First post here.
Been reading through forums and really enjoying my trip into audiophiles world.
Recently got my hands on Fiio e17. My headset EKG 271 mk2 is not the most demanding headset amp wise, but I still wanted to evaluate e17 without any bias. but So first thing I did was - blind tests! Well kinda.. home made.
My testing setup was:
- laptop+foobar2000+wasapi --> usb --> e17 --> EKG K271 mk2 (55 ohms)
- Samsung galaxy s3 ---> EKG K271 mk2 (55 ohms)
All equalisers where nulified, 0 gain on e17, volume controls maxed out on my laptop. Sound levels where levelled using my dear ears. Material: Alice in Chains MTV unplugged, some classics, some Daft Punk stuff .. all same flacs 16bit/44khz.
I had same songs running and my wife swaping the cabling behind me.
Results? Samsung s3 won hands down. Altough I was 100 % convinced of the opposite result beforehand. Surely dedicated dac/amp would win? Not really..
We then changed places with my wife - again, she chose s3 over usb/e17 combo. We both agreed that e17 sounded a bit muffled (?), like under the pillow, compared to s3.
Anyone can shed some light on it? I REALLY believed I "need" external dac/amp - now I am not so sure.
And yes, these headphones are not 200 ohms.. but I would still expect e17 being dedicated device beat mobile phone in Digital_to_Analog conversion?
Or is it just my hearing? equipment? flawed testing?
