Great review.

Man I so want to try this one out!!

@gadgetgod Mate, it's really an end game ultra portable dac-amp imo. give a PM to Questyle, who know...you deserve to review this lil'marvel!

@NymPHONOmaniac i will PM Questyle Thanks a ton mate <3

Would be nice to compliment my RU6 when my Qudelix 5k battery stops keeping a full charge, but that day has yet to come!

Interested in a Gryphon comparison (SQ). I'm sure there's fans of xbass and space. The portable market is insanely good right now.

@OhmsClaw indeed, dongle market is hypertrophy right now....their a new dongle every week, yet, those that are exceptional like the M15 are rare. 5K is quite neutral but have leaner dynamic, dryer timbre from what i remember. still an excellent BT dac-amp, perhaps the best. Gryphon is certainly more powerfull than M15, but can't comment since i haven't test it. but one thing sure, not only reviewers love it, consumers too.

Thanks for your review. Wanted to buy the M15. But it seems not to pair well with earphones/headphones like my Dan Clark Aeon Noire (13 Ohm/92dB/V) or Meze Rai Penta (20 Ohm/100 dB/V)
Any experiences with these combinations?

@klaus2325 To be completely honest with you, we haven't tested the M15 in house with either of those headphones, as we don't have them in our lab... so I'm really hoping that someone can answer your question from first-hand experience.

At the same time, perhaps this could be helpful: could you share what leads you to think they wouldn't be a good fit? Perhaps I could get one of the engineers to respond directly to that concern, if that's helpful to you.
