24/192 is by design a digital signal, nothing analog about 24 bits

It accepts 24/192 max over the SPDIF- AES/EBU
The USB accepts 24/96 max. It is a bit dated design (adaptive mode) and of course it won't recognize DoP.

To play 24/192 you need a sound card with SPDIF out
If you send a signal > 96 kHz straight over the USB, it won't play.
Alternative, a USB to SPDIF converter supporting 24/192.
If you want to play DSD you need a media player converting it on the fly to PCM

Thanks! That sounds really good.
Would you give me a few store link to that USB to SPDIF converter or cable?
I don't know if it makes sense to buy two converters for this purpose. Is there any simple USB to SPDIF cable solution?
What do you use to play digitally stored 24bit 192 files theough DAC1?

There is a (incomplete) list of USB to SPDIF converters on my website http://thewelltemperedcomputer.com/HW/USB_SPDIF.htm
 
As many today DACs do have a USB input capable of 24/192 or even higher I wouldn't go the additional converter way.
 
I use Toslink most of the time. The standard says it is limited to 24/96 but in practice it plays higher

Do you think this will work?
also, if I use a cheap soundcard for spidif instead, will It decrease overall sound quality of DAC1?

M2Tech hiFace 2 makes the most sense to my budget.

Then, how do you use Toslink on PC to DAC1 setup?

Many thanks,

If I'm going to use something like this, it's like using two converters. Do yiu think there's going to be loss in sound quality in this setup? Is pure USB connection better?

My PC happens to have a Toslink out.
 
The "problem" with SPDIF is that the sample rate is generated by the sender.
If the sender has a cheap clock, this will generate tons of input jitter at the DAC.
I'm not familiar with all the products you listed but the Hiface2 does have an excellent reputation.

That's what I'm afraid of. If I'm using two converters at a time, their quality should match.

I found that my mobo has a toslink out as well. Can you play 24bit 192kHz FLAC files through toslink - dac1?

wait! I found that my computer has an SPDIF out !
In this case, can I just connect DAC1 with an SPDIF cable? and play 24bit 192kHz files? If this works, I don't have to worry about anything.

Maybe. It is far in excess of the standard but he hardware often performs better

Sure

 

[kawaivpc1]

Sure

Sweet. Now, problem's solved. Thanks!!

I can get full 24bit 192kHz from DAC1 easily by using SPDIF out of my motherboard!

Just thought i'd chime in as i just received my dac1. The th600 sounds superb out of the headphone jack. Dead black background. Running it via spdif to my studio monitors, also sounds superb. Excellent sound and value considering the price these can be had for right now.

I got an email from them announcing an updated DAC1 with 24/96 USB input:

They claim no special drivers (e.g. ASIO) are required for it. You pay dearly for the privilege of USB, though, an extra $300...

FOR IMMEDIATE RELEASE Benchmark Media Systems Announces First Native 96-kHz 24-bit "Advanced USB Audio" SYRACUSE, New York, February 15, 2007 - Benchmark Media Systems reinforces its position as a leading manufacturer of precision audio electronics with today's announcement of the DAC1 USB - a 192-kHz, 24-bit, digital-to-analog converter featuring "Advanced USB Audio", the world's first native USB audio solution that supports 96-kHz, 24-bit audio. Until now, special drivers were required for 24-bit word lengths and sample rates above 48-kHz. Benchmark's Advanced USB Audio provides high-resolution, bit-transparent playback just seconds after plugging into a computer's USB port for the first time. There is no software to install, and there are no system settings that need to be changed. Benchmark's Advanced USB Audio is compatible with Microsoft Windows Vista/XP/2000 and Mac OS X. "The ground-breaking performance and elegant simplicity of Benchmark's Advanced USB Audio technology is the ideal addition to the DAC1's jitter-immune UltraLock™ system", noted John Siau, Director of Engineering at Benchmark Media Systems. "We conducted stringent audio-quality tests on four different operating systems using a variety of audio playback applications. Our system delivers stunning performance without the compromises normally associated with computer-based audio playback." "The DAC1 USB is the only PC audio interface device that is fully satisfactory; in terms of bit-accuracy, sample-rate, and word-length performance", added Allen Burdick, President of Benchmark Media Systems. "It's intuitive, it's easy - it's USB audio done right." The new DAC1 USB, which begins shipping worldwide on March 1, 2007 at a price of $1275 USD, also includes high-current output drivers that can be configured to mute upon headphone insertion. The classic DAC1, which does not include the USB option and special high-current drivers, is still available for $975 USD. Both options are available in the silver, black, and, black rack-mountable chassis. Benchmark's DAC1 - a 2-Channel 192-kHz 24-bit digital-to-analog converter - is the recipient of a multitude of awards and a consistent top-seller in both the pro-audio and audiophile markets worldwide. "The DAC1 set the mark for digital audio conversion - uncompromised sonic integrity at an incredible value - the DAC1 USB does the same for PC audio", emphasized Allen Burdick. "The importance of high-resolution, bit-transparent computer audio playback simply cannot be overstated. Computer-based audio is used almost exclusively in the broadcast world, it's commonplace in recording studios, and it's revolutionizing home audio systems."

Does anyone know if this will work with iPhone?
