    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. ...

    How do I review this product without sounding like a book of audiophile adjectives exploded on my keyboard? The Peachtree Audio deepblue music system will likely be reviewed countless times and have more HiFi one-liners written about it than I've ever heard. To use an idiomatic phrase I guess it is what it is. deepblue is a surprisingly better product than I thought could come from its smallish size. There are only so many ways to rearrange drivers in a small chassis. Most products like this offer different spins on the same thing. Average performance using average components sold at above average prices. The deepblue music system offers much better performance than I've heard from anything in its class and at a better price than even commodity components from giants of this industry. A $399 product that sounds this good and is very easy to use is a dream come true for audiophiles looking to spread the word about our wonderful hobby. Take note, the new HiFi ambassador to the world is here and its name is deepblue.

    Sooner or later audiophiles come to the realizations that every component flavors the sound and that there isn't a single best flavor. Accepting these two facts eases us into the world of endless enjoyment provided by this wonderful hobby. Researching, selecting, and auditioning new components can be pleasurable when our sonic tastebuds are the only things that matter. When visiting a chocolatier we may ask for recommendations or for the most exotic or popular truffles. Tasting each type of truffle is a blissful experience that frequently leads us to prefer a specific flavor. Regardless of each ingredient's purity, source, or popularity the final decision is based on taste. Selecting audio components is no different from selecting fine chocolates. The colorful sights and sounds of my McIntosh MC275 may be equally as enjoyable as my impeccably engineered Spectral DMA-260 solid state amplifier. When I'm listening to music rather than equipment my audio system is comprised of components that best bring out an emotional response to my favorite albums. Over the last few weeks nothing in my listening room has been as essential to my musical enjoyment as the Luxman DA-06 digital to analog converter. The Luxman DA-06 DAC is as rich and smooth as a Diane Krön truffle yet as pure as water from France's Auvergne region. Like a good book the DA-06 had me hooked on its lush qualities from track one. ...

    Intro
    The following guide was designed for audiophiles. The guide describes UPnP based home audio reproduction, provides use pro and cons of UPnP, examples, and recommendations for successful UPnP audio implementations.

    Overview

    Network based audio can be delivered using several different protocols and technologies such as UPnP, DAAP (Apple), and Ravenna among others. UPnP is the most common network audio protocol in use today. It's used in both two channel single room systems and whole house network audio distribution. Ironically UPnP is extremely simple for end users and a bear for product producers. The more one digs into the UPnP protocols the more divergent information with common frustration one finds. This guide will not turn a novice into an expert. I hope it will provide all the information computer audiophiles need to understand and enjoy UPnP based audio playback. ...

    High end audio can be a polarizing hobby. Audiophiles like to select a product or technology and support it vigorously as if they have a large financial interest in its success. I was born an audiophile. I completely understand the desire for one's selection to be validated by the audiophile community. I also completely understand how unhealthy that desire for validation is and the neurosis it can cause. Audiophiles, myself included, must realize the products we select today will sound just as good in five years regardless of competing products, newer technologies, and others' opinions. One polarizing topic in computer audio is digital interfaces. Two digital interfaces that have strong vocal support from users are USB and Ethernet. Users of one technology frequently turn a blind eye to the merits of the other technology and won't even consider its use. Many users selected one technology a few years ago based on the information available at that time and refuse to update their own knowledge for any number of reasons. This leads to armchair engineer arguments based on half truths and old information. These discussions are a disservice to all readers. Based on my experience with both USB and Ethernet interfaces it's clear to me that both can sound excellent and both will have a strong presence in high end audio for the foreseeable future. One Ethernet interface that caught my attention a couple months ago is the UPnP AV 2.0 / DLNA compliant Simple Design Rendu Ethernet to S/PDIF Converter. Admittedly I was drawn in by the features and specs, notably its ability to play DSD, 24/192 PCM, and gapless audio streamed over Ethernet. I've since listened through the Rendu for countless hours and put it through a number of network audio tests. At first the Rendu was a bit picky and had some playback issues. Today using the newest firmware I'm happy to report the Rendu works very well and continues to sound very good. The Simple Design Rendu Ethernet to S/PDIF Converter is a product to watch in both two channel and whole house network audio. ...

    This story starts in July 2011 at the California Audio Show. That's where I was introduced to the Aurender music server team and where I had my first opportunity to use the server. I was immediately impressed by the product and the people. Everyone in the room knew their stuff. I asked question after question about the server's capabilities and the team's design decisions. I received polite and comprehensive answers to all my questions. I also asked if I could shoot photos of all the internal server components and was given the simple answer, "Yes, we have nothing to hide." I walked out of that room feeling refreshed. The people I'd just met weren't jaded from decades in the industry yet they had more music server knowledge than 99% of the exhibitors at the show. Fast forward to the end of February 2013. Days after Korea elected its first female President I touched down at Icheon Airport on a trip to speak at the Seoul International Audio Show and visit the headquarters of the Aurender team. I enjoyed meeting computer audiophiles at the show despite the language barrier. Furthermore I gained additional respect for the Aurender team, the company, and its products. ...
