Teac UD507B USB DAC Headphone Amplifier Preamp - Black

Looking for a high-performance DAC, headphone amp, and preamp all in one sleek unit? The Teac UD507B delivers exactly that—and then some. Built on the premium design foundation of TEAC’s 700 Series, this A4-sized beast brings high-end sound straight to your desktop, without eating up your space.
Next-Level Sound With TEAC’s Discrete DAC

Let’s talk about the magic behind the music. The Teac UD507B comes loaded with TEAC’s in-house “TRDD 5” discrete DAC, a direct descendent of the tech found in their flagship 701 series. What does that mean for you? Crystal-clear imaging, an open and spacious soundstage, and a musicality that makes every note hit just right. It's like hearing your favorite tracks for the first time—again.
Beefy Headphone Amp That Means Business
You know what’s frustrating? A headphone amp that just can’t keep up. That’s not a problem here. Thanks to the fully balanced dual monaural design and TEAC-HCLD2 high current line driver, the Teac UD507B pushes out 1,200mW + 1,200mW at 100 ohms (balanced). That’s power on par with dedicated headphone amps—and this one’s got a DAC baked in.
And guess what? You’re in control. With three adjustable gain settings (Low, Mid, High), you can tailor the output to suit your headphones perfectly, whether you’re rocking sensitive IEMs or power-hungry cans.
Versatile Preamp That Plays Well With Others

Connectivity? Nailed it. The Teac UD507B acts as a high-quality preamp, equipped with the TEAC-QVCS analog volume attenuator and that same powerful HCLD2 line buffer circuit. It doesn’t just sound good—it plays nice with pretty much everything.
Five digital inputs and two analog options (yep, both unbalanced and balanced) make this a true hub for your setup. Whether you're streaming high-res audio from your PC, plugging in your CD player, or lining up your analog gear, it’s all good.
All That Power, Packed Into a Compact Frame
Who says great sound has to come in giant boxes? TEAC’s design team pulled off something impressive here. They crammed the performance of their high-end 700 Series into a compact A4 footprint. It looks slick, feels premium, and fits just about anywhere—your desk, media station, or shelf.
