   that might be the case, I see the signal being at about 20-40%, 
compared to about 50-70% 'normal' signal (in vu-meter).

   the big Q remains - what do I do? (I didn't try the headphones output 
yet, but everybody says that headphones output on the consumer receivers 
is of poor quality (then again, I listened to it via headphones and it 
was good enough for me...)).
