It seems to me a strange thing
Mystifying
That this holy, immaculate signal is so carefully taken care of and then sent to that musty obsolete tech and then into high fidelity headphones for evaluation of how well the tubes mussed it up
And that this practice is
A fashionable hobby?
[Don't mind me, I'm just old and completely out of touch with what cool people do these days.]
I think
@MattHooper sums it up for me. It's about tangibles of physically swapping tubes being more pleasurable than something being done on the digital side. If I'm gonna be honest, even just switching from Midgard to a SET amp with hundreds of thousands times more distortion provide
barely audible difference to my ears (i.e. I would probably fail DBT more likely than passing it) and they're mostly fine tuning the harmonics within the sound to a very small degree. DSP effects would actually
be a lot more audible than just switching from a SS to a tube amp especially when you're using a linear impedance headphones like DCA Stealth, Susvara and other planar magnetics. With dynamic driver, impedance and damping factor difference between SS and tube are the main drivers for differences and rolling tubes would provide barely audible differences (other than amplification gain levels) when level matched (as long as the noise floor such as humming and hissing aren't audible).
What I still don't understand deeply is that why would a
very small heck even just imaginable change in the sound perception through listening through tube amplification (not looking at measurements) become more pleasing, gives me a psychological perception of a more relaxed listening session? I chalk it up to this weird sighted listening when looking at tubes and the nostalgia of "vintage-ness" honestly.
I agree. The idea of doing it via digital modelling takes the fun and romance out of it, for me. I really got a kick out of getting in to tube rolling a few years ago. Am I just imagining things? Could be. But it's fun, and I just find different tubes kinda neat, and tactile, and I love the visuals.
I get why others would go the digital modelling route.
This. The visual bias perception, heat and glow and its ability to fine tune the harmonic distortion with tube rolling influence us way more than the sonic attributes when comparing SOTA SS amp and high distortion tube amps. Digital modelling eliminates that tangible trait and puts my mind into "working mode" rather than "relaxing and fun" for some reason.
On a serious note, sonically, I don't have preferences between tube and solid state as I have both modern and obsolete tech and I listen to my SS amp at work and tubes at home, but the visual cues of glowing tubes when I'm at home seriously influences my listening experience to a better degree
