 Ik had nooit gezegd van Henry Audio wanneer een vrouw me vraagt om hun dak te vervelen. Minuut later, Bergerstrand Bergersen van Henry Audio respondeerde dat hij dacht dat het een goede idee was. Dus waarom niet? De web bracht een suur en een suur. Een van de suurste dingen is de collaboratie tussen mensen van alles over de wereld. Het bracht als Linux en veel andere open source initiaties. Zoals dit kleine en afvorderbare USB dak. Het is al de 3e incarnatie van het dak, wat waarschijnlijk betekent dat er veel feedbacken van de communiteit worden ingebouwd in de volgende versie. Als je interesse bent, ga naar de Henry Audio website en bezoek de communiteit. Er zijn waarschijnlijk honderds pages over welke toppen op dit dak. En ik betekent honderds pages op iedere toppen. Dus als je de tijd hebt om te spenden, ga naar mijn gasten. Ik zal de dak als een van de geluid producten die werkt uit de bovenkant, die in het verhaal is wat het is. Als je dan voelt dat een alternatieve vertrekking is, of maakt hardware adjustmenten, dan voel je ervaring. Voor suggestie en support, de communiteit zal de enige plek zijn om te gaan. De houding is simpel en functioneel, meisering 114 x 33 x 112 mm. De houding houdt alleen de logo, de modelnummer en de power led. De rear heeft een type B USB input, klikken voor programma en resetting, wat ik niet gebruikt, en de analoge uitvoers op RCA. Dat is allemaal mensen, leuk en makkelijk. De print- en circuitboard heeft veel openheden, testpoorten en plekken om de printraders te solderen. We gaan niet dat doen en judgeen de DAC zoals het is. Het is gevolgd over dezelfde USB die de audio-bit zorgt. De 5 volt DC van USB is lokale convertereerd naar 3.3 volt door ADPth 151 low drop voltage regulators. Voor de DIY'er kan meer voedingskonditioning hier bevinden. De procesing is door de ADMOL AVR32 programma microprocessor. Twee precision crystal oscillators drive de AKM4430 DAC chip dat direct uitvoert analoge signalen op 2 volt max. Om dat te achieveren, gebruiken charge pumps, vormd door een collectie van capacitors op de DAC chip. Vanaf daar is de analoge audio direct direct aan de 2 RCA connect. Zoals met de uitzicht heeft er zoveel te vertellen over het zetten en gebruik van de Henry Audio. Just connect a USB cable tussen de DAC en jouw digitale source en connect de analoge uitvoeringen met jouw stereo. Only if you use a Windows computer, you need to download a driver from the Henry Audio website. Computers running Linux or Apple OS and network breaches I know need no driver. De rest is up to the software you will use. If you go for quality, you do need a bit perfect music player and you need to bypass the mixer if that's not taken care of by the music player software you use. The fact sheet downloadable from the Henry Audio website gives a clear description. By the way, this is not unique to this DAC. All modern DACs need this approach. The sound quality a DAC offers depends partly on the quality of the input signal. I don't mean the quality of the digital encoded music, but the quality of the USB signal, timing wise and noise wise. See my video connecting your DAC number two, how digital can go wrong. Let me describe the way I test USB DACs. First the Henry Audio DAC was connected to my Apple MacBook Pro. Music was played from Roon with all DSP and digital volume functions disabled. This gave a firm and deep low, a good mid-range and a somewhat harsh high end. Simbulance control could be better, symbols were edgy and violins had a tendency to harshness at high levels. The stereo image was relatively shallow. I've seen the same with other USB DACs costing about the same, maar also with more expensive ones. It is due to the noisy and jittery signal coming from a computer and it's even worse when using a laptop due to the electronics that drive the screen. The cue I use is the old DAC ADQ USB isolator and an sBooster power supply. The old DAC provides galvanic separation and decouples the USB power line when an external power supply is connected. By using an audio-grade power supply like the sBooster or Ultercamps or at a somewhat lower level the Audiophonics LPSU25 or iFi Audio i-Power things get considerably better. I use the sBooster BTOW PMP First Generation. The lows remain the same. The mids opened up somewhat more while the stereo image got more depth and focus. But the biggest difference was in the highs that cleaned up considerably. Now it's not realistic to spend almost 500 euros to have the Henry Audio sound better. But you might try to use the Audiophonics LPSU25 or iFi Audio i-Power by using a cable that feeds the USB signal from the computer to the DAC but cuts the power line to facilitate an external power. I actually think that Henry Audio should have such provision built in. A simple 5 volt power input connector that cuts the USB power feed. Another solution is to use a network bridge like the LO-US bridge. A small board computer based solution I reviewed earlier. Currently costing about 175 euros excluding the power supply. At about 65 euros for the mid-quality power supplies I mentioned earlier. Then the Henry Audio DAC really starts to shine. Midrange opens up further as does the stereo image while symbols and strings sound more real and relaxed. For now there is a fair good power supply that is further cleaned by the yellow and a USB signal that is clocked with more precision. The U.S. bridge can run on a wide range of players and audio bridging programs as you can learn from the U.S. bridge review. This is a very good combo making fine music at a very good price. Even better sound quality was achieved when I connected the Henry Audio DAC to the SOtMS200 Ultra Neo network bridge. Now the stereo image is even more spacious at about 50% of that of my Brooklyn DAC with sibilance control and for instance symbols are at about 60% of the Brooklyn. But to be honest spending over 1700 euros on a bridge and then only spend 300 euros on a DAC isn't a well balanced investment. I just mentioned it to make my point on clean digital sources. The Henry Audio USB DAC 128 Mark III has practical limitations like only one input being USB, no DSD or MQA and no external volume control. But these things are clear up front and to be honest unless you really own a lot of DSD music I wouldn't lose any sleep over it. DSD is great but the choice of music is rather limited and certainly doesn't offer many popular albums. MQA is more difficult since currently only title is streaming MQA. So again an easy choice as are the other facts. If you can live with these it is a DAC that offers a sound quality that can grow with you. Ask Santa for a DAC for Christmas and start playing from your computer. Then later on tweak it with a network bridge and a power supply in easy affordable steps. In the end you might have spent less than when you would have bought an about equally performing streamer and you spend it in steps. If you are handy with the soldering iron you might go another route that might bring you to the same or better results for less. But I won't cancel you when problems arise.
