Not with you ... ??You're always gonna be driving less than 5k for low noise due to the loading of the feedback network as well as the normal load.
AD recommends a feeback resistor of 1k and say a 10R resistor to Gnd as well to give a gain of 101. So the loading on the chip will be <1k even for a very high impedance load (like my RIAA network which is 10k ish)
I was just gonna bias the output to make sure the output stage runs in Class A - I thought this was common practice?
I'm surprised to see so many negative posts for something which may well have a measurable/definable effect on the sound whereas some of the other tweaks suggested here will clearly have no measurable effect - surely it's a case of try it and see?
I'm pretty sure theres a few commercial phono pre's (like the trichord Dino) which use this exact topology ....
Anyone got any thoughts???
Joe
