I don’t agree with that, but you don’t deserve the downvotes - plenty of people agree with you. I think the magic is in the way the output tubes interact with the speaker, mostly. But you can get the same responsiveness with a carefully designed solid state output stage. It’s just a lot harder. The coupling through the output transformer allows the speaker to push back against the output tube which adds a little resonance and changes the frequency response, to duplicate that in solid state you have to use a complex feedback loop.
- theoka 5y agoI think yours is the most proper explanation in this thread as to why if anything is special about tube circuits. The more sane guitarists will commonly speak of "tube compression" - on the power amp side, coming into play as volume is cranked - being the key attribute that is sought after. It is dynamic and noticeable enough that a non-musician could most definitely tell the difference in an A/B test if given a demonstration. The downside is that all of those 100W amplifiers sitting in hobbyist living rooms often don't get enough power to achieve this without being too loud. The solution is just to buy a smaller amplifier or apply attenuation to the output circuit.
