Well after reading a ton of rave reviews re: the Mimby, I ordered one. My Mojo works fine, but I am getting a bit bored with the sound. I am certainly keeping it around for travel or for using my cans in a different part of the house away from the desk, especially the HD700s. Xbox One -> Optical -> Mojo -> HD700s are great for watching TV when trying not to wake anyone else up or playing one of about 20 hours of video games I play a year.
Really excited to see how the Mimby fairs, will definitely update this thread with my opinions once I receive it and let it warm up a bit. Will be feeding a Pro iCan via some Wireworld Luna 7 interconnects, and will be fed by a Wireworld Ultraviolet 7 USB cable and a Jitterbug coming out of the Sonnet Pro USB 3 card in my old Mac Pro. Headphones currently are HD700s with stock cable and LCD4s with the original blue stock cables, both balanced and SE.
Overall I've been wanting to sample an R2R DAC for a while, so I'm very much looking forward to this. As far as I can tell, should be exactly what I'm looking for sound-signature-wise. I've heard that in many cases, the sound of the Mimby is at least comparable to the Bimby, and in some, possibly even better. For $250, seems like a no-brainer.
@episiarch Thanks for the insight, appreciate it. Funny you say your Mojo battery is finally dying, I've had mine since April of last year, gets a lot of use, although much more in the last few months. Battery still seems to be fine but I've always worried about the day it would start losing its capacity. Given how hot it gets, I do have some mechanical sympathy for the battery itself. Not an ideal environment. But mine's been rock solid so far...just want to try something new and give this thing a break, keep it for portable usage.
