How much improvement in sound quality will the UHA-3 provide over the headphone output of my portable MP3 player?
The answer is: it depends. On some setups, the improvement is subtle. On other setups, the difference can be quite drastic. The UHA-3 provides a high-impedance load to the headphone output of your MP3 player. For the most part, your MP3 player can drive a cleaner signal to this high-impedance load than it can to a headphone load. The more difficult job of driving the headphones is left to the UHA-3. Keep in mind that the sound quality from any headphone amplifier is only as good as the source material. In other words, don’t expect much improvement with low-bitrate MP3s. back to the top Can I use the UHA-3 as a preamplifier to an A/V receiver or amplifier? Yes. The UHA-3 can provide a 13 dBu signal into a high-impedance load, such as the line input to a receiver or amplifier. The UHA-3’s USB streaming capability is a great way to provide a low-noise interface between your computer and a stereo system. back to the top Isn’t USB power too noisy to supply the sensitive audio circuitry of a
