1) ignore the ABR bitrate figure - it is completely meaningless. Nothng is being downconverted. 2) you must have the iTunes volume levelling set, as that is the ONLY way that volume meta tags can be added to your files. SBS reacts to these tags. You can turn this behaviour OFF at play time via the Settings - Player - Audio ... volume adjustment in the Web UI. Using FLAC and avoiding iTunes would be a big step in the right direction to perational happiness :-) - however, from a pure audio quality perspective there should be no difference. -- Phil Leigh You want to see the signal path BEFORE it gets onto a CD/vinyl...it ain't what you'd call minimal...
