Just found this tit bit of information from Ayre's Manual itself:
"It is normal to listen with the volume knob advanced farther than you may be used to with other equipment.
The volume control offers 1.0 dB steps over most of its range, allowing you to exactly select the desired listening level. To maximize its capabilities, it has been designed so that the volume knob will be between 1 oclock and 3 oclock for a loud playback level in most systems"
