Hi, I recently purchased a DT 880 Premium 250ohm headphones and I'm loving it. I also got an Fiio E17 with these pair of headphones and even with gain set to 6, the volume from 30-40 is loud enough for my ears. Will I benefit at all from purchasing an E09k if the E17 is loud enough? Other than volume will the E09k benefit in anything else? Also what is the best settings to set my E17 at (gain 0 and higher volume? Gain 12 with low volume? Or should I keep it at gain 6)
Thanks so much for your help!
