Single Ended Triodes (SETs), the ultimate tube lovers dream.

Re: Thx for the info. I can be patient sometimes...:-).

When I started looking for tweeter amps, i thought on theory that a transistor amp would be best because of specs and above 3Khz, how could it matter? I was so wrong, although all of the amps did a decent job. I still don't know why a tweeter adds so much to the rendition of the spatial presentation.
Class AB transistor: dry, dusty, and flat
Class A transistor: better tone and lustre, but still flat and a little glarey
Class A push pull Baby Sophia: much better space and tone
Fox ASL 6c33 SET: dramatically better space, a but the tone not that great
Agape 300b: Like the spice from the Dune fantasy, opened up space, tone and timbre to make a nice psychidelic breakfast, but lacked some immediacy and lustre.
Korneff 45: not as much space as the 300b, but a lovely melting sheen and texture to the tonalities and authority, like "this is THE tone, accept it."

Another good option is a single ended tube rectified el 84, which I use on the tweeter of my center channel when it is in operation. It probably falls somewhere between the 300b and the 45, although a 300b does that space thing so well. These can be had really cheap, I got a pair of Akai mono pulls from the old tape decks and they sound wonderful both full range and as tweeter amps, $150 and they can be found for half that. They also have a little more power (5 watts) if you are using very large arrays ot tweeters in series.
