Now I see your points more clearly! Yes, it is unlikely that I will ever use my attenuator near max setting, since my speakers, Aria5/Raven1's are very sensitive, 91.5db. A selector which selects only one shunt resistor each time so that, at each vol setting there is only 2 resistors involved and one contact point, seems to be the best sounding and least expensive control system, that I have ran across. I would need dual selectors for a balance control set up. I am trying to think of some great selector switches to use, can you reccomend some? Also, the formula you provided gives me a headache,>grin<, could you provide the values needed for the shunt resistors? Right now, I am using a Linn Linto phono preamp which has an output impedance of 100ohms. The solid state poweramp has an imput impedance of aprox. 40 or 50k, I would guess. When I switch to a tube poweramp, I guess I could replace the resistors. Are you planning on using a selector switch too? Thanks for your help, Greg
