We've done something *like* this for the last- 29 years? or so... (of course we got rid of the output transformer too). What we found was that to be effective *every stage* in the amplifier had to be summed in balanced mode- in effect every stage had to be differential.
The North Audio sounds like its a push-pull amplifier. If I recall right Luxman made an amplifier that would have to have had a lot of similarities back in the 70s. It even had a triode output.
