What is the added value of a streamer over a networked dedicated Computer


Hi

I see lots of sales pitches for streamers as digital sources, and plenty on this site advocating them. I get that they're a purpose-built user interface but, apart from that convenience, including a visual display on the device, (i) do they really deliver better hi-fi sound as a source over a well set up computer dedicated to hi-fibreoriduction (ii) if so, why?

Here's some background to my question(s). I currently use a dedicated Mac Mini with SSD (headlessly) and Audirvana Plus software through a USB DAC. I tend to listen to digital files on external drives (wired connections). Some are high Definition eg Flac, some are aiff ripped from my extensive CD collection. Currently I only tend to use Spotify etc to test if I like music and invest in actual downloads of the music I like.  In day to day use the Mac Mini/Audirvana Plus (virtual) player is controlled using its remote app on an iPad on the same Network. If I wanted I could add high quality online streaming from, eg, Tidal. Whilst that would expand the breadth of music I have immediate access to, it seems to me to add another potential source of interruption/corruption of data flow. The Audirvana software overrides/bypasses detrimental computer audio elements and processes keeping the data path simple and dedicated to hifi audio replay.

So what, sound quality-wise, would a standalone streamer device using NAS or other drive storage and/or online web connection bring to the party? It seems to me it's just a digital device containing effectively the components of a computer with a button (or remote) interface. I understand the old argument that it's dedicated and not doing other things simultaneously and that computers are traditionally electrically noisy environments but I'm currently sceptical that with a dedicated computer, not being used for other purposes, and running a virtual device like Audirvana Plus which effectively switches off internal functions which might compromise sound, this is a real problem. Also it seems that a "dedicated streamer" contains many elements which are effectively computing elements. Note that I have no industry connection or monetary interest from Audirvana or Apple.

"However, considerable jitter needs to be introduced before audible effects can be heard."

Bingo. And yet people still waste thousands of dollars on DACs when a $130 SMSL would more than suffice. It takes just 5 minutes to look up a measurement. Not a bad time investment to possibly save thousands.

Before comparing the SQ of a PC and a dedicated streamer, care should be taken to ensure that all the PC and the playing software parameters a properly set so it is in the bit perfect data transmission mode to the DAC.  If not, for sure a dedicated server will sound better...

+1  @yage  For clarifying that jitter is no longer an issue with modern asynchronous mode DACs.  

- Folks who haven't actually tried Aurender+  software may not understand how effectively it can transform a PC or Mac for audio.  I'm using a similar setup, and find that SQ is excellent.  No doubt that a $3k dedicated streamer will be better, but this is pretty darn close, and may also give you the flexibility that you need for your music production ventures.

A few suggestions:

- Please give yourself a free trial month with Qboz, managed through Aurender.  Results from this high res streaming compare favorably with and often exceed those from my disk-resident files.  Not to mention opening up access to a world of music beyond my normal experiences. Believe me on this.

- I think you are spot on with the thought of upgrading your DAC/ADC.  This will be true whether you later opt for another streaming system or not.  

- For your recording work, consider a used Ayre Acoustics QA-9  ADC, if you can find one.

- Avail yourself of free room correction software (multiple agon threads on this ) to generate  a convolution file for Aurender to then manage, as well.

Good luck!
