I'm currently using a Nuforce udac-3 but I'm thinking of switching to something that can be used as both a desktop dac/amp and a portable amp. I've been reading about the Fiio e17k/e09k pairing and this sounds like something that might work well for my needs. I'm wondering if anyone out there has used these products (the udac-3 and the e17/e09 combo) and if you can give me a roundup of your thoughts. I'm using a pair of V-Moda m100s listening to a variety of music files, but only listening to EDM - mainly trance and house with some dub step thrown in. My portable device is a Samsung GS4 but I also have an iPod Touch....although I don't use it often. Are there any issues using the e17k with an android device with an OTG cable? Is aux my best bet? I've watched a lot of reviews on the e17k and e09k pairing, but I'm wondering what the head-fi'ers of the world think of this combo. Is the amp in the e09k better than the amp in the e17k, hence the pairing? I'm thinking of ordering the e17k first and deciding on the e09k later.
While we're at it - what other portable dac/amp devices would you recommend? Because I listen to EDM, I like to idea of having bass controls and the m100s can certainly handle the added boom. Most of my listening is done at a computer, but having the option of connecting my phone or iPod Touch is high on the list.
