Description
About this product:The original Yggdrasil with four AD5791 20-bit D/A converters remains in the line, because it provides an exceptionally engaging performance.Unique True Multibit™ PerformanceAll Yggdrasil+ versions use our True Multibit architecture, a unique combination of our proprietary time- and frequency-domain optimized digital filter and integrated, medical/defense grade multibit D/A converters. Yggdrasil’s DSP-based digital filter has a closed-form solution—it retains the original samples, performing a true interpolation. Only this digital filter gives you the best of both NOS and upsampling designs. Convenience and Flexibility, IncludedYggdrasil+ isn’t just about ultimate performance. At the same time, we’ve included 5 digital inputs, including our own Unison USB™ interface with complete electromagnetic and electrostatic isolation. Ease of access is assured with standard remote control, and we’ve provided features like absolute phase inversion and NOS mode so you can optimize for your individual system and recordings. Fully Modular Architecture—Ready for the FutureOnly Yggdrasil+ offers the flexibility and assurance of a truly modular architecture, both hardware and firmware. Literally every board—from input to output—is easily replaceable, with its uniquely reconfigurable chassis provides for future expandability. This unique upgradability gives you great performance now, and assurance for tomorrow. Designed and Built in California By “designed and built in California this is what we mean: the vast majority of the total production cost of Yggdrasil—chassis, boards, transformers, assembly, etc—goes to US companies manufacturing in the US. Our chassis are made minutes from our facility. Our PCBs are done just over the hill from us. Our transformers are also made in California. All of this comes together in our Valencia, California facility, where each Yggdrasil is assembled, tested, burned in for 3 days, and then listen-tested again.
