I used a DONGLE for 100 days

iI did the same.
I use MuseHIFI M3 II and LOVE it

Bought Cayin RU7 to pair with my LCD-X. Love the analog sounding. The RU7 also makes my HD6XX sound incredible when doing a line out to Jotunheim 2.

I've used my first usb dac dongle LH Labs GO450 back in 2016, that drain my phone batt quite fast. It was good for laptop purpose. I'm not use any dongle, I'm sure the quality risen up this day

I bought Qudelix 5K based on Andrew's experience with it and have been very happy. Use mostly with IEMs or earbuds. It does drive my AKG K-361 well enough. Save my old school Samuels SR-71 Blackbird for really rocking out.

What do you think how does it compare to a Chord Mojo 2 or Hugo 2?

This video inspired me to buy the M15. It costs almost the same as my previously bought Fiio K7, and I gotta say that there is no way that anyone would reasonably say that M15 sounds better than the K7. I am getting much more clarity and airiness from the K7 with my headphones (Fiio FT3, HD6xx, DT990 Pro 250). So take this video with some reservations. M15 is usable as an IEM DAC, but for that money there are cheaper options...

Hi DMS! ❤
So Qustyle m15 is better than MuseHIFI M3 ??

I have a "modular" setup where each item fixes the shortcomings of another device. I have a DAC that feeds into a Headphone Amp and into a Monitor controller at the same time.

The DAC volume and source i control with my keyboard, like you, and if i wanna switch to speakers i unmute the monitor controller (which has a big nice attunation knob + xlr combo) and if i want to listen on headphones i have my dedicated headphone-amp to deliver enough power to anything (and also has a big analog knob). I also have a dedicated noise filter on the main line to never run into interferrence issues. Another piece to the puzzle.

This leaves me flexible in the DAC i choose. I can unplug my outputs from the dac and hook it up to a dongle, audio interface or a computer, etc.. and don't need to throw away a working DAC/AMP Combo device, just because it doesn't have this or that for a certain situation.

I did all that because i was never really satisfied with DAC/AMP hybrid products. They are either lacking inputs, or power, or USB support (no volume control, drivers), don't have a line out, the knob is digitally controlled, etc etc.. always something.

So i am all for little gadgets like that! Yes, i call it a gadget. To me a DAC isn't some magic device that needs to be super expensive. It is just a converter. Not the centerpiece. It is a single trick pony. I don't mean that in a negative way, but a DAC should focus on being a DAC instead of trying to be everything (and failing at it). In return opens the doors for more efficient designs and i hope more companies embrace it.

iFi really is onto something with their lineup, although the shape of their products is a bit odd but it basically is "modular". If you want bluetooth, buy the blue thing, if you want phono, buy that thing, and it all is the same form factor and has the necessary connectors to work together.

I think we need more "modular" products that don't try to be THE ONE and instead offer flexibility with good connectivity. That also means you are not limited to a single company (and hope they make a MK2 of your favorite, semi-perfect, hybrid one day).

Aiming to buy this as my first portable dongle. I do need to find some great IEMs. Hey can I just change any IEM 3.5s to a 4.4mm balanced cable?

As much as this is impressive, if I can only use it for my computer or phone, then it's of no use to me, as I need to be able to use it for routing audio out from my monitor and into a speaker, because currently the audio is too low going out from my monitor even at max volume set in both the monitor and the speakers.
Really hate that these kinds of dongles literally only ever have usb in, and not the option for 3.5mm Aux in.

Hi, is there anything that can boost the max volume on a bt/2.4ghz earbuds? Does a dac+amp helps wireless connectivity products to get louder/better audio? I found that the max volume on my earbuds are too low when its connected to my pc

Hello. Is it works with a USB-C to Lightning cable ? (ie : for Iphone other than Iphone 15). Thank you vey much.

Would love to see your take on the Fiio btr7

this vs cayin ru6?

I like this minimalist angle, if we listen to music mobile and at a desk, do we really need the 10% extra quality from a desktop dac when such a good mobile dac can do both ( i use moondrop dawn 4.4 to power my iems and studio monitors, it sound cleaner and more vibrant than my 3x more expensive ifi hip2 dac ). Not sure how much better sounding is that m15 at 4x the price of the dawn 4.4, is it a big step up from dawn 4.4 ?

Currently not shipping to the US. Do y’all have it in stock?

Im stuck between BTR7 and iFi Go Blue.. help?

