​Closed-Form Digital Filter Preserves Original Samples
Most DACs simply use the stock digital filters embedded in their D/A converters. But even the most sophisticated ones, using their own digital filter algorithms, don’t have what Yggdrasil has—a digital filter with a true closed-form solution—meaning it retains all the original samples, as it performs a true interpolation. This digital filter gives you the best of both NOS (all original samples retained) and upsampling (easier filtering of out-of-band noise) designs—and it is only available on Yggdrasil.

21 Bits, No Guessing: Mission-Critical D/A Technology
When doctors are trying to diagnose whether you have gas or cancer from MRI results, or when the military is trying to ensure a missile hits an ammo dump and not a nunnery next door, or they don’t use “24 bit” or “32 bit” delta-sigma D/A converters. Instead, they rely on precision, 20-bit ladder DACs, like the Analog Devices AD5791. This allows them the bit-perfect precision they need for critical applications, rather than the guesswork of a delta-sigma. We chose this same critical technology for Yggdrasil, in a balanced configuration that increases effective resolution to 21 bits. Following these unique D/A converters are sophisticated discrete JFET buffers and summers.

Adapticlock and USB Gen 3: Advanced Input Optimization
Yggdrasil accepts up to 5 digital inputs and carefully manages them with our Adapticlock™ clock regeneration system. Adapticlock is the most sophisticated clock management system in the world. It assesses the quality of all inputs, measures their incoming center frequency and jitter, and automatically routes the input to the best possible clock regeneration system. Yggdrasil also features our all-new USB Gen 3 input module, for even better performance than the acclaimed Gen 2 USB input.

Made in USA
By “made in USA,” we mean made in USA. The vast majority of the total production cost of Yggdrasil—chassis, boards, transformers, assembly, etc—goes to US companies manufacturing in the US. Our board house is 20 minutes away from our office in Newhall. Our chassis guys are just over the hill in the Valley.
