Psag,
Yes, the Beringer allows independent level and EQ of each channel, and it really does help my situation considerably. I also found that if, for example, you need 3dB of boost for the left ear, you should decrease the right channel by 1.5dB and increase the left channel by 1.5dB. This way, your good ear (in my case, right) is not hearing a 3dB boost in left channel information. I have 4 saved settings to accommodate a 1.5dB, 2dB, 2.5dB, and 3dB balance shift. I find that vocal recordings or anything with a clear center image requires 3dB, while I can get away with one of the other settings for orchestral or jazz. I find that even a slight change can make all the difference between enjoying listening and saying to hell with it. You can get the Beringers for a good price ($225-$250 used or a little more new), and they are very effective and completely transparent in my system.
