I have a Samsung TV and the headphone output is at a fixed volume. When I'm watching movies it isn't loud enough and I'd like to get a headphone amp to bump up the volume.I was considering the E6 but I don't know if it's powerful enough to drive two headphones. I would like to put a splitter into the amp to drive a pair of Logitech G430 and Sennheiser HD 558 which have an impedance of 32 ohm and 50 ohm respectively. Will the E6 have enough power to give me more volume in both sets or should I get the E11? I don't really care about EQ features and battery life since it will be plugged into the TV USB port at all times for power, I just need more volume. Thanks
