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.

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.

can the M-Audio FireWire 410 be used with a turntable (direct input from a turntable) for converting analog to digital? turntables need a pre-amp if not mistaken....

i'm trying to get set up to record some vinyl to cd. I was also hoping to be able to use the device for some home studio recording as well. if the M-Audio FireWire 410 isn't a good choice or i need a supplemental piece of hardware please advise. i'm pretty much a rookie here.

thanks

I am using Apple Airport wireless unit with its audio out connected to the benchmark media DAC1. I store all my music, lossless, on my notebook and stream it to the DAC1 through the apple unit.
