 Wyred4Sound µDAC-HD DAC / Headphone Amp 


"Vocals are beautiful, instrumentation clean and crisp especially the bass and piano, sound is musical, sounds like I'm in a recording studio where they're taping live." So says one of our customers who likes to use the uDAC HD as a headphone amp with his Sennheiser HD 650’s.


No matter how you choose to use the uDAC 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 uDAC 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 uDAC HD automatically becomes a superior performing Class A headphone amp.
