Hi @anon56814208 ,
My Nova, 18 months old, appeared louder on the left channel than the right when listening half way between the speakers. Most vocalists/news readers etc. were right next to the left hand speaker & not centred between the two.
I wondered if my hearing was starting to deteriorate, due to age, & had my ears checked. There is the beginnings of ‘treble roll off’ which is worse in one ear than the other but not enough at the moment to make a lot of difference between each ear.
I therefore wondered if the Nova’s zero channel balance control had been factory set incorrectly & found that, in my case, an adjustment to +2 on the right channel centred the image on my test LP & CD, & that there was, unsurprisingly, a very noticeable improvement in sound quality.
Whether the Nova wasn’t calibrated properly or it is my ears does not really matter. The balance adjustment has done the trick & it is not worth the unit going back to Salisbury for investigation of a possible issue.
I assume it was the Nova as, using headphones, for which no balance control is available, the stereo image is dead centre. It therefore wasn’t my ears, reduced treble or not.
I assume there is no balance control for headphones as, obviously, sitting on your head, they are always in the same position relative to your ears whereas you can move in relation to speakers & may need to adjust the speaker balance to allow for a non-optimal listening position.
Hope this gives you some food for thought.
