Not to ignore your question ... just some quick questions first. Does the preamp that you are considering have a separate phono input or are all three inputs line level inputs? If the preamp does not have a separate phono input ... does your turntable have its own built in step-up device? On a preamp, the turntable input is not the same as a line level input ... so you will still need an outboard ... just a different type.
