Yes the volume is digital(in 24 bits) so 75-100 it should be normally, correct attenuation would be so that 100 volume is as loud you ever want it to be, but not louder . With rothwells ( I have a bunch of them) or other suitable attenuation you will be using the digital volume control in it's sweet spot and if you go lower, well the volume will then be so low that you won't hear the "loss of resolution" , but correct "gain staging" is a factor between any audio device. Many people reports excellent result getting rid of the preamp :) Attenuators will also protect your speakers, as most squeezeboxes can have very very rare bugs when they output something at full volume suddenly usually horrible noise, beware. -- Mnyb -------------------------------------------------------------------- Main hifi: Touch + CIA PS +MeridianG68J MeridianHD621 and assorted amps SiriuS, Classe' Primare and Dynadio speakers, Contour 4 Contour Center, and Contour 1.3SE for the rear ch.
