.......about Fet-ishizator......

I did exactly, step by step, all described by Mr Fikus in fet-ishizator issue but it has a very low gain.....too low to fit a single TDA1541 output! even if you work on the surce resistor or input resistors to obtain a higher gain it's too low....... and distorsion is really audible ...too high to achieve a good result!
I found very pleasant to use Fetishizator as output buffer after I/V conversion stage, in many DAC !
