Yes, and that is exactly what I expected to hear...  Better sound from USB than from the famous crappy Apple Toslink, but much to my suprise and chagrin, the Toslink sounded better, which was not what I was expecting.  The difference was not overt, but definite and repeatable.  I did this test months ago and repeated it many times over the course of a few weeks because I knew it was contrary to what popular opinion was.

For myself it really depends on the individual DAC's capabilities. My old Bel Canto just has toslink/coax inputs, and they sound the same no matter how I convert USB to coax (tried Bravo, V-link, and a simple straight converter). That is because it already has a good internal means of  asynchronously re-clocking the data and using an external spdif converter with its own asynchronous master clock provides no additional benefit. The only improvement I could hear is when I changed from a "high-quality polymer" toslink cable to a glass fiber one, that was definitely a step up and brought the optical up to the same audio quality as the coax input.

The weakest link to the spdif output on your computer is usually in the drivers.

Agreed.  I know you and I have at least one shared USB DAC experience to reference from.  USB DACs can sound great but the optical solution in my chain kicks things up a notch.  I honestly wasn't expecting the difference that I heard after hearing all the slams against optical.  There must be quite a wide range of optical implementations to have such a varied amount of impressions.  I have yet to hear glass cable and wonder if there would be a difference for better or worse.

Personally I have always preferred SPDIF, because I have really found all the drivers flaky for the USB implementations I've tried so far.  The only real stable one I have is the USB on the PS Audio DL III, but still prefer SPDIF.  I'm not using MAC though cause I'm just one of those uncool PC guys.  biggrin.gif

PC, Mac, or Linux, they all use a MAC address for network access protocols biggrin.gif

I would agree with you that on most DACs, toslink provides a cleaner and higher definition sound compared to USB audio output on a mac.

 

Nonetheless, with my previously acquired DI, I came with the conclusion that a good converter could make USB audio sounds better than the toslink output from a mac.

 

I have some confidence that the USB implementation on Bitfrost will be pretty decent so it will be interesting to see how does it fare between USB and optical input from a Mac =)

I have done some testing over a month of going back and forward and came to the conclusion that optical out of my mac was better than USB to hiface to coax. The hiface was nicer than straight USB and allowed me to get 24/192 but it still wasn't as nice as 24/96 optical out of my mac. I have high end coax, USB and glass toslink cables just to keep it even.

If I had never heard toslink then USB would have been at a level that I would have been really happy with. But then again... Being a headfier, we always. chase that last 5% improvement.

God I feel ashamed... I only just noticed the DAC is called Bifrost not Bitfrost. redface.gif

****, we were hoping you wouldn't figure it out!  =P

If you look s few posts up at least I wasn't the only one! ;)

 

One point that I don't think has been discussed yet by Jason is Linux. Yay or nay?

 

post #462 of 3320

Linux? We're not going to provide any technical support, but if your Linux machine is USB Audio 2.0 standard compliant, you should be in the same boat as Mac users--no drivers necessary.

That is what I expected but I wasn't sure. Thanks for clearing that up :)

Jason, what type of transformer is being used in the Bifrost?
