FYI... the latest Slimserver Beta incorporates "Pre-Amp Volume Control" which allows attenuation of the analog RCA outs for DIRECT input to your amp. Bypassing the entire pre-amp stage, cables, etc. yields absolutely pristine sound (even with the native Burr-Brown DAC). IMHO, *THIS* approach is the future gold-standard! (My system... Squeezebox2 into Sunfire Cinema Grand vertically bi-amped driving ML Aerius i's).
