Are streamers digitally enhanced?


I had a conversation yesterday with a studio engineer friend and I was telling him about the sound of my Innuos Pulse. He has heard my system with the Node 2i and was skeptical about how much difference a better streamer could make. 

After I described improvements in soundstage and overall sound quality he remarked that it sounded like some digital enhancement, similar to a studio plugin, was part of the higher end circuitry. I offered that it was revealing, not enhancing, and he replied "how do you know". 

How do we know? Digital circuitry is controlled by software/algorithms and these can't be readily seen like hardware. When new hardware comes out, reviewers can open the hood and look inside. But what do we know about how streamers or DACs are processing the signal? Is the goal purity or beauty?

I don't see how a streamer could possibly alter the harmonics or tonality/tonal balance of an audio system. It is only the apps loaded into streamers that could possibly affect one of these two parameters of sound quality, music players such as Roon, Qobuz, Tidal, etc. and DSP engines.  To claim otherwise  is arguing that digital packets of 0 and 1's have inherent tonality/ timbre. I  also don't  see how any music player app or dsp engine can change timbre, timbre/harmonics live solely in the analog realm. On the other hand I do agree the apps and dsp engines could change the tonal balance.

 

Streamers sole impacts are in resolution, transparency and presentation, this why minimizing noise and providing highest quality clocking is so important. When people are claiming their streamer adds some character to the sound they are conflating the contributions of other parts of their audio system with the streamer. A high quality streamer simply allows the 'color' of the rest of the system to shine through. The color, harmonic texture comes solely from the analog components of system, the only digital component that can alter this is the analog output stage in a dac. No network or digital data processing component has a 'sound.'

...'digitally enhanced'....

I agree with your studio guy. If there is a difference in sound with a well engineered streamer, it is being deliberately introduced.

From Chat GPT

If the streamer outputs bit-perfect data and doesn't introduce jitter beyond the DAC's rejection capabilities, there should be no audible difference.

Most well-engineered DACs (especially those with good jitter rejection and galvanic isolation) will perform identically regardless of whether they're fed by a Raspberry Pi, a $100 streamer, or a $5,000 one.

 

In blind tests, assuming a bit-perfect, clean digital output and a competent DAC, streamers do not impact audio quality. Differences reported are likely due to implementation flaws, system noise, or psychological bias.

 

 

The DAC output parts would have a "sound"

Streamer isolation, power supply design, clocks make a difference if nothing else you can hear more of the music.
