so pars posted this.


all sorts of wrong. lets start with the fact that current output D/A converters really like driving a zero impedance. 27 ohms is not a zero impedance. So with +/-1.2ma you get +/-32mv and then you use the tube to amplify the crap out of it. Nope, definitely not the way to do this. All sorts of noise etc...

a while back there was bakoon and audio-gd pointing fingers at each other as to who designed satri and when.

so here is the satri version 4 circuit


and here is how audio-gd turns it into both the I/v converter and acss current output and voltage output (one at a time, not both)


performs better than anything else I have seen

ideas in progress as work on the ultimate dsd/r2r dac :D
