300B Tube Amps with 15/16 Watts Per Channel?

@dietrdeb 

I wasn't really suggesting you buy the Blackbirds, just that if you do the 300b route I really think PP is best IMHO.  My system is fully balanced from Pacific 2 through to the amp speaker terminals.  It is so quiet that I cannot even tell it is on when idling away.  So I like balanced with transformer coupling, but we all have our taste and needs.   

Ref atmasphere's post. It depends on how much distortion one is willing to tolerate. An SE amp with a pair of 300Bs will not put out 15 watts @1%thd.

I have a pair of triode labs parallel  300b amps.  Made in Japan.  I love each system  I have for different  reasons.  The voice is to die for. It is quick and musical base is there but I have other systems  that are better in that department 

Only one to buy in my mind for higher powered 300B, the Don Sachs/Lynn Olson Blackbird Monoblocks; manufactured by Spatial Audio Labs. Not cheap at $10,000 each, but it appears the culmination is Don's and Lynn's life's work. I do not own them, as they are not in my current budget, but I am lucky enough to get to hear them now and again in my friend's system. I believe they are 24 WPC?

He pairs them with the brilliant Aric Audio Motherlode XL preamp, which I also own
