dac and streamer or seperates

@russbutton 

Cool system.  Are your speakers DIY? If so, nice woodworking!

You hold a viewpoint that “bits are bits”. I’m curious if you’ve actually auditioned any dedicated streamer. Is your opinion based on belief or direct experience?

If the latter, I can respect that though I would then suggest there are other facets at play. For instance, some streamers are clearly built to be convenient. They are a simple PC packaged without the attention to detail toward sound quality, but are inexpensive. If you auditioned one of these and concluded no difference, I wouldn’t be surprised. 

Of course, you do raise some good points. A PC makes a very functional source and music library. And, many of us (me included) spend large sums of money improving (chasing our tails?) our system. It’s a hobby and I hope that all who do follow this path are able to easily afford it. 

But I will stand by prior comments in this thread. While a good DAC is important, so is a good source. The improvements made by a good streamer vs. a PC were as striking (or more so) to my system than my DAC upgrades. And, very easy to hear. 

Clearly to many of us, bits are not just bits. And it’s not related to our wallets. I don’t toss money away for fun. I’ve personally evaluated and passed on a lot of $$$ gear (including DACs >$25k) that I could afford but which didn’t bring the improvement expected. 

So, if your viewpoint is based on experience - that’s great. However, if it’s based on the understanding that you just need to get the data there uncorrupted, that is a viewpoint not supported by the direct experience of others. Or, even the science of data transmission. Digital data travels in analog wave form. EMF and other noise is carried along for the ride.

Best,

@mgrif104 You write:  "Digital data travels in analog wave form. EMF and other noise is carried along for the ride."

So what you're saying is that you don't believe that the transfer of digital data from a PC to a USB DAC is inaccurate and that it is accurate from a streamer device?  Is that right?

If I copy a music file from my Linux laptop PC to any other machine, I guarantee you that the cksum will show that the file was transferred accurately, bit for bit.  I am in Hawaii and know that I can reliably copy data files over 2500 miles, across the ocean, and the cksum will show that the copy went perfectly.   

I fail to see why that would be different for a data copy to a USB DAC (which is also a coputing device in its own right).  Once that data is at the DAC, what happens is a totally different animal. 

Why is it that a DAC is incapable of accurately receiving a data file from a PC?  Why is it that data traveling 2500 miles across the Pacific Ocean is more reliable than a 3 foot long USB cable?

 

@russbutton 

not what I’m saying at all. Yes, digital data is represented as 1s and 0s. But, it is transmitted as a voltage across a wire just like any other signal with a rise and fall to that signal that is interpreted as a 1 and a 0 when it reaches a certain value. You probably know that you can transmit digital data across an A/C circuit. The data is in there. With a whole lot of other signal.

I completely agree that the digital data received from a PC vs a streamer (a type of PC optimized for audio quality) will be identical.  What I don’t agree with is that those two data streams must sound identical after being processed by a quality DAC. Direct experience tells us otherwise. 

If you’re an audio fan pursuing better audio quality- which I presume most of the people who post here are doing, I’m just suggesting you  challenge your belief and experiment.

Of course, it’s fair to point out not all systems will benefit. Certainly not all DACs will benefit. But, some do to great affect. I once held your view. But I tried something different and was pleasantly surprised. 

@russbutton most of the seasoned audiophiles here have experimented with different streamers, DACs and network components. FTPing files and knowing how to do checksum in Linux does nothing for your credibility when it comes to audio.
There is plenty of material to read to learn how streaming works on these forums and internet in general. YouTube has few good channels where this subject is discussed and explained at length. Spend some time educating yourself.

One other thing, the OP had posted a specific question. Derailing the discussion is bad form. Stay on topic.
