USB DAC or USB to SPDIF conv. + non USB DAC?


The only digital out from my PC is USB. It is my understanding that a USB connection will limit the sample to 44.1 or 48Hz (correct?) So, Im thinking of getting a USB to SPDIF converter (like the HagUsb) plus a non-USB DAC (like the Lite NOS AH DAC).

Does this make sense?

The digital output from any Soundblaster card is abysmal. Asynchronous USB is fast becoming the new standard.
Thanks for all the replies.

I wound up getting the Giga Lab USB Moon DAC from Pacific Valve for $210 including shipping. This is an NOS DAC and it does impart a sound slightly like tubes. It also has coax and toslink inputs. No headphone stuff. Well worth the price.

I also discovered that my Soundblaster Live! 5.1 card does have a digital out: its a 3.5mm into which I can plug a mini > optical toslink adaptor(under $2 at Parts Express). Haven't tried it yet.
I've been thinking about the Peter Daniel option as well. For all of my hand wringing, please see this thread:

Music prof - I also have the Nixon UFO.JF and the Chibis on my short list.
Have you checked out the $380 hand built $380 Peter Daniel USB (Audio Sector website)?

Also on my short list: from Pacific Valve & Electric: Musiland MS10 ($300); Giga Lab Moon ($185) and Diyeden SVDAC06 ($169).

Restock & Sammie -
I am shopping for a new PC - probably w/ Vista Home Premium.Some of the ones I've read about (out of my price range) have sound cards that are 24/192 capable. Apparently, this is for DVD support as they are all 5.1 or 7.1 w/ multi channel analog, coax digital, Firewire and HDMI outs.

You might also consider one of the Scott Nixon USB DACs. I hear that they are excellent. I am trying to decide between the Cambridge Audio DacMagic and the Scott Nixon USB.UFO.JF. For information, please see:

I am going to make a final decision in the week or so.
Hey, Restock - any idea why/how the Benchmark and the Cosecant can do 24/96 via USB while the less expensive USB DACs can't?

Actually the EMU0404USB soundcard can do 24/96 for a around $230.

Otherwise, it depends on the USB-SPDIF conversion chip most DACs use for their USB input. Furthermore, some DACs are non-oversampling and plain limited to 44.1 or 48KHz sampling rates (e.g. Wavelength Brick and MHDT DACs).
Yep, you're right, the Brick cannot yet be ordered 24/96, although I'm sure that is in the works.
I don`t the Brick can be order with 24/96, but its a great sounding dac as is.

I can not think of any better choice than MHDT Paradisea Plus USB Dac for your budget.
Just to add to Restock's post.....all Wavelength DAC's can be ordered with 24/96 capability. Yet, as far as I know, that is as high as USB will go for now anyway.

Yet, with a good soundcard or through firewire, sample rates can go as high as 24/192. And, there's downloadable music available at the highest sampling rates.

Thank you all for your responses.

Unfortunately, I cannot afford a Tranporter or anything from Benchmark or Wavelenght: My budget is $500. Even a used Brick ususally goes for more than $500.

Will probably go with a USB DAC. Maybe the new Cambridge DacMagic ($450 @ Audio Advisor).

Incorrect. Both the Benchmark DAC1USB and the Wavelength Cosecant (Numerator) will allow 24/96 rates via USB.
You could also go wireless, such as to a Squeezebox, and then use its S/PDIF digital out. Another option is to connect peer-to-peer with the Squeezebox via Ethernet. In my experience, this Squeezebox solution is sonically superior to inexpensive USB converters or USB DACs. You will be limited to 16/44 unless you want to step up to the Slim Devices Transporter, which gets you to 24/96.
If your PC is a desktop, you can always buy a sound card with SPDIF output. This along with the proper OS will allow you to have more options.
You will still be limited to USB's output that way, so I would stick with a good USB DAC.
