The volume control implementation in squeezebox hardware is 24 bit I'm quite sure squeezelite is similar. The majority of files you have is 16 bit . There are no true 24 bit DAC's even if they work in that domain the practical resolutions is typically 17-20 bits . The vast majority of recordings you have rarely have s/n ratio that touches 16 bit so knock of a bit or two there to . I USED TO FUZZ ABOUT THIS TO ALWAYS SUGGESTING 100% FOR MAXIMUM FIDELITY , BUT THERE REALLY IS NO RATIONALE FOR THAT IN PRACTICE. If you do as you suggest , adjust the analog volume so the 100% is as loud as you ever want, and use the upper range of LMS volume you dont challenge any limit of the system . And in that scenario even if you do lower the volume to something really low in LMS . The actuall acoustical volume is so low that you could not pick up any loss of fidelity . It can in some cases even have a slight advantage to not use 100% volume, many oversampling filters and similar in DAC's have problems with intersample overshots , this can happen with modern overcompressed recordings making them sound even worse , so backing of -3dB -6dB gives your dac some headroom . But this is not really a design error in the dac ,it's an broken recording , but thats reality . Having better handling fault situations is nice -------------------------------------------------------------------- Main hifi: Touch + CIA PS +MeridianG68J MeridianHD621 MeridianG98DH 2 x MeridianDSP5200 MeridianDSP5200HC 2 xMeridianDSP3100 +Rel Stadium 3 sub.
