Aleph P current sources?

Simplified schematic - how will work?

Here is simplified schematics for Aleph P
with bipolar current sources.
I still didn't made it and I need your opinions.
Do you think this will work well?

Your input source is going to see some DC, so you might
consider caps for that. Also, some nice caps across the
Zeners will take out some noise. Maybe a few hundred
ohms in series with the transistor bases to keep them
from loading down the reference when they saturate.

How would it affects the circuit if feedback resistors R11 and R14 would be removed? I mean, is there a way to get rid off the input coupling caps?;)

I would try connecting R11 *after* C2, and R14 *after* C3. That would give you AC feedback only, but I would expect the circuit to auto-equillibrate with the input gates drifting to ground. Mr. Pass?
