When were the best tube amps made?

Interesting topic,and I will add more. If the amplifier make the sound more beauty, and it looks like not the real one. I call the declaration of sound. Do you like or dislike? Let me be clear, there is no wrong or right. It is your choice, and I just dislike that kind of sound. Someone do, as far as I know. So it becomes the huge background when we talk the best tube amplifiers.

The question finally goes down with today or past.

When we talk about tube amplifiers, we should  be more focused on music. When we listen the music, what is important? If we are talking about the  enjoyment of the music, and whether matter it is the original sound, then I vote for today 's amplifier. Otherwise, it is definitely belongs to the past.

@larryi agreed.

I can accept KT88,but not KT120,KT150, or more.

Yes! It is ,and  we can NOT make such amplifier even in the future.

The time window has closed.

We all know NOS tube is much much better than the current tube, Some one will argue today's technology is much much advanced than the past, but what we get now with the tube? If the technology can cover it, we will ditch all NOS tube.

Same story play with tube or amplifier.

Year 1967 we have original McIntosh C22 (original C22), now we have Mk V

could  anyone tell  me MK V is better or worse? It is the simple example for preamplifier
