Your comments about the ES100 are moving me to that device. I'm looking to free up my smartphone from an attached dac/amp, but still have higher output from balanced and limited battery power drain from my smartphone. I was looking at the E1DA that's being recd on the Discovery thread (and while it really looks like a giant killer in terms of power, specs and resolution) I don't like how much power this will draw on my smartphone's battery, and the fact that I will still have to buy a decent sized power bank to keep my phone charged, while using the E1DA. Altogether, the E1DA system seems more complex than my Q1MK2 hooked up to my smartphone via a short OTG USB-C to USB mini connection cable, and a few strips of 3M Dual Lock to attach the dac/amp to my smartphone. I'm starting to think that the Earsonics ES100 is a better option now. My goal is to reduce the weight and complexity of my current setup, and allow me more functionality with my smartphone, while still retaining high SQ. I'm gonna pull the plug on the ES100 tomorrow. It's $129 on Amazon.ca and includes fast 2 day shipping, cause I'm a Prime member. Thanks,
@Slater! Looking forward to getting this device.
