Input comes from USB2/SPDIF and it offers unbalanced RCA and balanced XLR outputs alongside the standard 1/4″ headphone jack.
I'm going to guess it is a headphone DAC/amp and will also serve as a DAC to feed a speaker amp or powered speakers.

The main problem is that once you pass the $200 point you get into real audio equipment. This is going to have to be either damn good or inexpensive to compete with existing dac/amp combos.

The XLR output is kind of a gimmick in my opinion. With the level of gear that is going to be used with something like this, there will be no audible difference between RCA and XLR. It is just a feature for Asus to slap on the box so people who don't know better will be enticed.

Oh ya, derp moment. You could just use the onboard optical out and this would convert to analog. No sound card needed.

No HDMI? I'll just stick to my graphics card if I want anything more than stereo sound.

It will complement it, it's an amp not a sound card.

For people who just use headphones primarily, a sound card wouldn't be necessary.

If your speakers accept XLR or RCA (more likely), a card wouldn't be needed at all.

The specs look pretty decent. I guess it really depends on the actual amps design, and how much they want.
I honestly think it will be a DAC/amp. STX/ST not needed. That being said, I am sure it will be $300 or so if they are willing to eliminate the need for their flagship sound cards.

I agree, I hope this is geared more to audiophiles than gamers.

whoa, better solution than the STX? I can still return my STX if this is...

Use the SPDIF on your motherboard to feed into this DAC.

It's both an amp and a sound card, the USB/SPDIF connectors confirm this. If you want an amp for your sound card buy one that is just an amp. A descent one will likely be cheaper than this.

It is a DAC/amp.

I am interested, along with others, how this will compare to a Maverick Tubemagic D1 which is considered a bargain at $200. I'm sure Asus will try to use their brand name to warrant a higher price.

Yep, definitely above $200... ST alone is $209 and STX is $199. I think anything above $350 would cause some to just pick up something like a e9/e7, nuforce icon, HeadRoom Micro Amp etc..

I wish the Peachtree Nova/iDecco/Decco were < $300. Those units are sexy...

This thing looks awesome. It does bit-perfect 192Khz. This is so my next DAC. I would project around $300 on release.

Here are some early working specs..
1. Hardware

Front IO:
Headphone out (1/4)
Headphone amp gain knob
Line out volume (independent to headphone volume)
LED indicators showing current playback sample rate
LED showing bit perfect (lights up when you’re kernel streaming)
Source select (USB/SPDIF)
Mute – it fades out instead of cut out the sound immediately, whichwill protect your gear, the same rules apply when you un-mute.
Power
Upsampling on/off
There is an estimated a 3% boost to SNR/THD when upsampling.

Back I/O:
Line out: RCA & XLR, unlike ST/STX, line out doesn’t share thesame DAC with headphone out. (XLR is balanced I/O and RCA is unbalanced)
S/PDIF in (both types)
USB in
AC in – a linear power adapter built inside to get the best power available

2. Software

A “invisible” driver, without it’s own UI and DSP settings. It gives you 192K and bit-perfect ASIO support it needs driver installation to work.

Circuit Details:
Input: USB2.0, S/Pdif
MAIN DAC: TI PCM1795
HeadAmp: NS LME49600TS -support up to 600ohm headphones.
Upsampling to 352.8Khz(44.1/88.2/176.4Khz) or 384Khz (48/96/192Khz), 32bit
Outputs: 1/4" headphone output
Unbalanced RCA line out
Balanced XLR Line out
