Interesting Solution to Stream USB to S/PDIF

Posted by: Skip on 24 April 2010

I have been a big fan of the Devilsound DAC 2.0 cable, and have been on their email list for a couple of years. I thought their new product to allow USB steaming to S/PDIF would be of particular interest to this group, since the Naim DAC won't stream USB.

I recently consigned the original Devilsound DAC to headphone use with a Ray Samuels amp and an RCA to mini adapter, and upgraded my main system to the newest cryo-ed Devilsound 2.1 DAC. At about the size of a slimline Zippo lighter in the middle of a USB cable with a pair of RCA pigtails into my preamp, the Devilsound DAC is a great product for somebody like me who has a great turntable and CD player already, but no room for a full sized DAC, and the new version is smoother with better resolution, and quite the upgrade from their original DAC.

Now the Devilsound folks have come out with another cable under the brand name "Halide" to stream USB to S/PDIF. It runs Streamlength USB receiver code under license from Wavelength Audio, who pioneered the asynchronous USB DAC, so it's 24-bit and 96-kHz, and the output clock is locked to the clock on the Bridge itself for lower jitter.

Since you need a big boy DAC to use one, I have not tried it myself. I did hear Kent's Empirical Off Ramp when we did our Naim DAC audition here vs. the CDS2 (now with 555PS!), and I have seen the HiFace writeups on this forum. The Empirical sounds very good, but it requires space on the shelf for the electronics and additional interconnect cables, as well as a wall wart power supply. The Halide Bridge has all that stuff in the cable itself, and costs about half as much as a result.

When I get my Naim DAC, so pleased have I been with the Devilsound DACs, I intend to make this single cable solution my first call. 60 day money back, just like the Devilsound DAC. Then we can get another shootout together!

For those of you who have tried both, do you believe the BNC or RCA inputs sound better on the Naim DAC? The Halide Bridge comes to order either way. For those of you who have a better understanding of the limits of the Naim DAC, can you see anything in the attached which would keep it from working the the Naim DAC?

Check it out. It looks like a great solution to me. I have not tried the product and will not until I step up to the Naim DAC, but I am pretty sure this is an effort worthy of your attention if you own a Naim DAC of your own.

Good find - especially as its using Gordon Rankins code expertise.

This asyncronous USB to S/PDIF converter looks very, very intersting to me and should be among the best solutions to connect a PC or MAC to the Naim DAC and it is rather cheap for what it is offering. What I do like is that this device gets plugged right into the BNC input of the DAC: No further cable needed! This should turn any PC or MAC into a serious music server.

Looks good, but you can only buy on line using PayPal - so that rules it out for me.

I bet they would find a way to work with a Naim thought leader if you made contact with them. Winker

Looks good, is this any different to a Hiface or belcantos Usb link?

Looks as though it will only play 24/96.

"Streamlength is completely plug-and-play. For a single cable design, not having to deal with installing drivers is critical. Streamlength also automatically allows the user to select the output frequency of the device - 44.1, 48, 88.2, or 96 kHz (Note: 88.2 may not be supported under Windows Vista/7). This allows audio to be run at the native sampling rate, or can be used to add an additional level of oversampling. (For instance, selecting 88.2 kHz when playing an audio CD will give 2x oversampling, before the signal even reaches the DAC.)"

Looks like it will do all up to 96k but no auto native switching which could be an issue for many. I suspect most will plug and choose 96k to avoid the hassle of format switching but for me this wouldn't be desirable as I much prefer to output native. Looks neat but not for me.

Wonder what the cable length is? I've E-mailed them for this info.
