AKG Q701 Headphone Dac/Amp
I've recently bought a pair of AKG Q701 headphones to use with my ipod and iMac computer. I realised they would need a headphone amp so I bought a Fiio E7, this gave a fair sound but was still lacking in the volume department. I added a Fiio E9 to use with the E7 via USB from the iMac and the sound is very thin and overly bright and still doesn't seem to have enough power to drive the AKGs.
I'm wondering if I need a better headphone Dac/Amp I could spend up tp £250 on one to use with the iMac . I want a powerful amp to drive them properly, am I expecting too much from using the iMac as a source, are the AKGs too revealing ?