Over lockdown I bought a E1DA 9038D 180mW 32Ohm 2.75V dongle DAC/AMP & a pair of Sundara's, haven't regretted it. Use it with a PC + Equalizer APO/Peace + Amazon MusicHD...

Anyone using the questyle m15 with the diana v2 and can share thoughts?

I currently have a DAP, walker h2, could I attach this to it? Can't see why not eh.

Need some advice please, if the ifi xdsd Gryphon and the Mojo2+Poly combo would cost nearly the same, which one would you choose? I would use it with Focal Clear‘s

Hi DMS! ❤

Hi DMS! ❤
So Qustyle m15 is better than SMSL M300SE ??

but years ago when i told people they didn’t need more than a few mw… you whipper snappers thought you knew what you were talking about 😂

I've been researching headphones to find the best model I can afford. I've encountered 2 problems that make me hesitate. 1) I listen to Classical music over high-quality loudspeakers, and by comparison, headphones don't seem lifelike. 2) It appears that equalization is almost universally recommended for headphones (I'm okay with that). However, I have thousands of CDs, and it's proving difficult to find the means to equalize headphones precisely when using a CD player as the source. The DSP hardware to accomplish that is rather scarce and rather expensive. I'm beginning to wonder if I should invest in headphones at all. Does anyone have suggestions/encouragement to help me move beyond my analysis paralysis? Thanks.

No mention about Moondrop's version that came out before this? How do they compare?

what watch is that?

100 days of being deaf

with that price, might as well add a little more and go for Ifi Gryphon or chord mojo2

Can we get a qudelix 5k formal review?

I love minimalistic and functional solutions

My Fiio BTR7 is my only dac or amp that I have and I love it. I have it on lanyard basically so I can wear it around the house and use my 560S or wired IEMs while I'm making my coffee. The 560 runs out of a phone but the A-B comparison between the two is night and day. Sounds fine in a vacuum but dead & strained compared to the BTR7. 120ohms definitely requires some power to achieve proper sound quality but still super cool it works with out.

Got the iBasso DC04 pro last week and been loving it. It works well with HD25, DT1990, HD6XX, DT770 and SR325. Incredible for the size of the device.

The major issue with dongles is the amount of power they are using from mobile devices such as phones. The more powerful a dongle is, the higher is the power consumption. Such tradeoffs are not suitable. I rather use use a battery powered dongles and have the best of both worlds

Why the fuck are my replies disappearing?

Noooooooooo you cut it off before he said 'Peace'! How could you!?!

For $249 you could get a Schiit Modius or Magni Multibit with decent real power supply and cleaning noise out of your USB. If you need headphone amplification you can go DX3 Pro or Zen Dac V2. Hopefully people realize that this is a special use case where portability and space are ultra-premium.

I have the Queststyle M15. Great little dongle, able to drive the V2 Diana’s and the Focal Radiance fairly well

E1DA 9038s/9038d made desktop Amps nervous some time before M15 ;)

It's a cool unit, but I would rather use my DAP (Fiio M11 Pro ESS) than my iPhone and a dongle.

I have a THX Onyx that powers my Hifiman Edition xs just fine

Erm....yes, I wrote this already back in June...of 2022. But, for iems with smaller current draw and an impedance not below 24 ohm, I still prefer the AudioQuest DragonFly Cobalt...also draws less current.

The Apogee Groove is the very best for headphones, but has a gigantic current drain and needs a computer source. Frequently sold in a bundle with the HD 600/650.

For iems, any higher priced desktop stack is overkill.

I tried Questyle M12 and it was not my cup of tea. I believe its sound is colored. Currently the dongle of my choice is NuPrime Hi-mDAC. If I need something better, I just take out my Chord Mojo 2 instead.

I have only one dac amp. Chord mojo 2. It replaced my big schiit asgard and bifrost stack. Saves me on electricity bill too lol.

is there enough power for my HD600?

Awesome dongle for laptop. Not so good for mobile because of power draw. But an amazing sound & power with minimal footprint. Highly recommend!

I’m currently using the Cayin RU7. It’s a 1 bit step ladder design. I’m enjoying the sound without a dac chip. But it doesn’t have the juice for 300ohm headphones.

i seriously doubt the dynamics and bass thump are quick on a dongle vs m15 for a headphone. this review is misleading. i guess its good for you if you don't need to listen to rock, edm, pop

Hey DMS. The m15 is my main dac/amp and I absolutely adore it, amazing piece of gear! Haha your review makes feel very justified about the purchase😀...Something to keep your eye out on is Questlye CMA18 which is their latest yet to be released portable dac/amp. I definitely will be!
