Discerning a difference between streamers is difficult...only me or common for all?

I purchased a Moon 280 D streamer with DAC, at $4K is Moon's least inexpensive streamer. I tested it against what I was currently running. A laptop computer running Tidal software through a Chord Qutest DAC. The Moon 280D immediately sounded more nimble and lively than my computer and the Qutest, even though I think the Qutest is a very good DAC for the money.

The store owner knew I was in his store to buy Sonus Faber Olympica Nova V speakers, not a streamer. But with the test against the Qutest, he'd reeled me in to buying a streamer. He then compared the inexpensive Moon 280 D with a $9K Linn streamer. Maybe I could have heard the difference if I'd spent an hour in the store listening carefully.

Bottom line, I'm very  happy with the moon. Also, if you are streaming from a computer through a DAC, and have the money, I would suggest comparing it to a one-box DAC streamer. I do believe something is lost--in jitter or the quality of the cable connection, or whatever--using a computer DAC combo.

I’m not a software engineer so I can’t satisfy your need for an explanation. But I think if you actually look into different playback and operating systems, you will find that there are differences both in the way the operating systems control the clocks and CPUs, but also in the way the digital information is handled and moved about. Audirvana, for example, converts the file into PCM and preloads it into ram before playback. HQPlayer employs a complex variety of filters. Any serious digital audiophile will tell you that Roon sounds very different from Minimserver, even sans any direct DSP intervention. Even the more basic players, like Gmediarenderer, APlayer, Squeezelite, MPD--they all present different signatures, at least in my system. Buffers, caches, protocols--I couldn’t technically say what mechanisms are at work. But the differences are deliberate in that the designers of these various players are seeking to deliver digital music in the most convincing way. You say "working to spec." But what does that mean? Honestly, in terms of digital playback we’re waaaay past the "bits are bits" stage and well into how the subtleties of microprocesses contribute to converting bits into music.

No discernible difference that these old ears can hear between streamers, although some are more convenient to use than others…all are fed to external dacs and my favorite is the Teac nt 505 (dac/streamer), also have bluesounds and WiiM Pro Plus…all good

I recently upgraded my streamer from Zenith Mk 3 to Zenith NG.  Big delta in price.  I heard very little to no difference.  I think this is a function of the quality of your DAC and its USB implementation.  I use the MSB Reference DAC with their USB Pro.  It's galvanically isolated through optical cables. My advice is to buy the best possible DAC you can.  For me the streamer is much lower on the priority list.  

I have a Bluesound Node 2i and a Innuos Zen 3, the Innuos sound is much better than the Bluesound for me, however, I am surprised at how well the node sounds when looking at the price comparison, I think the Node benefits greatly from me running it through my Denafrips Terminator 2 12 edition. The node was 600.00 the innuos 3,600. 6 times, is the Zen 6 times better, no , but it is noticeably better on many levels. When comparing the Node using its own Dac sound to Node/Denafrips, it’s clear to hear how much benefit the Denafrips provides to the Node.
