Digital Done Right: Standalone Streamers & Servers

Some drivers on the road like a little zip in their ride. The popularity of Ford’s twin-turbo V6 Raptor truck shows an example where lifestyle and comfort being juiced with extra performance proves to be a big seller. Even reasonable cars, trucks and SUVs these days offer a bit of “oomph” behind the gas (or non-gas) pedal, with Tesla's rapid-acceleration electrics leading the way.

Stoking the need for speed within the paradigm of the usefulness of a multi-purpose vehicle, for me, draws a perfect parallel to the concept in HiFi audio of “separates” versus integrated components.

Can a Raptor beat a V12 Lamborghini off the line? Definitely not, but it’s not designed to do so. There’s a place for quick and useful vehicles in a garage just like there is a place for the convenience of combining components in a HiFi system.

But what if ultimate performance is the goal instead of simplicity? Separating those components would then be the mission, as digital sources like the DAC and the streamer can improve with their own dedicated circuits, chassis and power supplies.

The topic of power supplies should come up a lot for the audiophile seriously investigating high-performance streaming digital audio and wondering how good it can get. Purpose-built, pure digital streamers and servers, at least the ones in this list, have had lavish attention paid to their power sections, with more specialized regulation and lower noise as you move up in price.

It doesn’t stop with better DC power; state-of-the-art streaming devices isolate inputs, cache files for SSD playback and optimize their software for best sound. Those components with CD-ripping drives and storage perform this task uncompromisingly and with bit perfection.

Audiophiles looking for the best that modern high-resolution streaming offers have plenty of options, such as those in this list from TMR’s new products catalog.

Aurender N200

The N200 is perhaps the best all-around streaming product that Aurender offers. It’s graced with the same power supply and digital clocking DNA of the top-tier Aurender products, but it’s slimmer and sleeker. It’s got space for two drives of storage and can act as a server, or it can operate and stream entirely using a super-fast SSD. Its impressive display can be put to sleep in “Critical Listening Mode,” for the ultimate in low-CPU use, low noise streaming digital playback. 

Top-end digital-only streamers like Aurender's N20 take these philosophies to the highest level, but at $6K, The N200 is the point where the magic really starts to happen. Lack of Roon integration may seem like a downside at first, but Aurender’s own Conductor app is a joy to use. It offers further sonic optimization than the well-known Roon can boast, caching entire songs for playback from a more stable and lower noise onboard SSD. Aurender is the discriminating choice for an all-in streaming approach.

Bluesound Vault

Again, Canadian company Bluesound offers a terrific entry point for streaming local files alongside internet-based ones with the Vault 2i server and streamer. The integrated CD ripper allows the audiophile to transition fully into the streaming world. The BluOS app connects with a laundry list of cloud streaming services, and the Vault even works with Control4, Crestron and other home integration products. The onboard 2TB is enough space to hold an impressive library, and advanced voice control via popular home internet-connected speakers like Amazon’s Alexa or Apple’s Siri feels like icing on the cake. Get a Vault and add as many Nodes or PowerNodes as you want for epic, multi-room, voice-controlled audio.

Cyrus Stream X Signature

Cyrus’ pure digital, purpose-built streaming transport easily transcends the performance of the brand’s other all-in-one or combination products, at least as it relates to streaming. Housed in the same alluring chassis and motif that Cyrus fans crave, the diminutive Stream X Signature connects with Tidal and Qobuz, and uses a proprietary software called Cadence, although BubbleUpNp fans can also use their software of choice. Cyrus’ Stream X Signature represents serious streaming at a budget-friendly price.

Aurender ACS10

Like Bluesound’s Vault, Aurender engineers wanted to offer solutions for the audiophile with a lot of CDs on hand and the goal of reducing the physical library in mind. The ACS line of products will rip, serve and stream as a one-stop solution. The onboard CD drive on the ACS10 is worth mentioning: it’s the same TEAC drive that high-end brand Esoteric uses, and it’s quiet and powerful. The fine treatment of bits doesn’t end there, however, as files are ripped using “bit-perfect” software which checks and rechecks the accuracy of the files before and after transfer to make sure they’re 100% error-free.

The rest of the unit carries the same intense attention devoted to important hardware components that makes Aurender famous in the HiFi community. Double-isolated jacks, precise clocks and solid-state caching are mated with larger drives and expanded storage capability. Also like the Vault, the ACS10 can serve as a “hub” and connect with other Aurenders on the network for a simple multi-room experience.

Aqua LinQ

When Aqua designs a digital product, the Italian company tends to go all-out. Our exclusive review of the La Scala Mk II “Optologic” DAC showed what’s possible when you combine four state-of-the-art topologies (tubes, FPGA, resistor ladder, FET output) into one purpose-built performance machine. The LinQ is no different, and adds an extra layer of transparency and resolution when connected to the Aqua DAC. The AQlink connection scheme allows the LinQ streamer to send files via I2S, which is a more advanced form of S/PDIF. This connection is as low-jitter and low-noise as they come.

The LinQ offers a lot of flexibility, and can be configured as a Roon core itself, or can be set up as an endpoint. Further flexibility comes from its optional integration with HQPlayer and even NAA transfer protocol if desired. Once dialed into your setup, the well-reviewed LinQ will shine as a statement streaming source in a high-end digital system.

Roon Nucleus+

Roon can be run on any product which, like the LinQ from Aqua, is a certified Roon Ready or Roon Tested device. But in order for the setup to work, there first must be a “core” to house the Roon program and serve music to the endpoint players. Any Apple computer or Windows PC can run Roon, and even Linux-based NAS servers can handle the job. But for best performance and ease of use, Roon offers its own Linux-based Roon cores called the Nucleus.

A new multi-zone version called the Whirlwind has just been released which includes analog outputs, but in general the Roon devices have been focused on passing a digital stream to other players on the network. The Nucleus+ has more storage than the standard version, but they both offer expansion slots for adding extra drives.
