1. A y WHERE HIFI AND HIGH TECH CONVERGE VALUE Aurender W20 Review by The Computer Audiophile Published on 04 01 2014 05 10 PM Aurender music servers have been part of my digital playback arsenal since 2011 1 was so impressed by the Aurender 510 that I placed it on my CASH List and named it the 2011 Product of the Year The 510 was the first music server Td seen that was built like 3 high end audio component with solid engineering on the inside and stellar attention to detail on the outside The S10 was IT However a couple colleagues of mine thought the S10 was a good start but there was much room for improvement It turns out my colleagues were correct Not long after the S10 hit dealer showrooms the Aurender team completed a state of the art listening room and went to work on something better than the S10 The product that emerged from this work was the flagship Aurender W20 The 20 is not an upgraded S10 The only critical component shared by the two models are the oven controlled crystal oscillators OCXO Based on several months of listening testing and comparing the W20 to all other servers I ve used I conclude the Aurender W20 is unequivocally the piece de r sistance of high end music servers Aurender W20 Hardware No Hocus pocus Just Solid Engineering The Aurender W20 hardware and software were designed by music loving engineers High end audio hocus pocus is antithetical to the principles guiding of t2. a W20 over the network sees both HDD1 and HDD2 each 3TB or 4TB depending on the model This is one item I wish was user configurable I prefer to have both drives combined into a single large drive of 618 or 8TB This would make copying files easier and space management nonexistent Currently my W20 has two 3TB drives I have an A K folder on HDD1 and both L Z and DSD folders on HDD2 If my collection music in the A K folder grows larger than a single disk can hold I ll need to reconfigure the folder structure Fortunately if I create an A K folder on both HDD1 and HDD2 the Aurender will see these as a single folder when using the folder filter button This isn t ideal but it s also not the end of the world or a show stopper The possible pitfalls of combining both drives into a single larger drive may have to do with adding either hardware or software RAID to the W20 or the fact that losing a single disk would wipe out one s entire music collection rather than half of the collection Users should worry about losing their music in the event of a drive failure because everyone has a backup right If the W20 can be setup for a single large drive I d love the ability to toggle this on or off from within the iPad application Aurender W20 Software No Hocus pocus Just Solid Software The software running on the Aurender W20 is nearly identical to all other models The only differences are related to support for hardware such as word clock input and dual

Sara s cover of Goodbye Yellow Brick Road not only sounds superb but the way she make it her own is just enough twist to get lost in the song without thinking about Elton John video Music lovers and high end audio aficionados long to hear exactly what s on a recording without their equipment editorializing The Aurender W20 delivers listeners the best shot at this true reproduction Comparing the W20 to a CAPS v3 Carbon server revealed the sonic limitations of an off the shelf computer music server Even though the CAPS v3 Carbon server is completely powered from LiFePO4 batteries it doesn t deliver the music signal to the rest of the audio chain as well as the Aurender W20 The CAPS server sounded like it was adding digital artifacts and giving a false sense of clarity and detail compared to the W20 This type of sound can lead listeners to conclude the CAPSserver offers more detail or enables one to hear more of his music than the W20 However I caution against jumping to such a conclusion Hearing things that one has never heard before can be a fantastic experience as long as those things are in the recording Compared to other servers I ve used over the last several years not including the W20 the CAPS v3 sounded fantastic and much better for the most part Now that I ve lived with the W20 for an extended period of time I ve finally found a server that I cannot top with my own build or with any other server I ve yet heard There is a tendency to

6. on Why fix what s not broken Users in need of features like DSD support can easily upgrade the Aurender software by tapping the upgrade button within the iPad application When DSD support was ready it was made available for free to all Aurender users This update included support for DoP version 1 2 DSF and DFF files sample rates through DSD128 5 6MHz via USB output and rates through DSD64 2 8MHz on other outputs Some DSD fans have ISO images of SACD discs in their collections The W20 won t play ISO images due to issues with metadata and caching however the Aurender software has a built in ISO to DSF converter Once the ISO image is converted to individual DSD files the ISO image is deleted from the hard drive Users seeking DSD to PCM conversion for playback through DACs such as the Berkeley Audio Design Alpha series currently need to convert theirDSD files to PCM one time before copying them to the W20 The W20 and all Aurender servers support PCM bit depths up through 24 bits and sample rates up through 192 kHz The Aurender iPad application is currently the only method of remotely controlling playback The Aurender team is currently working on an Android version of its application Testing is being done on the Samsung Galaxy Note Pro 12 2 and a few other tablets The team has been hesitant to release an Android version due to the fragmentation in the Android market The number of Android devices with varying levels of performance screen

