Tried combo with a Windows Vista 32 Bit PC and the Left channel still isn't working properly. Looks like I'm returning the E9 to Amazon.   Pity as It's an excellent Amp otherwise 

Just tried connecting the the E7+E9 to a Laptop running Windows 7 64 Bit and I can hear the Left Stereo channel but  it's very, very faint. I've checked the balance for both channels and they  where balanced for both channels. Tried playing with the balance to both speakers and the Right...

When the E7 is docked with the E9 and it's connected via USB  I just get the right stereo channel. If I connect the E7 via USB  or if I connect the E&+E9 via line in  to my PC it works perfectly.    Had the E7 for a couple of months and the E9 was delivered yesterday and I'm very impressed...

Hi, I've got the same problem with Windows 7 Home Premium 64 Bit, but I'm only getting sound from the Right channel. Would be nice if somebody has a solution
