USB to DAC questions


Well, yes I have gone through many stages of what route I think I want to go for my new system... coming all the way from using a Zune for a player.

Now, from doing some reading on here, it sounds like the cheapest way (im on a super budget) to get great sound from my computer is to either go with a squeezebox or run USB to a USB-DAC. I was sold on the squeezebox... but it looks like I could pick up a used DAC for about the same price and have superior sound quality. Err, a DAC would beat a squeezebox in full a/d mode, right?

Alright, so I feel loaded with questions about a computer hookup that I didn't see any clear-cut answers to...

First, when we are talking about hooking up a USB-DAC with a USB cable... are we talking about just running the cable straight from one of the built-in motherboard USB ports... or are we talking about running it out of some additional hardware like a sound card with USB out. From what is sounded like, it was just one of the stock USB ports... but I need to make sure of this.

Second, most people here seem to favor MAC to output their USB signal from. Buying another computer would be WAY out of my budget. I am planning on running it from my workstation PC which is running XP because all my editing programs in Vista ran terribly. Yet, dual-booting to Vista just to have good audio would be ok as I already own a copy. So... just to be clear, there would be a big difference between XP and Vista when running USB out? It would be ideal to NOT have to dual-boot... but I will if there is that big of a difference. Also, has anyone been able to compare Vista sound with Mac sound?

Third, can someone elaborate on the difference between a NOS DAC and an over-sampling DAC?

Fourth, how would the Outlaw RR2150 receiver with a built-in USB DAC compare to a separate USB DAC paired with a separate amplifier?

And the last that I can think of for now... Does anyone have any opinions of the Musiland Md-10 DAC? I only ask because there is one listed on here in the classifieds at a price close to what I want to pay.

Whew, ya that was a loaded posting. I hope you guys can help me out with these questions. Thanks a ton.

Another Paradisea+ owner here. I do not have the USB version however. Currently just have it connected to the CD player via coax. Leaning towards the Trends UD-10 with the battery pack for connecting to the computer.

An Acer running Windows Vista. Vista improves on XP, and all older versions of Windows, by eliminating k-mixer which was what all the driver workarounds focussed on. Basically Vista is just XP without the extra hassle audio-wise. I've been using Vista since July without any complaints. If you can go Mac do it. I'd also go I2S, but the solutions here tend to be very expensive for what you get.

Some more expensive DACs including the USB Benchmark use I2S eliminating the need for an external connector. BTW the Paradisea is preferred to my $1k NuForce processor. I am using the Bendix tube and a tube damper rather than the cheap stock tube. It's also worth noting that the consensus view is that the Benchmark is very good but somewhat analytical, some people prefer the Lavry DA-10 or Monarchy NM-24. Also, you mentioned the SN DACs as well, just didn't make the cut for me, but the price is pretty good.
Djembeplay, yeah sounds like you're well on your way to a full blown outbreak of "the disease", lol. Anyway as mentioned you really do need to listen and figure out over time what it is that you like and go forward from there. Your proposed setup looks decent, choked a bit on the Monster cabling, but as long as you don't pay retail they aren't bad.

Also as mentioned the Trends UD-10 is primarily a USB converter that can be used as a DAC, but it will not compete with something costing at least 3x the price like the Paradisea. If you get a USB DAC you'd have no use for the UD-10.

Check out http://www.empiricalaudio.com/ for more on I2S and the linked 6 Moons review.

Basically I2S is an "electrical serial bus interface standard used for connecting digital audio devices together. The I2S bus separates clock and data signals, resulting in a very low jitter connection. Jitter can cause distortion in a digital-to-analog converter."
