So if this is No Volume Adjustment, what is the effect on playback volume? I can play most m4a's made by iTunes (from CD) at 100% when my receiver is connected directly to the amp. Some CD's (Live at SXSW by Thomas Dolby and the Jazz Mafia Horns) are really loud and drive the amp to protect. p

Clive, I hope I understand your reasoning. As I understand it, this means that with an album peak level of 0.9, the positive gain will be at most 0.92, even if the RG of the album is +3. It is an extra explanation (besides the ones I already gave) why RG settings will not always have the desired

Thanks Teus. I couldn't ask for a clearer response. I'm really surprised I haven't seen this discussed before. Everything I've read previously pointed to having Squeezebox volume left at 100%. I've set mine for 95% and will see how it goes. Thanks again. Bill -- lasker98

It does affect the sound quality, but so little that it should be totally inaudible. It just adjusts the volume in digital domain and causes noise in the lowest bit(s), but that is below the hearing threshold. When you tested, did you compare with identical sound levels? The louder always
