Can anyone recommend a portable DAC/Amp combo that can power a Mr. Speakers AEON? My smartphone, the Pixel XL, doesn't anywhere near the power to drive the Aeon's loudly. I want something for my bedroom that can also be portable. My headroom Micro stack, while portable in theory, has never been used with batteries, and frankly I don't want to mess around unhooking it and lugging around those substantial bricks a lot, they live at my desk. I also want something with a low output impedance so that I can pair it with any HP/IEM without modifying their frequency response (my phone is 5 ohms output impedance, too high). Is the LH Labs Go2pro still something that the Best Audio Friends recommend for a portable DAC/Amp? I've read through the thread and am a bit confused about the availability of it and how sever the quality control/customer services isues have been. It seems like their products break a lot, but on the other hand it seems as if people like the ones that work right. Was also looking at the JDS labs C5D, but some of their products seems not too fondly thought of on here.
