External sound device vs PCI soundcard


Hi all

I’m still feeling my way around the area of PC audio, so please don’t shoot me if I’m way off track.

After reading through many of the post on this site is seems the general consensus is that doing a D-A conversion inside to PC case degrades sound quality to much due to electrical interference.

One way I thought of getting past this problem was to use an external sound device like the M-audio Sonic Theater, USB. If the sensitive DAC process was kept away from the PC, wouldn’t the output signal be relatively good.

Any thought or experience with external sound devices vs. internal soundcard would be greatly welcome.

Cheers.

I have juts aquired a USB driven M-Audio sound card, called MobilePre. I havent had time to test it thorougly yet, but my intention is to use it as a mobile test-setup with a laptop and a Behringer Microphone.

Anyone has some experience with this card used as a mobile testsystem like I intend to, or any other experiences with this soundcard?

If PC is located in another room, what's the max USB2.0 or Firewire cable's length possible? Ethernet is unlimited in terms of a house, but with the first two there may be a problem...
The optimum solution will be a high-quality DAC, such as a Benchmark with a USB interface installed, or an outboard USB-to-S/PDIF coax converter. Installing the USB interface inside the DAC is better, but the outboard converter can be quite excellent as well. Far better than the best transport on the market.

I picked up a Lynx One sound card (msrp $500) on ebay for $200, using Monkey Audio (APE) for lossless compresion, and foobar 2000 for my media player. It all sounds great but the sound card is designed for professional sound mixing people and sometimes I wonder if this makes the card a bit more difficult to work with. But it sounds great and I sold my MSB Dac/ McCormick Transport, have never looked back.

I tried an M Audio delta 44 but the computer power supply noise was so high I gave it up. I did buy and install their M Audio DIO 24/48 and have used their Flying Calf S/PDFI 24 bit dac for 4+ years with great results. I am doing many locations recordings in 2-channel and it sounds better than many commercial recording I buy. I do wish I had maybe bought the ADA 1000 from Lucid, but I am over it. It is probably better, but by what degree?

I have a new laptop and will be turning that into a 2-channel recording rig as well, probably using firewire. Cool Edit 2000 is no more so it looks like CakeWalk to the rescue.