8. AES output The Aurender servers feature Remote Support capability There are a couple methods of enabling this remote support one from the actual W20 and the other through the iPad application Remote support must be enabled by the end user and is only necessary if the user encounters a problem Once enabled via the iPad app the Aurender team receives an email containing very general system information such as software versions of the system software and the iPad application and any description of the problem provided by the end user Upon receiving notification of a problem initiated by the user the Aurender team can access the W20 remotely to diagnose and correct issues This remote access requires no configuration or user intervention other than enabling the feature I know people who have used this feature in the field and have been very happy with Aurender support I ve used it myself and had great results The feature seems time limited in that I ve enabled it and had to re enable it because the Aurender team didn t connect immediately I did t expect immediate assistance as the team doesn t have a 24 7 support staff monitoring and connecting to systems around the world Not even multi million dollar computers in enterprise datacenters come with that level of service without hefty service agreements costing tens of thousands of dollars per year Nonetheless this remote support feature built into all Aurender servers is very valuable It s one fea
9. al Without stability nothing else matters An app that crashes or doesn t function deterministically will only increase user frustration and possible embarrassment In high end audio circles there is nothing worse than giving a demonstration to friends or family with equipment that doesn t work Most of us have been in that situation Hey check out my new system Oh wait something isn t right It should be working I just had it playing music before you arrived honestly Official release versions non beta of the Aurender iPad application are rock solid If a feature decreases stability of the app during beta testing the Aurender team will perfect the feature before release or the team won t release it to the public Since I started using the Aurender iPad app in 2011 stability has been very good Capability without complexity is critical An app must have most of the features users want but mustn t be overly complex What good is a professional digital audio workstation as a home music server All the capabilities for playback are there but the level of complexity very high and the learning curve is way too steep The Weiss Engineering MAN301 network player has a long list of capabilities but the user manual is 197 pages of required reading I was unable to use the MAN301 without reading the manual The Aurender iPad application is very capable and easy to use without instruction Mastering all the ins and outs of the app requires a few quick tips f

11. his team The state of the art listening room at Aurender s Seoul Korea headquarters is used to verify engineering changes and concepts implemented in Aurender products When squeezing out every ounce of electrical and mechanical noise from a product a very quiet listening room with highly resolving components is a requirement The Aurender listening room contains 303100 components from Constellation Audio digital conversion and clocking from dCS and loudspeakers from Magico Several items separate the Aurender W20 from not only the Aurender S10 but most music servers on the market At the heart of the W20 design are the main motherboard and physically separated and isolated audio board Both items were designed in house by Aurender engineers When designing a flagship product it s necessary to design one s own audio boards However designing one s own computer motherboard is expensive and requires a level of expertise not found at many high end audio companies A major advantage of designing one s own motherboard is the ability to eliminate or drastically reduce electrical noise Most commercial motherboards are designed to a very low standard compared to a high end audio component Commercial board design is often controlled by accountants seeking to lower the price rather than improve quality and features according to Wavelength Audio Founder and Godfather of high end USB audio Gordon Rankin Gordon designed many motherboards for very large compu

