Tube DAC Conundrum


I have the Blacknote DAC30 which has 4 tubes in it. I read that digital stuff should be left on for everyday listening, but won't that use up the tube life a lot quicker? I am willing to change the tubes every year if leaving them on all the time will get me that far, but I don't know.

"The issue with digital equipment is that the clocks need to be at thermal equilibrium for optimal performance."
I would hope that modern DACs would not be bothered by this too much, if they're designed right. When a DAC starts processing information, it will start warming more. A CD is constantly changing speed from its beginning, to its end. The data stream is always changing. With all of these variables happening, I'll trust the engineers, hoping they made these things right. The DAC may even change temperature with the different parts of a song being played. I enjoy the music while it warms up.
To answer those questions, the tubes are 6N1P from Russia. They're not expensive to get more (the Blacknote DAC30 comes from Italy). I usually turn it on in the afternoon and off just before bedtime. I think I will stick with that process as it then runs only 33% as much as 24/7.

WTF? You must not understand the clocks then. They do need to reach equilibrium- period. It is how they are made. There is a reason why crystal ovens exist. It has nothing to do with signal(data) passing either.
There is no right or wrong. There are ups and downs no matter what you chose, so just listen and enjoy and do whatever works for you. Be prepared to replace tubes more frequently if you leave it on. An nobody expects an accident. That is why they are called accidents. Those are the things that can really cost you when they happen. So be forewarned.
