Wyred 4 Sound


 Digital-to-Analog converter & Headphone amp

No matter how you choose to use the µDAC HD, you’ll be amazed how such a small package can deliver such a great sound. The building block is the the amazing Sabre DAC, a chip that’s derived from the same platform as the industry-standard ESS9018 found in our flagship DAC-2 series. The ESS patented Hyperstream™ and Time Domain Jitter Eliminator technology guarantees a jitter-free digital signal and remarkable sound from any source.

As a fully portable unit, the µDAC HD’s headphone stage allows for high-quality music reproduction when powered through your computer’s USB port. When plugged-in with the unit’s DC power converter, the µDAC HD automatically becomes a superior performing Class A headphone amp.

"[The µDAC-HD] caught me by surprise with its amazingly smooth, natural, and musical delivery. It doesn’t try to impress you with coloration but maintains its tonal integrity across all genres of music. I regret not auditioning this wonderful DAC/headphone amp earlier. Admittedly, I gravitated towards and spent most of my listening sessions with the Wyred 4 Sound uDAC-HD. It’s just a pleasure to listen to with no glaring faults.... I could listen to this DAC for hours and never get fatigued or overwhelmed. The other two have the tendency to do that after some time.... Very analog sounding, no artifacts, even in USB mode. Most liquid of any portable DAC I’ve ever used."
