The M15 is well made, compact, and quite powerful. The sound quality is amazing. The small form factor allows me to listen to Hi-Res audio anywhere with just my phone and some headphones. This is also perfect for when I am working away from my office. I can just plug it into my laptop and I have another great HiFi setup without having to bring any other gear. Best dongle DAC I've ever used.
I have had a few of these dongle amp/dacs, the M-15 is the best so far! Clean power no noise and a fabulous Dac! The total solution for anyone who is an audiophile on a budget. For less than 300.00 you can not beat this ONE!
There is a delicacy and power to this dac/amp not found in others of the single variety. Powers my most challenging planar IEMs wonderfully.
Excellent device with the power to drive a surprising array of different headphones. Everything from IEMS, Hifiman XS, HD 660s, etc.
