Nested feedback-modulating tail current idea

Hi all
I've just came up with this (schematic says for itself).
Looking forward to your comments and suggestions.
regards

here it is:

Hi, Darkfenriz,

Nice idea

Is it the same with this? R7/R6 = R17/R3

thank you
the idea of tail current modulation looks the same, but I take local feedback from VAS and global from output.
In your schematic there is a current mirror, which makes tail current less important as far as amplification is concerned.
regards
