Tubes work best when they're hot.

This may be OOT from what's being discussed, but I've been wondering, how does a tube DAC work exactly? I'm guessing the tube is positioned at the pre-amp section. So, DAC chip => tube pre-amp => either headphone amp or RCA line out. This is just a baseless guess though. 

 

Oh, and on another note, my Silmic II caps set arrived, and it's much larger than the Cerafines (explains how I managed to squeeze all the Cerafine caps inside the casing). I don't think Silmic II got any possible way to be squeezed into the original case. So I'm thinking about mixing them, a few Silmic + a few Cerafine. If I have to mix them, which position of the caps pair you'd say give the most distinct sound difference? I'm thinking of using Silmics for the most distinct position, and the smaller Cerafines for the less distinct position.

Well of course, but this Aune T1 has no huge difference from 2 minutes on to 20 minutes on.  It's not like you are sitting there listening and you are like "WOW, the tube is really warmed up now".  The tube is essentially the EQ in this, it's not the same as when power tubes heat up, it is not even remotely the same.

creatip is right this is how I got it explained. 

 

USB -> DAC -> Tube -> AMP -> Headphone

 

Also I think it's right to say that when the temperature is reached that bring's the max electrons in move it will sound the best,

Thank you, I've been wondering about it for some times now. My logic is, tubes are analog devices, so it can't be used to handle digital signal. Meaning it can't be used as the DAC itself, and it can't be positioned before the DAC (because the signal would've been still digital), so it gotta be positioned after the DAC chip, but before the main amp.

 

Well, that's my logic, but like I said, I don't have anything to back it up....

It's a tube, tubes just work better when they're hot. It's just how tubes work. I don't know what else I can say, they're tubes.
