Alpha 03, while tube amps may not be able to increase power into lower impedances, solid state amps will decrease power into higher impedances. Some speakers actually do maintain a relatively stable load. Try running a 16 Ohm speaker with most solid state amps. I think the previous posters got it right. Tubes usually clip more gracefully. Solid state usually can offer more power less expensively. Your choice of speakers and to some extent up line components may have a large influence on amp choices. BTW, I'm more of a ss amp kinda guy.
