USB DAC options

**RedGTiVR6** · 09-17-2006, 08:33 AM

Hey all.

Seeing as how the USB DAC has become a popular option for some folks, I figured a thread listing the options out there would be beneficial.

I'd like to set it up much like the 5.1 amps with digital ins thread, and the mini-itx threads on this board elsewhere.

So show me what you have found!

Seeing as how I'm sure there will be much debate and discussion regarding these DACs, I figured a few words about them from various sources might be beneficial to some.

What is a DAC?

From the Stereophile Forums talking about jitter and USB DACs as well as USB two way communications for error correction. VERY good read.

well i guess i'll start.

this is the one i'm currently testing:

we'll call it the 'douglas' hpdac. since this is a diy board you can use whichever components you'd like. I'm currently running burr-brown opamps and blackgate caps.

also... since it's a diy board you can wire it with female rca's to connect directly to your amp. This will give you a digital signal within inches (or less) of your x-over or amp. If you are going the x-over route you can also think about cracking that active x-over open and wiring the outputs of the dac directly to the inputs of the x-over.

I use the Silverstone USB DAC. It of course doesn't require a driver, just plug it in and it shows up as USB Speakers. You don't have to worry about turn on thump w/ most DAC's, as w/ the SS it doesnt turn on till it gets music to play. The DAC doesn't require in extra power... just a single USB cable will do comms and power. The sound is rich and clean.

The problem most DACs (that have problems) have is that of IRQ's. On my setup I have 8 USB 2.0 powers onboard and a add on card, along w/ the normal basic interupts. When I first connected the DAC to this setup I had cracking and popping... after disabling a couple things in the bios I've lost all but a slight crackling every now and then. The fix is usually changing the PCI latency or changing IRQ's for the device.

You can change the volume of the DAC using your front end, correct?

Correct!

*clutches chest and reaches for phone to dial 911* j/k. Amazingly resembles the prices my brother charges for the high current tube amps that he builds.

*edit*
Would the average person/carpc system be able to discern the quality difference between an $84 Silverstone and a $195 HPDAC? I don't even want to try and get my head wrapped around the Cosecant, Brick, or Ultimate DPU.

The average person can't tell the difference between a MP3 ripped a 128 and the true CD source.

However, it's like anything else in life. If it's something you are into, which we all have something, you know the differences.

When you live and breathe something nearly every waking moment of your life, you can tell a difference.

If that was the truth it would be a shame.

why do you think the iPod has become so popular? Why do you think there are companies making millions off of selling mp3s that are much less than CD quality?

it's because people don't know the difference and don't care to.

Try and find a music store online, where you can download music files in HIGH quality.

There was 1 that I was aware of, and even then, it wasn't 'HIGH' quality by many standards...