13. ically audio board are two banks of lithium iron phosphate LiFePO4 DC batteries These banks alternate charging cycles to eliminate negative performance effects of low batteries No user intervention is required the audio board is always powered by these batteries The audio board is also isolated from annoying ground noise emanating from the mains outlet powering the rest of the server An additional bank of LiFePO4 batteries is used as a UPS uninterruptible power supply when power is removed from the server altogether This temporary battery supplies the mother board hard drives and OLED display enabling the server to shutdown gracefully and inform the user what s happening via front panel display The W20 s batteries are specd to last 3 000 charge recharge cycles until they reach 80 of capacity If the 0 is used eight hours per day 365 days per year the batteries should last about 40 years The Aurender W20 features two AES EBU outputs so it can operate in single or dual mode AES In the simplest of terms single AES uses one cable and dual AESuses two cables Both single and dual use digital cables with XLR terminations on each end This is one major differentiating factor between the W20 and nearly all other music servers on the market The reason for dual AES on the W20 is that some very high end digital to analog converters from companies such as dCS Esoteric and Chord Support or require dual AES for sample rates over 96 kHz The ultra rare
14. ightmare for browsing more than 100 albums Aesthetics that serve functionality can be as simple as a user interface color that is easy to read and doesn t shock one s pupils when viewed in the dark The Aurender iPad app is visually very nice and serves the end user well For example the letters of the alphabet along the right edge of the screen are very subtle and are only highlighted when in use This helps keep the user s mind on music rather than a cluttered interface resembling an Excel spreadsheet The Aurender iPad application features a slide able window to view album covers yet still view the queue When visible this window enables easy selection of music in one s entire collection or the limited number of tracks in the queue This same slide able window covers up lesser used controls buttons and metadata yet these features remain easily accessible with the flick of a finger This visually pleasing sliding window serves functionality One item within the app that appears to serve no purpose but to delay the users navigation is the spinning of album art and page peel when viewed in full screen mode For example when tapping the currently playing album s cover image in the upper left corner of the app a full screen image of the cover art appears On this screen the user can switch to view the queue in full screen but after tapping the button the entire window either spins around 180 degrees or does the PowerPoint like page peel effect on its wa
15. rom someone in the know such as a dealer but general use of 99 of the capabilities is easy and intuitive The Aurender iPad app features several different styles of browsing one s library such as by Artist Album Genre Song Composer Conductor and even by folder Users can also create folders on the Aurender s drives that appear across the top of the iPad app For example I have all my DSD content in a DSD folder on HDD2 The iPad app displays a button titledDSD that when tapped displays only the content in that folder The display isn t folder like at all rather it shows the album covers album title and artist name Since the beginning days of the Aurender iPad app it has featured press and hold capability When a user presses a finger on an item such as an album a popup menu appears with options The Aurender press and hold options include Play Now Play Random Replace Queue Add To Next Add To End Show Album Cover Artist Album and Add to a playlist among others Press and hold capability decreases complexity greatly It surprise me every time I use an app without this capability Selecting an album or track then finding how to accomplish the task at hand via a button somewhere add to next etc or to find out the capability is missing because of lack of GUI space is preposterous in 2014 It was almost preposterous in 2011 Press and hold with the correct amount of options is mandatory for apps to be in the top tier of capability wit
16. rstand what I mean when I say this is a complex system capable of delivering fantastic results There are other methods of clocking without this W20 dCS RS232 communication but the results aren t nearly as good as this preferred setup For example the DAC could lock on to the incoming audio signal reading the sample rate as the audio comes into the DAC Or a user could manually set the clock on a DACbefore switching sample rates Both of these are less than desirable The dCS Aurender communication is terrific Another more traditional way of getting excellent sound quality is to send word clock out from a DAC into the W20 This places the clock as close to the DAC as possible actually in it as preferred by some manufacturers and listeners Fortunately none of this clocking business is necessary if one doesn t have a component capable of sending word clock to the W20 This should cover 99 of users as most DACs do not feature word clock in or outputs The W20 is capable of stellar sound quality with or without an external clock feed When using the W20 with my Alpha DAC Series 2 I simply connected a single AES cable between the Alpha and Aurender This same configuration was used with the EMM Labs DAC2X in my system Complexity isn t compulsory for quality An external clock feeding the W20 should be considered the icing on the cake when used in the correct system In addition to working with dCS on DAC Master Clock communication the Aurender

21. t Listening The Aurender W20 is built for music playback only It has no CD ripping capability and no user interface for music management In my experience this is just fine I already have a computer or two or three with which I have CD ripping software XLD on Mac OS X and dBpoweramp on Windows and music management software JRiver Media Center It s likely that all users reading Computer Audiophile or considering an Aurender W20 already have a computer for ripping and music management as well Once a user s music is moved to the W20 there is no need for another computer There are several different work flow options for populating an Aurender full of music and updating the unit after each new music purchase Its possible to connected a USB hard drive directly to the W20 and have the unit automatically copy the files to the internal hard drives Techies often call this method sneaker net as it involves walking the files from one location to another There s nothing wrong with this method its just not the most efficient It s also possible to rip CDs directly to the W20 and to download new music from sites like HDtracks directly to the W20 over the server s Ethernet connection This method is the most efficient Editing metadata can be done by pointing an application such as JRiver Media Center to the W20 s hard drives All the music on the W20 then appears within JRiver Media Center and all metadata changes are save directly to the W20 The method I u

24. ture that really separates the Aurender servers from a Mac OS X or Windows based music server maintained by the end user Another software feature that increases the Aurender value proposition for many users is the ability of the servers to run for months without user intervention required There are no security vulnerability patches that must be installed immediately and there is no fear of impending doom such as that associated with Microsoft s end of support for Windows XP on April 8 2014 After this date Microsoft will no longer release updates for Windows XP There is speculation that malware creators are holding back a barrage of viruses and exploits until Microsoft s support ends After April 8 it may be game on for hackers and end users may be SOL On the other hand April 8th may come and go just like Y2K without any major issues for those who have prepared and even those who called the Y2K bluff like Italy and Paraguay back in the day For some music lovers the thought of updating a music server or even reading about potential issues however real or benign is enough to sway them toward a canned server like the W20 The Aurender W20 works like a toaster When bread is placed in a toaster the user will have toasted bread in a matter of minutes Period When music is placed on the W20 the user will have music at the ready day or night for months on end Period Aurender users without issues or the need for more features can simply keep on keepin
