Musicnoise,
You can do that - but you will likely need the 20 db attenuation - you can verify that you are not overdriving teh pre by using the volume control on a loud loud CD track and see if you reduce distortion by reducing the volume.
You will lose the benefits of balanced XLR if you go to a preamp with only RCA (although the difference in most cases may not be audible but could be a significant factor on long runs).
