This is actually an interesting question, about a choice lots of us have to make: USB or FireWire on your DAC.

It doesn't really matter which interface you choose, as long as the implementation of the interface is good. Some DACs have only one, and obviously it had better be good if you're going to choose it. Some DACs (rare ones) may have both, but in this case both may not be equally good.

You have to either listen before you buy, or be prepared to resell if you're not happy.

The thing you do want to avoid is having both the DAC and external storage on the same bus. In my case that means a FireWire hard drive and a USB DAC. Some systems use double USB busses and put the drive on one and the DAC on the other. Some put the HD on USB and the DAC on Firewire.

I'm sure the original poster has made a decision by now but I wanted to echo the statement the poster above me made -- an excellent observation and advice about choosing NOT to have the external usb storage device and DAC on the same USB hub. I'll quote and link an article (Darko Audio article) below but it was from Gordon Rankin and goes into why and how USB as an audio interface has come a long way and why there can be a difference in sound with using different cables/computers/etc.

“For optimum results, at least in theory, it’s best not to use a USB hard drive for your library with a USB DAC connected to the same host device. Think of it this way: your music software is reading from the hard drive in a synchronous manner and then writing to the DAC in that same synchronous manner and, as the DAC has priority, the music software might fault when reading the disk – this can lead to really bad sound.”

~Gordon Rankin

Here is the link to the article for further in-depth reading:

https://darko.audio/2016/05/gordon-rank ... ty-varies/

While on the subject this was one bit of information from the same article that really opened my eyes too:

“Twelve years ago, I pretty much thought as many people do today: that USB was the answer to our S/PDIF quandaries. In some ways it is a good deal better. We have Asynchronous Isosynchronous so the device and host know about sample rates, bit rates, clocking options and a host of other things. But cables make a difference, computer brand and quality make a difference and even the device makes a difference.”

~Gordon Rankin from the same Darko Audio article linked above.


Hope this may help others in the future and best regards,
Jason
