I think I'll just have to build and test it... single ended B1 -> non-inverted single ended B1 -> inverted single ended B1 -> non-inverted+inverted The concept of an active ground channel is tempting compared to the standard solution of just "dumping" the signal to ground :-)

Will this work??? I use a Nelson Pass B1 pre-amp/buffer... and was thinking of making a head-amp for my new AKG701... Can I make a push-pull amp by using two TPA6120 chips to generate a inverted+non-inverted signal for each channel from the single ended B1 buffer? There should be no...
