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

@donsachs I have no doubt that a 24w/ch PP 300b is more than what I would need. I know Clayton's original Spatial Audio very well as I had their open baffle at sometime. The amp looks beautiful and would love to own them, however, its priced out of my current budget (I have other diy projects lined up on the digital side). On another point, I am not sure how important balanced/unbalanced in my system. I have gone through a plethora of DACs in the past couple of yrs and some do sound slightly better in balanced configuration vs unbalanced. The reason why I bring up DACs is because if you have a unbalanced source, I am not sure how beneficial having balanced downstream is. Moreover, in my system their isn't much difference between the two anyway, it more of splitting hairs and I don't run long interconnects.

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
