I am not big on the bling factor of audio gear but I think at that price you may want to consider a nicer face plate and buttons.  You will sell more of them.  It would also be nice if you could order one with XLR's.  My system is fully balanced, including my Luxman DAC which I would eventually like to replace with something more SOTA.  MY system just sounds better fully balanced.

The faceplate is machined 8mm aircraft aluminum, anodized.  Costs me more than $100 each.  You want me to spend $200 or more for a faceplate?  This would add about $500 to the cost.  Most companies use 4-6X multiplier.

If you want fully balanced, my Overdrive SX is hard to beat.  Only a couple of DACs compete with it.

I am not complaining about the face plate but I know a lot of people take into account of how gear looks.  McIntosh sells a lot of gear just on looks alone. :D

I don't want it to be ugly, but my products are all about sound quality first.  I'm not about audio jewelry.

The pushbuttons are heavy-duty for extended use and low resistance for the AC power.  Unlike many DACs, there is no power usage until it is turned-on.  The regulators don't waste much power either, even though there are 11 of them.  Runs much cooler than my Overdrive SX.  Much Greener.  Also, the power button is on the front panel rather than on the back like many DACs.  My cost on the pushbuttons is $14 compared to $2 for other manufacturers.  The standard buttons are plastic, but there are aluminum ones that no one stocks.

Too late.  :P   j/k

Screams 70s style! Having grown up in the 70s, I love the red and gray buttons and Mattel-ish industrial-chic style. I was a little shocked when I first saw it, but it quickly grew on me and now I think it looks pretty cool. Maybe millennials are finally ready for some 70s vintage look; they sure like their vintage 60s and 80s styles.

So the SPDIF with SynchroMesh is intended to be the primary/best input in your view?

XMOS usb?

Is this internal synchromesh implementation just as effective as the external Synchromesh product?  I have Sonos with terrible jitter, I'd like to be able to use that for main transport without an additional jitter removing device between Sonos and DAC, like all my previous DACs.

Does the synchromesh filter affect the data stream coming from USB and ethernet inputs?
Thanks

Both inputs are equivalent.

Yes.

Should be even better because there is no S/PDIF conversion or cable involved.  Just I2S output.

Should do the trick.

No, these are bit-perfect and low jitter. Not routed through the SM like the S/PDIF is.

SPDIF and USB only .... no Ethernet as per first post in this thread?

(USB*S/PDIF) + (Ethernet*S/PDIF)

Earlier in this thread some opinions were expressed to the effect that Empirical Audio's styling is lacking. I was too busy at the time to comment, now with a lazy holiday afternoon and this thread popping up here are my opinions.

I have always appreciated the clean minimalist form follows function look of Empirical Audio's products. I would even argue given their name minimalist is the logical choice. Among industrial design professionals and educators the contribution of Dieter Rams to the field is quite literally the stuff of legends. So when I say Empirical Audio's styling reminds me of Rams iconic designs for Braun that is one of the highest compliments I have in the area of product design.

It is accepted that Apple looked to Rams for many of its designs.

I've had some feedback from a good customer and I decided to redesign the front panel per his advice.  It looks more elegant now and less bold.  I like it.  When I get the new proto panels, I will post pictures here.

On another thread I was criticized for using shipping companies and selling an unnecessary product because these create CO2 and therefore unnecessarily add to Global Warming.  I responded by saying that humans need culture to thrive and my products are small and light, so they share the shipping with a LOT of other cargo, making their footprint small.  In the future, my products will create even smaller carbon footprint as the power system transitions to renewables and transportation converts to electric.  I personally have already made this transition.

In addition, this new DAC consumes significantly less power than my Overdrive SX DAC.  This is by design.  I want it to be as green as possible and create the smallest carbon footprint.  This is the responsible thing to do.
