Default I2S from a PC, Firewire or ethernet?

I would like a means of getting 24/192khz out of my PC. USB seems flawed, Firewire rectifies most of these problems, ethernet seems ideal. I have searched and searched for a cheap solution. I had heard of someone running their DAC from etherneet and cannot find the details. Can anyone guide me to a DIY design or commercially available product to get I2S fro a PC?

- squeezebox
- 192k ? where?
- usb flawed? huh?
- FW rectifies uhh?

how about some real issues, like latency, instead of creating some, like 192k...
If you dont like latency, get a firewire soundcard, the new ones.
- you know how to handle i2s?



"I would say that there are almost no documented cases where a properly dithered 16 bit 44.1 kHz file was audibly distinguishable from its higher bit resolution or sample rate source file."

Thanks for the help. It is days like these when I wonder if I should even ask for help.

-Where? 192khz from my PC high rez files, most are 24/96.
-USB flawed, yep, flawed. If you do not see the limitations of USB vs Firewire for example or that the word "rectifies" can be used outside of power supplies, why are you mocking me?
-Yes I know how to handle I2S... You hook up the wires to the I2S input of my DAC. OK?
-Why would you say I am crazy for wanting Firewire and then offer a Firewire solution?


So back to square one. I would like a USB/Firewire/Ethernet solution to get bit-perfect data to my DAC for under $100. Is this clear enough for the masses?

I was going to leave the color choices untill the end. What else could make it more clear other than a clear case?

If you don't mind an internal, M-Audio makes a 192-capable PCI card that gets some pretty good reviews. Used, could be found for around that price.

The card must output I2S. I would prefer an external power supply.

the need for 192k playback is as artificial as it gets.
Firewire is good, but only recently (~2006) .
USB is not good at all, flawed because cable is too short (or what)


So you dont want to use 192k to oversample in-the-box, I guess the need is artificial. FW gives 192k tho (if the chipset is good). Cheaper than 200usd is possible.
I don know no modding guide for such soundcard but Im about to mod one myself , I just took it apart today. I2s wont be a simple thing, 'wires' arent good for this at all.
