Teething troubles with 120

[yabaVR]

...Odd instruments would sound fine, but an issue with voices. Hmmm...

That's the point. The devialet does not distinguish between voices and instruments...it's just a dumb amp   (no, no... not you my lovely D   )

I can only imagine:

- something out of phase, for sure not inside the Devialet, but you can check that they put in the binding post the right way. Looking from behind, left to right, it has to be (+) (-) (+) (-)
- if you got two different speakers it's very unlikely they are both fabricated out of phase inside
- speaker cables can be marked the wrong way (+) (-), but again if you used the same cable with the other amp and had no issues 
- if you didn't touch anything in the configurator there is nothing changing the phase and if you did, you can only change the absolute phase (180°) for both channels at the same time (but I bet you won't here any difference of that kind)


- to my interpretation, if the effect is that big as you discribe, it has to be a significant reduction in the frequency area of human voices. If you are certain on this I would meassure the effect. Get yourself a db-meter and a sweeping sine tone on CD and test if there is a significant reduction at any frequency at the position of your listening chair.

- to be sure it's not your D120 you have to get another Dxxx to compare it to. Any model would be sufficient. Perhaps the best and easiest way to figure out what's wrong?

Any other way it's difficult for us to discover what's going on if we can not hear it ourselfs...
