The Heritage Headphone Amplifier’s ESS Sabre32 D/A converter is amongst the best on the market, delivering top-quality 24-bit/192kHz digital audio. It also supports DSD. This audiophile-grade DAC boasts ESS 32-bit HyperStream DAC architecture and Time Domain Jitter Eliminator, ensuring that you experience crystal-clear sound with minimal distortion. Whether you listen through your favorite set of high-end headphones or through a pair of top-of-the-line powered speakers, you can be assured that you’re benefitting from the best sound quality possible. The Klipsch Heritage Headphone Amplifier’s dual Class AB TI TPA6120A2 amplifiers are a perfect match for its top-quality DAC. Their superior design not only minimizes crosstalk, it also increases the total system output to provide the best signal-to-noise ratio achievable. The Heritage Headphone Amplifier was tailor-made for audiophiles, boasting an XLR-4 balanced headphones output. And if you’re using standard headphones, a hi-Z switch gives you a +10dB boost for optimal sound quality. Armed with an XMOS asynchronous USB audio interface, the Heritage Headphone Amplifier locks incoming digital audio streams onto its internal clock to ensure ultra-clean reproduction. It works like a charm with any Windows 7- or 8-equipped PC, and ASIO support is included for compatible audio applications. When we ran the Heritage Headphone Amplifier through its paces here at Sweetwater, we tested it with both iOS and Android devices, and found it to be a significant upgrade over their built-in D/A — the difference was night and day. If you want to give your listening experience a serious sonic upgrade, this headphone amp is a smart way to go.
