This list is preposterous—not a single one of these steamers is worth the price by a long shot, and this is a glaring example of the folly with trusting corporate-funded review sites.
First of all, a digital music stream is a digital music stream—ones and zeros—it doesn’t “sound” like anything. If we’re talking about “pure” streamers with no integrated DAC or amplifier, they’re all going to produce identical sound qualities, and that will solely be determined by the quality of the master the digital format was sampled from. All one needs is a simple RPI or Volumio-based microcomputer to achieve the best “sounding” streamer one can buy, for any price—it’s just a fancy network transport that extracts some metadata on the path to your DAC.
There is only one prefabricated streamer-only option on the market today, that comes with a full set of features to allow the highest level of audio reproduction possible, that is at all worth it’s asking price, and that’s iFi’s Zen Stream, for$399. It’s basically a Volumio-based RPI packaged in a nice, simple enclosure, with both USB and S/PDIF inputs and a USB, TOSLINK or coaxial output to connect to an outboard DAC. With a USB connection you can transmit the full spectrum of sampling sizes, up to 32 bit PCM 384 and native DSD 256 (their upscaled Neo Stream supports PCM 786 and DSD 512, for those that can find any media that offers that).
It’s fully Roon-ready, has discrete, isolated ports for Tidal and Spotify Connect, Signalyst’s HQPlayer, Audirvana, AirPlay 2 and DLNA, and will support Qobuz, Foobar2000, J River and just about any other format you could ask for. And it has everything anyone could possibly need to achieve the highest possible sound quality available from a network audio transport. Again, you can achieve all of this with an RPI, it just does all the work for you for a bit more cost.
Beyond that, streamers that come with integrated DACs are another story, but even those are all going to sound identical unless the DAC is really a mess. NONE of the choices from this list offer anything beyond what I’ve mentioned can provide, other than a fancy/costly GUI and other crap you don’t need, and if you use Roon or Audirvana you don’t need a GUI anyway.
the Naim and Cambridge Audio selections on this list are downright highway robbery. I’d love to challenge these authors to prove empirically why they sound “better”. They cannot. Buyer beware.
