Well, Rudy, it's a personal thing. Low powered SET amps are thought by some to be best producers of MUSIC in the world. It would follow, then, that you would have to have a very efficient speaker, OB or otherwise. I presume that you've heard ALL the tube amps there are and as many vinyl front ends. I mean your opinion can't be taken seriously by very many others if you haven't. And still, it's only an opinion. Do get out more, won't you. Are your tastes in music widespread? Do you like the harmonics of instuments? Like the making of art?
