Tube vs. Solid State Amplifiers


I found this really good link regarding the differences:

I've heard some (who are much more knowledgeable than me) say that a tube amp and solid state amp which are rated at the same output power in practice will not drive a speaker to the same level, that in selecting amplifier power levels, you would get similar results from lower powered tube amps.

I thought it would be interesting to see what those who know much more about this subject would contribute to this discussion.

@goofyfoot , even if you were in the market it's extremely unlikely I'd be involved in any transactions, as for one thing your use of the term "valves" makes me think you're in Europe, and I'm in Texas.   But if I can ever potentially help with speaker matching questions, feel free to ask.

I bought my Audions direct from Alberto. Had nothing to do with OCD Mikey. You don’t want to see what the fuss about is, your choice. Meanwhile those who know by direct experience, know exactly what I’m talking about. These amps are a game-changing experience to golden ears. If they didn’t so ‘rock my world’ so to speak, I would have returned them without regrets. I have no time for hype as this is serious money. That said it’s worth every penny. So good I’m actually upgrading to the Gran Vivaces. Happy Listening :)

The differences between tube and solid-state lie within their circuits, featuring different components depending on the design. Tube amps work through voltage, needing an output transformer to convert it to the current running throughout the wiring and finally into the speakers.

Solid-states are driven by current from the output devices, so they typically have a single power transformer and silicon transistors – offering a cleaner and more detailed sound overall.
