If your headphones could talk, upon seeing the Mojo, every one of them would ask "Is that a gumball machine in your pocket, or are you glad to see me?"
Since there exist since years excellent and pretty cheap dongles, I don't understood anymore neither the use case for DAPs nor bulky portable battery powered dacs/heaphone amps (what is the supposed source in this case?). Everybody has a smart phone, so get an almost SOTA dongle for $100 and you are done. Wht is the point?
Your DAP can only use streaming services when you have a wifi connection.Why would I want this rather than a DAP with a screen and android operating system?
It´s not a technical difficulty, it is how much it cost in processing power.Serious question, what is the technical difficulty in building such a sharp reconstruction filter?
As far as I can see none of these use cases couldn't be performed with a dongle and a smartphone or laptop.I think of it more as a small desktop DAC or a travel DAC rather than a mobile DAC. Some of my use cases include using it with a small laptop (MacBook Air), on my exercise bike, with a digital piano, and next to the couch for late-night movie listening. The optical/coax inputs are important for three of those cases (something lacking from most mobile DACs). In fact, I'm avoiding the USB input because a lot of people have experienced an issue where there's a sudden burst of full-volume white noise when using the USB input, and there's no firmware upgrade capability so there's no chance of it ever being fixed that way. There are various theories about what triggers the issue, including bad or loose USB cables and sudden changes in sample rate.
Yes, but a smartphone and a dongle?Your DAP can only use streaming services when you have a wifi connection.

Ok, and what would be the cost in comparison to these incorrect slow filters?It´s not a technical difficulty, it is how much it cost in processing power.
Nothing special with Chord's filters BTW

I don't mean to be too pedantic. But on the playback side on DACs you are looking at anti-imaging filters and imaging issues. If aliasing is in the recording you'll still get that.Better objective performance. Theoretically, no aliasing issues above Nyquist frequency. Soundwise, inaudible unless you're a bat that can hear the grass ultrasonic spikes with a slow roll-off filter
I understand that such a filter is more accurate, the question was what is roughly the additional cost?Better objective performance. Theoretically, no aliasing issues above Nyquist frequency.

Chord did in fact change the design somewhat from the original Mojo—for example, they added an additional globe/orb button—but it actually looks worse.The performance of this device looks great, but the industrial design is meh. It’s a shame Chord didn‘t update the design for this long overdue revision.

Oops. Have to live with that.Fine.
Sidenote: The FFT diagram says "Sabaj D5"
The only downside of the Mojo's (and is why I sold mine) is the battery crapping out after some time.
I hope Chord addressed that issue.
Almost the same price as a used RME ADI-2 DAC FS.
