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 need for an input buffer (apart from the B1), meaning that the design will be quite simple even if the numerous recommendations from datasheet/posts are taken into considderation
The B1 has an output impedance around 1kOhm
Will this work better than an "active ground" channel?
