STREAMER - WHERE DO I GO FROM HERE?


I've been using the Eversolo DMP-A8 and think it's a mid-range, feature-rich, capable, and attractive machine.  For the past few months, my focus has been on putting my system together (e.g., new caps on the amps, new tubes, getting clean power, turntable, phono stage, etc) and have felt that I've been overly focused on the analog side.  I've long wanted to work on getting my end game digital setup and pulled the trigger on a BAT Rex 3 DAC and now want a streamer that mates well with it.  I know little about streamers. . .just enough to get lost in the topic.  

Other than an easy-to-read screen and balanced outputs, what features should I look for in an endgame streamer that will deliver a significant performance boost?  I invite any suggestions.

@soix I don't blindly trusst AI.  I have confirmed with my dealer and the instructions indicate that unit is USB 2.0 / Audio class 2.0 compliant and asynchronous mode is the method through which DAC generates a high precision clock master and the computer (i.e. the streamer) is clock slaved.

What's interesting is that Chat GPT gave me an answer that correctly identified the USB port as the best connection. 

 

 

 

 

I have the Innuos Stream 1 with LPS1 power supply and Phoenix USB module, and the sound quality is quite excellent, with my Gungnir2 DAC, which I may replace in the next year.  The Innuos Sense app on my iPad is excellent and integrates superbly with Tidal.  I had an occasion to deal with Innuos Tech and Customer support, and both were superb.

The thing to keep in mind is that streamers don’t have tonal characteristics, and anyone’s individual experience is likely to be different based upon their setup.  The reason that different streamers seem to exhibit slight tonal or sonic differences, apart from digital processing differences like up/oversampling, dsp, etc., is primarily due to electrical engineering factors like jitter, power supply noise, and electrical isolation (galvanic isolation) impacting the DAC's performance.

So while they pass the same digital bits, the quality of the transport (handling of timing/noise) differs as follows:

  • Jitter (Timing Errors): High-precision clocks reduce jitter, which can affect the DAC's analog output, resulting in different perceived soundstaging or, rarely, tonal qualities.
  • Electrical Noise & Isolation: Poorly designed streamers can introduce electrical noise (EMI/RFI) into the DAC via USB or SPDIF, affecting the analog stage.
  • Power Supply: Better, cleaner power supplies (linear vs. switching) reduce noise floor, allowing for a cleaner signal, often perceived as a "blacker" background or more detail.
  • The DAC's Sensitivity: If the DAC is well-designed with good jitter rejection and isolation, these differences can become nearly inaudible. 

In sum, the interaction of these factors influence the extent to which one can hear fully the characteristics of one’s DAC.  But you do not have to spend more than $2k to get state of the art performance - i.e., vanishingly low noise levels.  

Finally, there is some evidence that even when streaming  “bit perfect”, there could be subtle differences among different streaming software platforms, based on levels of CPU usage associated with software efficiency.  However, this is again related to noise, that is, the potential for heavier CPU usage to leak into digital outputs.

Here’s a thread that explores these issues more fully:

You do not get SOTA streamer performance from a $2k streamer. 🙄  Anyone who’s compared lower models from Aurender, Innuos, etc. to their pricier models will tell you the $3k models are not SOTA.  Good performance, yes.  SOTA performance, no way. 

@mdalton - I was intrigued by your post.  With that said--and not that I know anything (I don't)--I'm inclined to agree with @soix regarding the need to spend no more that $2k for a streamer to achieve SOTA performance.  If that's true, then that

suggests that those who spend $2k+++ for a streamer are ignorant or suckers for the hype "spend more, get more, or both."   

I find it hard to believe that so many could be wrong and could save a boatload of money by buying a Cambridge Audio EXN100 or Bluesound Node Icon and get reference-level results.  

Could so many be so wrong? (In a world with $100,000 speaker cable, I guess it's possible)
