So, we revised the design using the same principles as Nimitra to make affordable ones without losing its principles. In highend audio, the most important part is to make timbre and PRaT done right to make music both enjoyable and believable. We use the best parts for highend audio performance. My wife literally cried hearing Eva Cassidy singing Fields of Gold.īefore designing Nikola PSU, we built a few prototypes with best possible sound quality.
Positive Feedback Writers’ Choice Award 2017 for Fidelizer Nikola Linear Power SupplyĪlthough others did not hear a difference with the accessory Nikola linear power supply I and my wife found the Nikola to add a bit of emotional content, in particular I believe the lower midrange is a bit sweeter, perhaps more relaxed when playing HQPlayer transcoded files. This list is culled from every piece of gear that we’ve reviewed each year and represents those components that stand apart in their ability to deliver a musically satisfying experience. During development, some customers who thought $300 power supply being too expensive ended up buying one of the very expensive prototype unit instead.ĪudioStream’s Greatest Bits Award, 2017 for Fidelizer NikolaĪudioStream’s Greatest Bits is our version of Recommended Components. We compared with highend CD/SACD transports such as Esoteric/dCS/Emm Labs to make sure we didn’t miss important information from reference sources.īefore launching Nikola, we have many Esoteric and dCS owners who are satisfied with our prototypes. We tested Nikola and early prototypes in many highend systems as computer audio server’s power supply. It’s important to make sure the product will be safe and reliable for years to come. We also considered other design implementations like shunt regulator design but it tends to be very hot easily so we didn’t try it with over 3A cases. Focus became blurred and timing got a lot slower with strong sound signature from capacitor. No matter what capacitor brands and values we tried, it does harm more than good in our case. The reason why we dropped this design is mainly about sonic performance. I could vaguely guess already as I saw from products trying this approach before but we decided to try this too. You won’t get current shortage with this design but since we never has issue with current load, we decided to drop it like before.
LINEAR DC POWER SUPPLY FOR MAC MINI FULL
With very clean sound and precise imaging using choke-filtered, there’s also side effects of choke-filtered making the sound losing sweet touches and full body dynamics on lower frequencies so we shot this down. We also tried choke-filtered design too since some of preamps I like use this design. We decided to build transformer with specific voltage output for the best results with purist design approach. We also found side effects from two-stage voltage regulation with more heat dissipation from lost energy during each stage. It produced cleaner sound with smooth presentation but dynamics wasn’t as solid as before and worsened transient attack.
When we tried to to make early prototyping PSUs having cleaner sound, we also tried two-stage voltage regulation topology (not cheap transformer coil). Diode won’t work twice harder as before, DC current is even cleaner with matching design for non-balanced DC power output. So, we decided to use bridge rectifier with isolation transformer and the result is very satisfying. We tried building balanced AC power conditioner with full wave transformer but it didn’t work well as we hoped with increased noise from another phase. It should only be used with balanced DC power supply output only. Most devices accept single phase DC input so it’s not possible to make balanced DC output. We tried many ideas and here’s our reasons why we refused to implement these popular designs: We designed and built a few prototypes with many revisions through years with various devices including other servers, D/A devices, and even turntables. Thoroughly designed and tested for all products
