We use negative feedback in audio amplifiers to stabilize the gain, increase the bandwidth,lower the output impedance and lower the non-linear distortion.

you have to listen yourself to a real tube amp para mawala ang "daw", which is synonymous with doubt ;D ;)

Playing a piano oftentimes uses two same notes/keys where one is one octave higher than the other. And this sounds good. And this is what is produced by second order distortion that tube amps produce. A warm sound.
Maybe this is where the magic comes. Same with orchestra voices, same notes, and the blending sounds good.
Generations come and generations go, but the world stays just the same. What has happened before will happen again.

...and add to that the emotion an artist or singer projected towards the listener, it cannot be heard , it is rather felt, others call this character of tube sound "palpable presence" :)


That's True, even when you're listening to Tube FM radio, you have a feeling that the DJ is infront of you.

Hmm..title states "advantages" nice to hear adjective praises for the tubes  ;D

Ilan sa mga nag-comment ang nasa 20 below age bracket?...ahehe joke lang po  ;D

I, also kept on wondering why tubes is coming back I thought it was being displaced by "less is more" tech.
I only see one heck of a reason as an advantage, "popularity". When it's popular it's in demand...just a thought though... :D

if you're 20 below, tube is a complete alien thing ;D
perhaps there is a reason why it is popular, objective listening is the key, sir tony was right, after you listen you decide, then perhaps a more in depth reason for the "popularity" thing :)

when i want to travel back in time, i just let my triode SE glow for about 10 seconds, switched on the B+, select "Remember When" by the Platters, sit back & close my eyes 8), who needs time machine anyway.... ;D

Tubes are more forgiving that solid state devices, once i accidentally put a 12vac heater voltage on a 6.3vac heater and after noticing that it really has a bright glow i power it off then check the wiring then put proper voltages and its still works nicely.

I like the tube glows.....especially the bluish ones...but some put a blue LED on base to imitate blue glow...

^and design considerations are entirely different.....in hifi amps, distortion is minimized, in guitar amps, distortion is encouraged and desired....
