I've never seen a pic of the inside of the mojo2
Edit, just googled it, quite ordinary looking, was expecting at least one capacitor? Something similar to Sony at least. Is it like a 50% resistor design or something? Of just completely different?

I'm no EE, but at a glance, I see quite a few of what look to be ceramic surface mount capacitors. But like I said, I'm no EE, so I could be wrong.

Looks very nice to me, especially that big square in the middle .

Would I be correct in assuming that because it has no capacitors it is also more resistant to heat?

It does have capacitors, lots of them! but if you mean a traditional electrolytic capacitor for supply smoothing, then I don't see one, unless it is on the under side (The PSU is).
If it does, it can not be a very large one, also Mojo2 does not get warm enough to damage any caps.

I think you might be confusing the fact that the Mojo 2 has no coupling capacitors in its output stage with having no capacitors at all. Because I see a bunch of what look to me to be capacitors in there.

I dunno why, like you, not an electronic expert. Only that Sony do away with dac chips and use capacitors (and make it well known in their marketing )so kinda thought there would be some in this instance. Like the one in the zx707 saying extra large one to Crete soundstage. But probably just marketing faff. And mojo2 isn't known for it's sound stage

You can’t replace a DAC with capacitors and expect to hear sound.

A capacitor simply stores electrical energy and releases it when called on to do so. It can be recharged very quickly and can dump the power very quickly so essentially acts as a backup to the battery in a power supply circuit.

Sony didn’t do away with a DAC chip, some digital to analog conversion is essential otherwise there is nothing for us humans to hear.

I have to say the sound from the Mojo 2 is pretty good with my AKG K701.
Never thought that from such small device the Quality of amplification could be so good.

It's deceiving, compared to huge desktop units to the outperforming mojo2. Makes you wonder what the hell are other brands are doing with these large units compared to the tiny mojo. I reckon if the mojo was simply larger with added weight, and the people would think it sounds even better again because of the bigger size.

Their latest generation of DAPs have gone the way of direct conversion at the output stage and doing away with a traditional chip. The new Marantz M1 does the same. It’s the same conceit as Wadia has done fir a very long time, like in the old 151 PowerDAC (which is still driving the TV system speakers at the ripe old age of 14 years old).

I loosely understood that the Sony has some sort of digital amplification that converts the digital signal to an output analog signal sort of in one operation or at least within one distinct part of the device rather than the traditional approach of separate DAC and amp stages.

I am not across the specifics but there still has to be a conversion from digital to analog somehow even if a traditional off the shelf chip approach isn't used.

I was trying to clarify that the use of capacitors wasn't an alternative to a DAC chip as the original comment seemed to infer, perhaps I misinterpreted the comment. Capacitors may be part of the power supply for the digital amplification and output process but they are not a replacement for a DAC.

No that's not what I said. Sorry if you read it so

All good, no problem created from my inference.

I see now where I misunderstood, I read an instead that wasn't there:

" .... I dunno why, like you, not an electronic expert. Only that Sony do away with dac chips and use capacitors INSTEAD (and make it well known in their marketing) ..... "

Can the Mojo 2 power ZMF headphones? The Atrium, in particular? I'm considering selling some gear and investing in more portable

Yes, I use M2 to drive my ZMF AC.

The same here. Mojo2 and AC is such a great synergy.

 

[Lyssky]

The same here. Mojo2 and AC is such a great synergy.

Mojo 2 is really successful with Caldera as well.
