Amplifiers & DAC
- Product Details
The PHA-3 is a USB digital-to-analogue converter (DAC) and headphone amplifier that processes digital audio - including High-Resolution Audio - and creates a dramatically superior soundstage for enhanced listening. The PHA-3 can support up to 384kHz/32bit PCM and even Double DSD (5.6MHz) formats. Featuring DSEE HX, the PHA-3 can upscale compressed digital music by restoring the subtleties lost in compression. The result is rich sound, closer to the quality of High-Resolution Audio.
The PHA-3 offers mainstream 3.5mm unbalanced output connection, and even a balanced connection with left and right outputs to ensure authentic and even sound. The two audio channels, each with an independent ground wire, use an inverted phase signal to reduce unwanted noise that is picked up as the signal passes through the wire from source to amplifier. The result - superior sound, delivered with clarity. The PHA-3 also offers optical input connection to HDD and SACD players, supporting up to 192kHz/24bit PCM input.
