Yeah, I'm hoping a couple others who've tried some of the other DACs could chime in with their experiences.
Anyway, if I could summarize my setup in two lines, it'd be as follows:
• Devices: HTC One, Samsung Galaxy Tab 2 7.0, MacBook Pro, Toshiba Satellite (i.e., a healthy mix between these four)
• Cans: MDR-V6, Fidelio X1, ATH-M50, some cheaper on-ears and IEMs; currently looking at the ATH-Pro500mk2 (38Ω, a little warmer than the M50)
Edit:
OK, I've narrowed it down to one of these four options:
• E07K ($89)
• E11+Muse mini USB DAC ($98)
• E18 ($160)
• E12+Muse mini USB DAC ($167)
I'm so close! Guess I might just have to do some old-school buying-and-returning from Amazon to experiment and see which option works best for me.
Edit 2:
I just purchased the E12, E18, and Muse DAC. I'll compare the E12+Muse vs E18 and hopefully return the lesser of the two. Hopefully this doesn't backfire...
