My 10i seems to be losing volume... When it was new, we used to watch TV (Sky+) with the sound set around -52db. That seemed to be a comfortable listening level in our 4.5m x 6m room, through floorstanding MA Gold Refs. Over time (I've had the amp for about 6m), the 'comfortable listening level' seems to be getting higher and higher. 50-something db became 40-something, and then 30-something. Last night I noticed that we watched Friends with it set at -28db. My wife has distinctly noticed this as well, so it's not just a case of getting my ears syringed... Before I go through the ENORMOUS pain of disconnecting everything and lugging it back to the dealer whence it came, I thought I'd ask whether; 1) Anyone else has experienced this? 2) Anyone has any ideas as to what the problem might be? Thanks in advance.
