Here is some gas to burn on this pyre. (I can see it now. I am going to be burned and get poo'd on for these comments)
Vinyl can loose 20% or more of dynamic range after a few plays. This is not good as most vinyl recordings can, at best, only reproduce between 50 and 80% of the dynamic range of the original source when virgin. Some recordings can have as little as 3% dynamic range to start with. Is it good to burn in a record?
In the old days, it was common practice to leave tube equipment turned on full time, even when not in use. Many devices would have different power modes for stand-by and play just to keep the valves ready for action. Today, I keep seeing recommendations to "save your tubes" by turning off devices. The idea is that it takes time for tubes to warm up to the optimum performance level. A sort of burn in?
There are religious factions. Some are deeply committed to each camp. Some are devout because it is popular to be on one side or another and they do not want to be left out of what is perceived of as the "elites". Some are enrapt because of perception, what sounds good to one set of ears may not be good to others. My contention is that many people claim to want accurate sound reproduction, but that they really don't. Solid-state can be too accurate and harsh while tubes can "color" sound with warmth/distortion. Of course, bad design can be found (I want to say everywhere, but will say) in many devices. Some depend only on high prices and fancy/rare labels, but I have seen overpriced and over-rated junk over the years while the simple is often overlooked. The question for me is what do I want and can I be satisfied with it?
"What do you want from life? ... A baby's arm holding an apple." - The Tubes (on vinyl ca. 1975)
Keeping tubes burning was supposed to reduce the likelihood of "thermal shock" which could cause the filament to fail. I remember looking at a tube-based electronic computer (circa 1957) where the machine would ramp the filament voltage of the hundreds of tubes up and down over a few seconds' time when turned on and off to extend their life, because finding the bad tube and replacing it was very time-consuming, and time was money for an expensive computer.
Nailed it! And I'm not even gonna throw in a
, or a
on this one! lol
This is still prevalent in guitar / bass amps. I have a beautiful pain in the ass of a Marshall tube guitar amp that loves to blow cold tubes. But after rolling, it sounds
It's a money pit of grand design.
