Hey everyone,
First time poster here, but definitely have been reading for a while.
I had a peculiar question.
My MF V-CAN, when used at low volumes, only outputs to the right ear of my Senn HD600s. But once I start to turn it up, the left ear piece starts to produce sound. From what I can see, at higher volumes they both are the same volume. 
 
I'm just confused why at low volumes it does this. I tried plugging it in to other amps and direct to my laptop and it seems fine. 
 
Thanks for the help,
Chris

What you are describing happens with almost all analog volume POT (potentiometer); there is always some kind of channel imbalance.  It just depends on the degree of it.  To get perfect channel balance you will need to get an amp with a stepped volume POT, like the one used on the Burson HA-160/HA-160D, or the Meier-Audio Concerto.  On my Luxman P-200 headphone amp, the channel balances at about the 7'oclock position and above (using the Beyerdynamic DT990 600ohm headphones).  I don't know they technical details on why this happens.

That makes sense thanks
 
Would be a good idea to grab a better potentiometer and put it in? I'm assuming this isn't that big of a deal since it must happen to a lot of cheaper amps. The music still sounds good. I'm just being curious.
