With my SITs driven directly, a source impedance of 600 ohms gets you to
-3 dB at 100 KHz.

I think the Sony parts are comparable, but I haven't measured them.

So, tell us, how does it feel to say "with my SITs"?
I'll bet there was a big smile none of us could see

you mean on bias referencing resistor , or what ?

"input resistor" is somewhat tricky to grasp

exactly Zen Mod, the biasing reference resistor!

Nelsons answer is in this point not clear for me.....

Generg,

Going thru the question and answer related to Nelson's answer above, I think he mistook your 100k for frequency(Hz) instead of the 100kohms that you meant so if you clear this up we might get a better answer.
