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.

From my fairly limited experience, I agree Ckorody's thoughts.

Depending upon your budget, hardware, and needs, I believe an outboard USB DAC is the way to go.

I was in your boat a few months ago, and recently acquired a USB DAC -- the Wavelength Brick. After the fact, I can honestly say that this is one of the most prudent decisions that I've made during my many years in this hobby.

I divested myself of a $6K CDP ($8K if it had outputs; transport & DAC were identical).

My primary front end is a turntable, so CD playback is for media not available on vinyl, or simply for convenience. And PC audio is convenience PLUS! For the few weeks I’ve had the DAC, I’ve had more fun than I would have imagined – playing more varied music as the mood strikes me, than I ever thought possible!

Because of vinyl, my goal was to improve music access, and if the USB DAC didn’t quite achieve the same level of reproduction as my CDP, I wouldn’t have minded. But much to my surprise, the opposite was true. Absolutely wonderful sonics; I believe better than before, with the added bonus of supreme convenience!

Believe it or not, the computer I originally used was an ancient PII 300mghz, with a 160GB HD.

State of the art hardware is absolutely overkill! However, depending upon how you plan to configure you system, silence IS important.

I have since bought a MacBook because of the funds I had left over after my CDP sale and the DAC purchase. Getting a multifunction PC (laptop), plus a music server, was the incentive, and this was my first non-Windoz based machine. So far, I love it.

Yep, there has been a learning curve for both the hardware and software components of my transition. However, this old dog finds learning new tricks to be fun.

Gordon Rankin’s Wavelength Audio website has some very helpful information about PC audio – take a peek if you haven’t already done so.

Lastly, if you’re going to use a Windoz based PC, your media player and hardware configuration is important. You need to bypass Windoz K-mixer. ASIO and plugins will help you do so with a player like Foobar. The same is true for J River’s Media Center, however, the plugins are built-in and less difficult to acquire and install.

On the other hand, if you have an Apple and iTunes, just plug ‘er in and let ‘er go.

I hope this helps…..
