    The Auralic Aries is perhaps the most talked about HiFi product in recent memory. The Computer Audiophile Community is probably more responsible for this chatter than most other outlets combined. It only makes sense that we would talk about, and hype, the Aries as the product is right up our alley. An Ethernet to digital audio interface, software driven and upgradeable, and an ambitious iOS application are items for which some computer audiophiles live. The Aries includes all three. I've had the Aries in my system since early July and it's time to deliver an update to the CA Community. In the early beta days I had my share of issues with the Aries and Lightning DS iOS application. I've used the Aries in combination with several UPnP servers, UPnP control points, and DACs since its arrival. Over the last few weeks the system has become increasingly stable and enjoyable to use for all my local and lossless streaming music needs. ...

    My first exposure to a new Linn technology named Exakt was at the 2013 CEDIA Show in Denver. I didn't have a chance to listen to the system on display because the show floor was very noisy, but I talked to Linn's Managing Director Gilad Tiefenbrun about Exakt. I walked away from the conversation enthusiastic about the capabilities of Exakt and about the possibilities for better sound reproduction in home environments. I'm a big supporter of using technology, but only when it's appropriate. Linn's use of Exakt technology to send lossless digital data via CAT5/6/7 cables into the loudspeakers and keep that data in the digital domain, through the crossover and volume control, until just before the final amplification stage within the loudspeakers is what I call great use of technology. Less than one year after that CEDIA show I have an Akurate level Linn Exakt system in my listening room. I had reservations about setting aside my large analog equipment, state of the art digital to analog converter, and TAD CR1 loudspeakers in order to put the Exact system in place. There is no going in to this system half-way as it's fully active with amplification attached to the loudspeakers, digital to analog converters attached to the loudspeakers, and RJ45 ports rather than binding posts for receiving the incoming signal. I couldn't even use an Aurender music server if I wanted to with the Exakt system. None of this is good or bad in and of itself. It's just a fact of using any Exakt system. There's no hodgepodge of components to select, interconnect, and hope for a good synergy. Exakt works within its own ecosystem, and it just works. After the initial setup and two weeks of extensive listening I am very impressed with the Linn Exakt technology. In fact, the Akurate Exakt DSM and Exakt Akubarik loudspeakers comprise the best Linn system I've ever heard. Period. ...

    Have a good USB DAC? Check. Want to turn it into a networked device without changing one item on the DAC? Check.

    Over the last couple years I increasingly wanted a specific product that didn't exist. I wanted an ultra simple device with Ethernet input and USB audio output. This seems like such an obvious product that should have been available since the day the first USB DACs hit the market. Especially because so many of the network addressable DACs have big problems with file types, compression schemes, gapless playback, etc… Plus, if the sound of a specific USB DAC is what the listeners want, but they also want the functionality of a networked DAC, they should be able to bridge the gap. This isn't rocket science and this isn't the 1980s. Tiny ARM based Linux compatible single board computers are everywhere. It's time for the Internet of Things and running on this IoT are millions of tiny devices that can be used to create a simple Ethernet in and USB audio out device. As The O'Jays, The Kinks, and Sharon Jones & the Dap-Kings said, Give the People What They Want. Thus, the SOtM sMS-100 Mini Server was created. We finally have a physically simple device that converts network audio streams into USB audio streams for playback on nearly any popular USB DAC. ...

    T+A Elektroakustik is a company for which some Americans have yet to acquire a taste. Yet, T+A's product styling, build quality, and sound quality have won numerous awards throughout Europe. It took me awhile to really get what this company was doing and to acquire a taste for these German designs. At CEDIA 2013 I told the Dynaudio North America team, importers of T+A, that the styling of the T+A components was less than pleasing. Then I was shown a "custom integration" rack full of T+A components and things started to click. The look of this tall rack with several uniform looking components was quite nice. Since the CEDIA convention T+A components have entered my mind several times, especially when considering Ethernet streaming devices. T+A isn't new to the streaming audio market. The company's engineers have been perfecting its streaming platform for years and know quite a bit more about this technology than many companies. One of the first questions I ask before reviewing a streamer is, does the product support gapless playback at all sample rates? The response I received from T+A at RMAF was priceless. The answer, "Of course." I felt like gapless high resolution playback was an issue T+A conquered last century and the company was on to solving more complex issues. After acquiring a taste for T+A's styling and hearing about the company's impressive product engineering surrounding audio streamers, it was time for me to get the Music Player Balanced into my system and start listening. ...

    Pixel Magic's Lumin network music player is really something special. The Lumin simply works great, sounds great, and looks great. Every audio component should at least fall into the "it works" category. Unfortunately when network audio is involved most players have issues. Some network players can't handle gapless playback, others can't handle DSD playback, yet others can't handle files with larger than average embedded album art. The list of issues or deficiencies of network audio players could literally go on for several pages. A search of the Computer Audiophile forum, Linn forum, PS Audio forum, or even Google should give readers an idea of the headaches many users go through with network based audio solutions. Contrary to popular belief the network and player setup part is relatively easy. The hard part is running into issues such as lack of gapless playback and being powerless to fix the issue. Sometimes it's a hardware issue that no amount of firmware updating can fix. Other times firmware can resolve the issue but may cause an unforeseen issue with another aspect of playback. Network audio users know exactly what I'm writing about, whether they want to admit it is another story altogether. The Lumin suffers from none of the common network audio player ills. I streamed high res, low res, medium res, sky-high res, you-name-it res to the Lumin over my network and it simply worked. Gapless DSD? Check. Gapless 24 bit / 192 kHz? Check. No hiccups? Check. Lumin is without a doubt the most polished DLNA network player I've used to date. ...

    At times things get a little complex here at Computer Audiophile. Maybe that’s the nature of both computer enthusiasts and audiophiles. The mentality that version 2.0 must be better than version 1.0 and the more work it takes the better the payoff can be seen throughout this wonderful hobby. There’s nothing wrong with exploring computer audio and taking it to the extreme in an effort to improve one’s music listening experience. In fact I encourage this every day as a way to take computer audio as a whole to the next level. However, complexity can take the fun out of almost anything. Countless times I’ve run into a computer issue and spent thirty minutes tracking down the cause. Meanwhile my friends listening to vinyl have already flipped the record over to Side B and started thinking about their next album to play. In the spirit of simplicity and enthusiasm for just listening to music I set out to use the Linn Akurate DSM network audio player as if I was brand new to this hobby. I wanted to forget about my enterprise Cisco based network with several UPnP / DLNA servers, control points, and renderers. Thus, I installed the Synology Media Server software on my Network Attached Storage (NAS) drive, used my iPad to control playback with Linn’s Kinsky app, and streamed music directly to the Akurate DSM. The experience left me pleasantly satisfied and wondering if I still needed my unusually complicated network audio configuration. This simple setup enabled me to listen to more music through the Akurate DSM and forget about how each packet was speeding through my switches and Ethernet cables. While listening I thoroughly enjoyed the very good sound quality put out by the Akurate DSM. A NAS, iPad, and Linn Akurate DSM is a very compelling package for those seeking high quality sound and simple network based audio. ...
