 Althans wat ik weet van alles, ben ik nog steeds aan het leren van de dag. Audio moet op basis van de signaal zijn, een signifieke deel zou willen worden geïnteresseerd als een kracht. En dat is allemaal over de voeding. Laten we jullie een paar van deze voedingen geven. Ik heb netwoordig netwoordige spelers in 2003 geïnteresseerd, al 15 jaar geleden. Er waren twee redenen om te worden geïnteresseerd. Mijn zon gebruikt zijn computer om muziek te spelen over een oud, maar nog heel goed geluid. Muziek van Fidelity A100 en B&S loudspeakers. De Marantz CD-player, met upgrade clock oscillator, was niet gebruikt. Toen was het eenvoudig. Hij gedeelte de MP3's met zijn vriend. Ik zag de mogelijkheden van audio en wilde het niet. De tweede reden was de marktintroductie van de eerste squeezebox. Slimdevices had al twee jaar geleden de Slimplayer geïnteresseerd, maar dat geluidde niet. Overigens had ik drie squeezeboxen, de eerste model, de duet en de touch. In dat tijd ontdekte ik de invloed van een goede voeding. Het was ook de eerste keer dat ik door de SBoost de beste tweede voeding van een tweede voeding kwam. Ik heb het nog steeds genoemd. Over de jaren ben ik geïnteresseerd met veel manier om audio files te spelen. Zoals van een Mac Mini met een plethora van spelers. Initiatie, iTunes met veel perfecte bedrijven. Dan zijn er zelfs bepaalde spelers zoals Amara, Ivana, J River, Pure Music en andere. De DAC was dan de fantastische Quart QDB76 HDSD. En voor een lange tijd dacht ik dat het de beste voeding met file-based audio was. Uitleid voor mij. Ik reageerde de Meridian Sulus Control 15 en de MediaCore 200 netwerkplayers. En ik was rather impressief. Ze zijn fantastisch over mijn Core DAC en de userinterface was van een andere wereld. Maar zo zijn de prijzen, de inability om mijn 500 dsd-albums te spelen en de limitatie over relatief kleine hardisken. Het was alleen 3 jaar geleden dat de Dutch distributier van Meridian mij in de richting van Roonlabs voldoende van de mensen die de Sulus software opgekomen hebben. Ik heb een licentie gehad en was voldoende. En op hetzelfde tijd heeft de Sonora MicroRendu Network Bridge de markt gehouden en het bracht een nieuwe dimension in file-based audio. De Mac Mini kon als een RoonCore server plaatsen while the MicroRendu functioned as a very clean USB output for Roon, close to the DAC. Of course, with the SBooster BOTW PMP power supply. If I remember well, the Core Jugo was the DAC at that time. Not so much later, SOtM introduced the SMS 200, that was functionally the same as the MicroRendu, sounded even slightly better and costed less. And they have an international distribution system. When SOtM introduced the SMS 200 Ultra only a year later, the next big jump was made in playback of audio files. Together with the Mitake Brooklyn and MQA, the audio result was so much better than, say, 3 years before. My well-maintained and modified more than 10-years-old audio note Soro SE en de AudioPhysics Scorpio loudspeakers, appeared to be able to sound so much better. It motivated me to replace the old Kimber loudspeaker cable by AudioQuest CastleRock, which again brought more sound improvement. The SBooster power supplies on the Brooklyn DAC and the SOtM network bridge got replaced by the MK2 versions and again the quality was a notch up. Recently the SBooster on the Brooklyn was replaced by the Syntax power supply and yes, that again brought further improvement. See my reviews for more details. The links are in the comments and at the end of this video. The first I learned in an early stage was the importance of a good power supply. But what is a good power supply? Of course it has to have very low noise. Properly controlled constant voltage en sufficient amperage. Deze demands might vary between devices. For instance, the MiTech Brooklyn uses internal DC-DC converters that have a high demand for instant high current. Switch mode power supplies are better capable of delivering that, but usually are noisier than the linear power supplies. The Syntax linear power supply appears to be able to beat the internal switch mode power supply of the Brooklyn. Not needed for a network bridge, but ideal for the Brooklyn. The AcuFox switch, an improvement I forgot to mention earlier, sounds best with its own switch mode power supply. There appears to be no easy answers and the consumer can only judge by trial and error. That's why I moved somewhat ahead as an explorer. The most astonishing was the discovery of the immense influence de quality of the digital signal has on the sound quality. That initially did not make any sense. An asynchronous USB or Ethernet signal should, at first sight, not be sensitive to timing errors. But the influence is enormous. I am now convinced that the difference between good digital players and truly high end players has to do with the power supply, timing perfection in the digital domain and time smearing caused by the digital to analog conversion, especially the reconstruction filter. These things are, of course, interleven. A poor power supply will cause jitter due to voltage variations on the power rail. And jitter will cause the digital to analog conversion to perform a poor reconstruction of the signal. With CD players the mechanism will put a strain on the power supply and the idea of reading microscopic pits from a 200-500 RPM spinning and vibrating disk at a speed of 5 kilometers per hour, 3.5 miles per hour, is ridiculous. It's a miracle it works at all. But it does. Sort of. Good power supply and careful handling of digital and analog signals as I describe in my series Audio Hygiene brings you more quality. It's like with food. You should not only buy the best fresh ingredients but use good oil or butter to cook or bake in. Use a quality pan, cook or bake it the right time and let it rest after cooking in some cases. Even the presentation does affect the taste, I'm told. It is the chain, not the individual link that define the strength of a chain. If you only use one strong link the chain will snap at any place butter link but it will snap anyway. It's the same with stereo. It's great that you use a good power supply but if only one other component isn't of the same quality the return on investment will be small. Let alone replacing one poor component by a better one in a chain of poor components. That's what happens when people say they hear no difference. I'm no researcher nor developer. I am an audio journalist. I evaluate equipment by using it and only do basic measurements to check if there are basic faults in the design. Like car journalists review cars.
