I cant help myself so here I go...
This old argument about tubes or SS does drive me mad.
I have heard a few great sounding tube amps (ARC, Lamm, Audio note), but they always have sonic problems. Some almost worth putting up with, but still ultimately annoying. SS amps too. Then finding the right speakers to match etc.
I heard some Atmaspheres which sounded very good by the way.
Cant we have an amp technology that just works? Its like buying a car that goes great around corners, but just wont go in a straight line unless the road is made of a special concrete and not tar!
If you like a characteristic, say a type of tube, lets just put that software in. But the amp its self having no "sound" but will drive any type of speaker with no distortion or noise unless asked to. Oh small, cheap and efficient too!
Lets all start praying.
