I had an interesting experience. I noticed a significant difference in soundlevel between my left and right loudspeaker. I thougth this was caused by the fact that one of my loudspeakers is closer to a sidewall and therefore reflections made the loudspeaker sounding ... well ... louder.
I played with the balanceknob on my Nac 72 and I had to turn about 30 degrees to the left to bring the balance in the setup. Can't be true, I thougth and started to check the setup.
To my shame, I found that one of the loudspeakers was connected using the Linn K20 cable direct in the loudspeaker connection post - fixed by the B&W screw posts, and the other loudspeaker was having these:
So, I removed these evil plugs and connected the loudspeakercable the same way as the other loudspeaker. Tada! Balance instantly back. Still a small difference, but thats likely to be caused by the wall nearby the loudspeaker.
Never thought that cheap bananaplugs can make such a negative impact. I now need to consider to make some decent F-connections.
