Looks good but I’m going to hold a bit til next week when the new one comes out and see if the D400 Pro Mk2 is better.

LOL, SMSL topping churning out products at crazy pace, I just saw the ad for smsl vmv d2r last week selling for about the same as a d400ex, using rohm chips.

Yeah their line up is confusing since too many different products. Hard to differentiate which product is aiming at who and what.

Also doesn't help that if all their dac measure super well, do they all sound the same? And if it sound the same do we need to buy another one?

It's a very confusing matter.....

I was reading up on this DAC and there is not a lot of literature so that was finished rather quickly. I am a bit confused by this statement that appears on a few sites and I hope that someone can help me: "Dual mono design, one AK4499EX per channel". Does this imply there are two ak4499ex chips? In the youtube clip there is a snapshot of the board that shows only one ak4499ex....so is it a mono DAC?

Will there be a headphone amp in the same design so you can create a stack?

The 4499EX is a new design which basically makes a separation of digital and analog circuitry, AK4191 for digital and AK4499EX for analogue

Thank you for trying to clear up my confusion, but I'm still not smart enough to understand the how the statement "one AK4499EX per channel" translates to using one chip for both channels. I believe you are trying to convey the digital/analog processing duty separation but I'm stuck in the literature of how the left and right channels are converted from digital to analog. Appreciate the reply.

 

[nick2x]

I noticed the statement forementioned has been removed from the DAC specifications so it might have been just a specification fluke. Confusion /end

 

[Jimi Zine]

Yep I think it's the two chips together as one (digital then analogue) for both left and right

 

[gattari]

Very nce look, i want one.

 

[pataburd]

Bigger and heavier than the [2x 4499EX] D400EX.
Any comparisons with the M400 anywhere?

 

[mars chan]

This is the best looking smsl under 1K I have seen , I only wish it has the display of the topping d70 pro.

 

[pataburd]

I'd be interested in an M400 and/or D400EX v. D400 Pro comparison.
Deo volente, I should have the D400EX on hand by Thursday to a/b the M400 v. D400EX.

 

[pataburd]

Cannot use the HDMI connection between NuPrime CDT-8 Pro and SMSL M400.
The frustrating part is that the pin-out configurations all match up except for the last three (pins 17, (18) and 19)--actually just pins 17 and 19:

For the CDT-8: GND, (NC), NC
For the M400: NC, (NC), GND

WHY???

All I have on hand is a [Pangea Audio] Toslink: decent but limited to 192kHz.
