First Steps into Computer Audio


Hi

I have shifted from traditional rig (first Vandy HT system w/ Arcam receiver, to Acoustat 2+2 with Belles 400 amp), to computer audio.

My main system is a desktop Dell Dimension P4 system, that has a SB Audigy 2 card. Will be listening to lots of classical, jazz, etc, as well as movies. Room is a very small 8 by 5 or 8 by 6 room

I just bought Audioengine A5's with the 25% off coupon, and likely will also buy some Quad 11L's to compare and sell the one I don't like as much.

So chain will be P4 w/ SB audigy 2 to A5 or Quad 11L (I assume the Quad 11L will be way better but will review and let folks know).

Now the question is what next to improve sound (and I will of course wait to do my next upgrade but already planning as most everyone says Audigy 2 is not very good.

I don't need a headphone amp (ok if it comes with) as 95% or more of listening will be done with speakers so I guess I could

1. Buy a better soundcard to output analog to speakers (say Chaintech low end, or 1212M higher end, or Xonar STX not sure my mobo is PCI E)

2. Use a USB dac from the usb ports, and feed speakers

3. Use the CB Audigy 2 digital out (SPDIF) to a DAC, or use the better sound card's digital out to the DAC to speakers.

I think would want very good SQ, but also keep price relatively reasonable.

Thoughts? Opinions welcome

The easier, less expensive way to go is getting a firewire to spdif converter. MAudio has the firewire solo for $200-you can get any dac you choose. Aside from streaming & packets, USB uses up CPU cycles, so a 480 usb throughput is actually slower than Firewire 400.

Drubin, it is an undisputed fact that the firewire interface is superior to usb by all computer techs. As I have said, just google it. I don't recall anything specific to dacs, just the interface. Please do a search and you will see what I mean. I am not knocking USB-most here are using it. All I am saying is that firewire, tech wise, is better.

Above are just two links I had from recent searches. I had spent a bit of time on this before I went with firewire. I understand most of the PC audio offerings out there are USB-and I'm not a Mac guy but, again, technology wise, Firewire is, well, better. I'm sure all your USB systems sound wonderful, and I have heard quite a few USB systems that sound great. I tried a few different USB set ups (utrends to spdif; benchmark dac w/usb) and, even with a pretty highpower PC, 10,000 rpm hard drives, I had some hiccups w/usb and sound stage was not as wide or deep, and have better resolution and retrieval of low level detail, and system is MUCH more transparent with the Firewire. Before you dismiss is, give it a try. I have tried both.

Cerrot,

Do the new asyncronous USB DACs like Wavelength and UltraFi overcome the USB issues you mention? I've heard the new UltraFi MusicStream DAC connected directly to a Mac Mini via USB and it was outstanding.

Enjoy,

I'm not sure, Reubent. My issues aren't with the DAC, just the architecture of the PC interface. I'm sure it sounds great. My only thought would be that using firewire out, the PC would perform better. If the PC performs better, I would think all would sound better as well.

Again, historically, USB was never intended to passthrough audio, just attach peripherals. I'm not sure why PC audio adopted USB as it did. I predict that within two years, all will be using firewire.
