60dB is a reasonable power range for truly high-fidelity audio. That's a 1,000,000:1 power ratio - or a milliwatt to a kilowatt of power, to produce normal program levels. Very few amps produce a kilowatt of power, and those that do aren't real good at doing a milliwatt. And even if the amp can pull it off, most speakers other than high-quality horns will crap out (or blow out) long before then. So a *really good* system might do 40dB dynamic range (10,000:1 ratio) decently. Brutally clip or compress 10dB of peak, and lose 10dB of low-level detail. Your typical "home theatre" stereo crap is in the 20-30dB range, which basically means it is constantly clipping or recovering from clipping, and much of the low-level detail is lost.
The reason for the distinct "sound" of most audio equipment isn't SNR or THD or bandwidth, but rather how it recovers from overload conditions and how much low-level signal it loses. This stuff isn't easy to measure (it's much easier to analyze static signals than dynamic ones), so they produce the numbers that look good instead and claim that this somehow represents quality. When is the last time you saw THD measurements for a speaker? They don't do that, because 10% THD is really good behavior for a speaker, and that looks bad next to the

I would imagine that there is a burgeoning market for audiophile sound cards; solid engineering and impeccable quality are more important to me than "3D Simulation" or "32 voices" or any of the other crap that the marketing department invents.
I'd like to disagree. An audiophile-class soundcard just doesn't justify the cost which hardware manufacturers would put on it, and doesn't really find much of a practical application for most end-users. The mainstream can't tell the difference between an mp3 sampled at 128kb/s and one sampled at 196 or 256, and the marginal increase in quality doesn't really justify the space and expense of a better card.
However, as an avid gamer, I can attest that positional 3d sound, especially in first-person style games, adds a great deal to the experience and can improve gameplay, especially in games like counter-strike, where one overly loud footstep can mean sudden death.
I'm not knocking your hardware hacking skills, I'm just saying that high-end audio cards would, like most other audiophile equipment, be a niche market at best, and the stuff you dismiss casually as marketing crap appeals to a wider market than audiophile would, which means more dollars for the card manufactuers.

For the person who asked about Firewire - Stereo audio bitrates are fine for USB, you just need to have a little buffering in the device. I think the reason nobody's bother to put a 1394 chipset in an external sound box is that if you have Firewire you probably already have decent sound. This may change, or with USB 2.0 it may not.

I was intrigued and went looking to find that there are quite a few [audiomidi.com] options [edirol.com] out there right now already, and this Creative entry is just yet another addition to the selection list. Note that Creative would probably be the last company most musicians would look to as a leader in the high fidelity audio field.
While many people have rightly mentioned that USB has ample bandwidth for 2-channel audio (though even that at 96Khz/24bits hits 4.6Mbps - 96000 * 24 * 2): Note that this device claims Dolby Digital 5.1 -> Now I don't know if they do the decoding in the external box, or if they actually send 6 streams, but if they send six separate streams that's about 13.8Mbps (and of course USB is limited to 11Mbps).

I want multiple tracks! (Score:5, Interesting)
1. Start with 4 balanced inputs, each one with its own super-shielded A/D converter. (Possibly increase to 24 inputs for studio models.)
2. Instead of having an analog mixer, write all four of the streams from the four inputs to the hard drive at 16bit/44kbps ("CD quality"). All the mixing can then be done digitally, after the recording session is done. This is what musicians are used to from the bad old analog days when we all had a 4- or 8-track in our garage: we jam first, and then take our time mixing the multiple tracks down to 2, applying whatever effects necessary to get it to sound right.
Current amateur gear for the computer (like this box) requires you to record two tracks (L/R) at a time, and most bands don't work that way. This either forces you to mix the whole band as you record, but then you can't turn up the drums or equalize the bass after the recording is done, because they're all mashed together. If you want that sort of control, you have to record the drums alone (playing to a metronome), then the bass, then one guitar, etc. This process really kills the joy of home recording, and it kills any band chemistry that would come through if you played "live."
The obvious solution is to allow the simultaneous writing of more than two tracks to the hard drive. That way, you can play live but also adjust the individual instruments in the mixdown.
I'm sure tools like this exist, but they're made for studios or pros. But, there is no reason why the thing I describe would have to be expensive. Really, it shouldn't be more expensive than this external Sound Blaster, because the base model doesn't need all the fancy in/out MIDI and optical stuff. I know I would pay about $250 for the contraption, and I'm poor. If I can afford it, many people can. There is no way it would cost that much to make.
The only question is how many tracks USB can carry before it's saturated. Since it appears it can carry two at 24bit/96kbps, it should carry at least four at 16bit/44kbps. That would be enough for me. It may well be that any more than this would require SCSI or Firewire. Maybe also RAID. Fine. None of these things are out of the reach of almost-ordinary joes anymore.
Now if I could get my basement tuned to give good sound and rent some pro microphones (and maybe a mixer), I'd have a home studio as good as any other.

Echo's products also come with a very nice software digital mixer, which allow you to mix any input to any output. Recording software such as Sonar works well for recording multiple channels at once, at 24bit/96kHz (although I only use 44kHz).

However, I'm wondering that the impact of USB will be on latency. IIRC, the first generation of external cards still used a PCI slot to connect the external gear to the CPU.
For example, their Audigy Platinum card supports ASIO (Audio Stream Input Output) for low-latency access, but I don't see the same thing on the Extigy.
Of course, Extigy doesn't appear to support Firewire (or as Creative calls it, SB1394) on this card either.

