Up to the Minute: Streaming Bits to Audiophile DAC


I have some unanswered questions from another thread, and also some new ones despite searching the archives. So I hope this thread might be a good place for all of us who are interested in state of the art audio quality from hard disk drive based files.

Kublakhan in another thread suggested using the Sweetwater Creation Stations as hardware for a PC based audio solution and so far this gear looks pretty good to me.

My questions, however, arise from the fact that there may be some disconnect between the conventions for "pro audio" and "audiophile" audio.

So as of this writing, can anyone please explain:

Why does every pro audio person seem confused when I tell them I want to use an external DAC?

What is the BEST way to extract bit for bit data from a hard drive, to export to an audiophile DAC?

Why oh why do expensive $$$ music or media servers, which are supposedly configured to optimize audio use, nonetheless require some sort of cheapo "interface" to stream the data into an audiophile DAC?

Why on earth would I want to buy an audiophile "sound card", which I presume (in addition to an "interface") also has its own DAC?

Given the options which are available for "sound card" and/or "interface" type devices, what is the BEST way to tap the bitstream and/or maximize performance of the audiophile DAC? Optical? TOSLINK? Spdif?

Given the choices I might have for the "interface" between the computer and the DAC, what is the BEST way to minimized "jitter" or other audiophile nasties? Or is that phenomenon more of a downstream issue AFTER the bitstream hits the DAC?

There is a lot of great information in the other threads about ripping, tagging, Foobar vs Itunes and a million other complications of hard drive based audio.

But for now, I would really appreciate just some basic, conclusive opinions on the best way to get bits off the hard drive and safely on their way to my speakers from an audiophile DAC.

Please advise.

THANK YOU.

I'll give it a shot too:
1) rip my CDs to WAV files on the hard drive(s) of my choice

I have found that the fast DVD-R/W drives in Toshiba laptops work great with Exact Audio Copy. They do error-free rips at 5-8X speed. This is extremely important. I purchased a Sony laptop with what I thought was a decent DVD drive only to find that it would only rip at 1X. This takes 45 minutes to an hour to rip a single CD. I returned it immediately.

2) "tag" these WAV files with album and track information

EAC has functions that you select that automatically retrieve the data from FREEDB database on the web.

3) export bit for bit perfect data without insulting my other components by using a cheesey cheap sound card or "interface"

This is tricky. There are a lot of soundcards out there and most of them have high jitter outputs. The lowest jitter will come from external independently powered converters, the best being I2S, followed by a well-implemented AES and then S/PDIF interface. The best sound comes from USB converters that use custom software drivers, not Windows drivers IMO. I would not recommend ANY internal PCI sound card.

4) implement "best execution" for connections, whether USB, XLR or some other acronym that I dont necessarily understand

Avoiding S/PDIF or "digital coax" is best if you are wanting USB conversion. USB conversion supports higher sample rates, such as 24/88.2 and 24/96. Wireless "Wi-Fi" does not support anything other than 16/44.1, but can be easier to set-up and has the wireless convenience. Wi-Fi can also sound great.

and

5) Get all of this with a minimum amount of "jitter" or other nasty artifacts into the DAC of my choice.

Again, the design and clock quality is key to obtaining the best result.

I would give you the list of components, but this would be advertising.

The SD Transporter can do 24/96.
Kana813 - Are you certain that the transporter does 24/96 wirelessly? I could not find this in the specs.

Steve N- do a search for 24/96 on SD's forum, you'll see
a number of Transporter owners report it works.
