I had recently a brief discussion with John Broskie and he gabe me the hint, that construting a poweramp without driverstage is the trick, so that the linestage directly swings +-35v. Well, I am not yet sure how you would do this...an Aikido with this voltage swing ? currently I use his unbalancer with a 12au7 doing the upscaling of the small signal from the sabre dac 9018 to something like 2 V. But 35v ? 70v p-p ? Would this not result in another stage in the linestage simply ? I guess it only makes sense when you can save a stage and get rid of coupling caps etc...
