Tube vs. Solid State Amplifiers


I found this really good link regarding the differences:

https://www.caryaudio.com/2018/06/04/vacuum-tube-vs-solid-state/

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.

atmasphere, certainly would like to own an Atmasphere valve amp. Understanding the options better would help in deciding which one. 
Owning 845, 211, 805, 45s EL34s KT88 120 and 300Bs and a mix of Japanese made tube amps purchased from ebay and direct from Sound-gate in Japan.
I am not into Artificial Distortion and syrupy mushy or Lush sounding Amplifiers i find that after sometime i get sick of it. I need an amp that can handle any type of music i throw at it.
Guess maybe if you tried a modern quality tube amp with quality tubes like Ayon, AR, Macintosh, Jardis, Quicksilver, AH Qualiton, Quad or the like you would have found the joy many of us have.

But to each their own and enjoy what you have. 

twoleftears, it’s good to see that linear tube audio is in Takoma Park. It would be worthwhile to visit them in person.

In the smaller amps there are three options- copper foil Teflon V-Caps for coupling capacitors in the amps, additional filter capacitance in the output section (useful for keeping IMD down at higher power levels) and the Caddock resistor option. In all cases these options are available so you don't have to open up the amp to 'tweak' it. We've seen audiophiles do this sort of thing for decades and most of the time (not all) they actually do more harm than good. So we offer the most effective tweaks in advance. The larger amps like the MA-1 have some of the options as standard; the MA-2 and MA-3 have all of them as standard.

I’m one of Ralph’s dealers and also a speaker manufacturer. If by "the options" you mean "speakers that work well with Ralph’s lower-powered amps", that depends in large part on the specifics of the speaker’s impedance curve. Sometimes it is possible to tweak the impedance curve a bit without otherwise affecting the speaker. The Zero Autoformer from Paul Speltz is one way of doing so, and there are other ways which are also benign.

If you have a particular speaker in mind, shoot me an e-mail or a message and maybe I can offer some thoughts.

Eight ohm speakers can work very well with Ralph’s smaller amps if they have compatible characteristics, so you are not limited to 16-ohm speakers.
