Would it be possible to add in the ability to do the 2nd unfold for MQA like on the Dragonfly?

As this device is BT receiver first, USB dongle second, expensive (and questionable) implementation of MQA is not planned.

USB DAC - Yes
Dual pairing - Yes
NFC - No

You're starting to make me look like a fanboy. Stop it. No, don't stop. It hurts guuuud...

Optical output through the 3.5mm jack could make amps with optical input plug and play.

It would also make it probably bigger, heavier, much more complex and much more expensive.

 

[Nolbert0]

My understanding is that this is an m0 without the player...

I believe your planning to implement 'BT in -> USB out' and vice versa for the m0? Can we expect the same here?

Can it transmit as well as receive? If so, can it transmit in all the codecs it can receive? Iirc, aptx has some kind of limitation with this kind of thing, right?

Your understanding is wrong.

This is pure BT receiver/USB DAC, that is only using audio part of M0. So no transmitting, no digital out, etc.

Duly noted. These are just 'pie in the sky' ideas/questions. Learning tho.


Next question:
Is there going to be a 'hold' switch like the the walkmans of old? That jog dial looks really easy to accidentally press in the pocket or wherever u place it on your person. I assume it has a clip. I accidentally press it all the time on the M0 but that only activates the screen so it's not so bad. Since this thing (looks like it) doesn't have a screen, would a single press be play/pause? Do you see where I'm going with this? M2s, M3s and M5s have chunky 'leather' cases that lessens the dial protrusion to minimise accidental presses and I know somebody in the M0 thread designed a 3d printed case to address the exact same issue.

My observation is anytime you amplify analog input the sound is not as good as taking digital input. Therefore the UP2 must come with a really good amp stage if people are going to be happy with the sound performance. Or you can just add the digital output.

I found this to be small.

I would advise less tight jeans, so you don't press it by accident that often

Yes, single press will be play/pause, there is no hold button, but I was using it for some time and didn't had such problem.

This is BT receiver, in wast majority of cases used by people just wanting wireless sound from their smartphone going to their headphones, just small percentage of people will then use it as DAC with computer and their headphones.

So while digital out would be another check mark into feature list, it would be used by 1 person out of 100. Maybe. And in exchange for bigger and more expensive unit.

Also, it has no analog input, so not sure what do you mean?

 

[Ynot1]

Without digital out, there will only be analog output. So you would have to use analog input to amplify the headphone out. The analog input could be any amp that will offer different amplifying performance than UP2.

 

[Shanling]

As any other device on the market made to be used with headphones, UP2 has internal amplifier stage(only in this case actually combined with DAC stage in SoC Chip).

Considering there are almost no headphones on the market with digital input, I think we are fine.

And just to be clear, UP2 has only digital input, no analog input.

Actually, the accidental presses don't happen in jeans pockets... It never goes in there cos i got a clip! (for the m0) It's the looser pockets where it has room to move that it happens. Actually, mostly happens when clipped to jacket lapel or in coat side pocket. I mainly use the m0 as a receiver for my phone while walking the dog. My dog's not a vigorous puller and the accidental presses are still fairly common. If those accidental presses stopped the music every time, in stead of just activating the screen, might get quite annoying. Try your field test again with a dog walk as part of your routine and you'll soon change your tune. It's the crouching down that does it for me more often than not. I bet there's more than 1 in 100 that own a dog in your potential customer base.

Actually try putting it in a jacket side pocket and crouch down, shirt pocket and lean on a wall, and try other loose pockets where it can move around before dismissing what I say. A bluky jacket also makes accidental pressing much easier to do. I'm finding the winter easier to press the button by accident. A 3d printed case to 'guard' the dial for a bt receiver would be too ugly, not to mention overkill. This is actually a concern. Somebody even designed this to overcome this specific issue with m0. Your good selves has released chunky cases for M2s and above for similar effect so you know this design flaw exists...

Cases for players are for device protection, not to solve some design flaw.

We believe current design of UP2 (or any other of our players) do not cause any problems. Also, it's way to late to change anything.

I recommend to wait for some first users/reviewers and their feedback, after which you can decide.

I knew there had to be a reason you'd try to laugh off a genuine concern. Very legit reason to not revise designs, btw

Am I detecting a little deliberate corporate obtusity? I guess there has to be some... which I can also totally appreciate... (don't respond to that!)

Disagree. A good return policy is all i need! Or a review tour. Either or

Introducing Shanling UP2

New miniature Bluetooth DAC/AMP supporting LDAC, HWA LHDC, aptX HD, aptX Low Latency, aptX and AAC.

More information coming soon.

Love my M5s and Cant wait for this little gem. It'll be perfect with my Phone (which streams aptx HD) when cycling or in the gym.
