taking aim at him in any personal way. I will not bore you with the heat and kitchen thing as you have bored me with the picking a size thing. Btrvalik you are a good man. I hope you enjoy your system as much as I do mine, and that it doesn't get in the way of the music. Damn it, now I have to look for an audio Guru...
