I moved around things a bit today. Things seem to have moved more than I wanted.
I have a habit of turning up the volume to max before connecting my amp to the speakers. The amp has VU meters (Accuphase), so I can detect hum by watching the needles. Sure enough, if the needles move, and I connect the speakers and again slowly turn the volume up, I can hear the hum.
My normal listening position is 9' o clock. Arond 10' o clock at times. At this level, the needles don't move. More than this drags the needle up to -40db, then -30 and at max volume, around -25db.
If I connect the speakers and listen, I can detect the hum at -40 itself, and there is no need to take the volume beyond 12' o clock.
If I keep the volume at the usual level and listen, then the sound seems quite OK. The TT is a Garrard 301, arm is SMEV, phono is a DIY (which till now did not hum, and all this is since I moved stuff around).
The question is - does a properly set up deck have hum beginning sligtly about normal listening positions?
