If anyone wants to try some iems with incredible synergy with the M15, I recommend getting one of the latest Tin HiFi P1 OG... they are now out of production but they can still be found on Aliexpress. They are legendary IEMs in terms of performance and for being among the first really well-made planar IEMs, but difficult to drive by almost all amplifiers, but the current amplification of the M15 will literally make them fly. You won't believe your ears.
The revision happened sometime around Q2-Q3 of 2022. The chances of getting an old one right now are pretty slim. Unless the store you're purchasing from has a year-old stock of them for some reason. Which is highly unlikely given how popular this dongle is.
I have a rather particular question to ask you... I own both the QP2R and the M15 but I can't understand which of the two has more powerful amplification and by how much compared to the other. Thank you.

Looking at pictures of my M15 (already sold), it was a v1.1 (received from Hifigo in May). Could it be that the v1.1 has slightly more background noise via the 4.4 mm output?
Zach here. I promise, Questyle hasn’t ghosted you (again)!
As you can tell from our channels, our newest product is RIGHT around the corner, no joke this time! Nooooo joke. So as you can imagine — been busy.
We also finally now have a full customer service team (!!!!!!!!!!!!!!!!!) Well, three of us for now, but I imagine it will be getting a lot larger very soon if you guys like what we have in store for you.
So now…. nope, you can no longer “thank Zach” blah blah blah. You can now thank Jenny, Jim, and that weirdo in the pink glasses.
All three of us will be managing these threads and others to better serve you, our loyal customers, because that’s frankly what you deserve.
Thanks as always for continuing to be Questyle fans!
Yeah, the first two sentences of that really paint a picture of their customer service. They were around for all of about a month on here. There’s a message on this board where Zach gives his email as a personal route to get help with the M15. I emailed him 3 different times after trying to reach Questyles non existent c/s and surprise, surprise - Ghost Town.
Disappointed to see this kind of negligence from Questyle. Non existent support nowadays. The download page has been broken for months yet they aren't fixing it. They've also stopped replying in forums.
Anyway, I have all the firmware versions from 9086 to 9399. If Anyone needs a specific one do shoot a pm.
Which amp did you use out of curiosity? I’m trying this now with a WHAMMY & ZMF VC. I’m quite impressed with this little guy as a smartphone DAC.
The power output is impressive, but with high impedance cans I’m noticing an audible benefit going to a discrete amp while using the M15 as a clean source.