The printer every once in awhile just decides to lose connection with the I-Opener. Luckily, it doesn't happen often so it's not a huge concern. I imagine it is also related to the VIA USB controller problem.
The ZIP CD-RW drive works fine.
Of course, I'd be judging USB badly if I just mentioned how a few devices misfunctioned connected to a modified Internet appliance... Except, I've had trouble with USB devices on my ASUSm motherboard BX chipset PIII 850 system as well as on a IMac.
The PIII seems to hate USB mice. Everything else worsk great - USB mice just never show up... Go figure.
Most common problem on the iMac is that devices simply will not show up until you disconnect and reconnect them a few times. Most notably, this applies to my Canon scanner and my Microsoft cheap-ass sidewinder joystick. The scanner usually works after two tries, the joystick - that's a different story; sometimes I give up before I can get the computer to recognize it.
Overall, USB seems to be a general pain in the ass - I'd gladly buy internal cards over ANTHING USB whenever possible.

I bought a pci usb card for my sister's computer.. attached mice, scanner (hp3300), and a printer. No problem.
One machine of mine has an AMD Viper chipset, due to a bug in the chipset.. it will cause my system to do a hard reboot occasionally. I use a mouse on this system with no problems, but my handspring visor will historically crash it quite quickly.
Pentium II, Intel chipset. No problems at all, tried the Visor and an Epson printer.
Asus BP6, Intel PII board.. same machine, different boards. Mice, Visor. No problems.
I wonder why USB sucks so much. It works fine for me (minus one due to the fault(s) of AMD)

An out-of-box sound card makes a lot of sense because you avoid the crazy RF environment in your computer case. I think Creative have a good idea with this, and the next logical step would be to include video (since the thing has a remote control anyway). I'm not saying the thing should have a built-in 3D card; that would be stupid. I'd just like a nice, hardware TV tuner (those parts are dirt cheap), and maybe also a TV out.
Of course, the USB bus can't take all that, so the thing would need its own PCI interface, but then it would kick ass.

CDs mixed for radio play are your problem (Score:2, Informative)
I'm tired of these lousy sounding CD's. People only think they sound good because 99% of them have never heard music reproduced at a higher quality
Your beef should not be with the format, but with the mixing and mastering. Many pop CDs that seem to lack punch sound that way because they're mixed for radio play, and FM radio has a poor dynamic range, so naturally you lose the kick in the kick drum.
Re:No need for 96 kHz or for analog (Score:2, Interesting)
Digital audio is poorly designed. According to the Nyquist theorem you refer to, 48khz is enough to reproduce 24khz audio signals, IF the phase of each frequency is known. Otherwise you could have a 24khz sine wave that is coincidentally sampled only on the 0 amplitude points which would make it be recorded as silence. To make up for this problem, higher frequency rates are needed. If you are sampling at 96khz, then for a 24khz sine wave, there is no possible way to only be sampleing it at the 0 amplitude points since you would be sampleing the wave 4 times per cycle. 192hz also shows up, and that is still only sampling a 24khz wave 8 time a cycle.
A superior system would be delta sigma modulation (google it for additional information) which uses 1 bit encoding with typically something like a 2.8mhz sampling rate for a frequency responce range approaching 100khz.
As to the proper number of bit for PCM, the big problem is that we hear volume logrithmically but currently digital audio records linearly. So while for high and moderate volume, more bits are deemed unhearable, but for very quite things (like quiet passages in classical music), the extra bits come in handy very quickly. The extra bits are also very handy for DSP type tasks, although one could arguably truncate them after processing if they think the log argument is BS.

I'm aware that sampling discards the sine component of tones at exactly the Nyquist frequency.
Otherwise you could have a 24khz sine wave that is coincidentally sampled only on the 0 amplitude points which would make it be recorded as silence.
Correct, but it can reproduce 23.9 kHz tones perfectly (phase and all), requiring only a convolution with (a windowed version of) the sinc function.

In other words, a 1-bit linear sampling rate with a noise-shaped dither pattern.

I understand this, and recent lossy audio codecs such as MP3 and Ogg take this into account when constructing quantization tables. Heck, even the mu-law encoding used on telephone lines is floating-point (i.e. approximately logarithmic).
but for very quite things (like quiet passages in classical music), the extra bits come in handy very quickly.
Even if we get into a whisper-quiet passage played at 30 to 35 dB SPL, and 16-bit linear PCM begins to use only the region around +/- 127, the ear still can't hear the quantization noise because it's 1. below 0 dB SPL and 2. most likely shifted up into the 16-22 kHz range, where the ear often can't reliably hear even 30 dB SPL, with the noise-shaped dither patterns commonly used in modern CD mastering.
The extra bits are also very handy for DSP type tasks
You're not supposed to do DSP on music you don't own rights to; you're supposed to listen to it.
Re:Stereo Component? (Score:2)
I cannot see any reason this device would be helpful for you.
First you need a server. Just run one of many mp3 players on the machine and control it externally via a program/webpage. Or run ESD, NAS, or ARTs on the box, and give it any sound data you wish. A maximum of 30ft of Cat5 to the server is fine.
Regardless of where the sound is coming out of, it still needs to get fed to your stereo.. so just run some cables from it to your stereo. So, run some cables.. whatever the length is from your server, run it. I don't know how long certain cables can be, but I'm sure optical ones may reach quite far.
The only reason you would need this is if your server does not have any existing soundcar, but then again.. you could just get a regular soundcard which would probably be both cheaper and better quality.

But you could use IR too, for a remote control. There are lots of things you could do, it just depends on how much you wish to spend.. and what you currently have available.
