I have used the FiiO E10 USB DAC Headphone Amp for years now and have some general concerns about it's usage. Is it ok to use with the following gear?
1. M-AUDIO AV 40 Monitors connected via E10's line out
2. Sony MDR-V6 Headphones
3. Monoprice Premium Hi-Fi DJ Style Over-the-Ear Pro Headphones
The Sony and Monoprice headphones have a low impedance, so is it overkill to use the E10 with them?
Lastly, I'm planning to get a pair of Beyerdynamic DT-990-Pro-250 Ohm headphones. Is the FiiO E10 good enough to drive these?
Thanks in advance!
