Matrix M-Stage HPA-3U+ Class A Headphone Amplifier and USB DAC (Ships in 3-4 weeks)
Matrix Audio have released the HPA-3U Plus (USB) 24bit/192kHz DSD DAC + Headphone Amplifier to their M-Stage product line
The M-STAGE HPA-3U + is a biggest evolution since the introduction of the M-Stage headphone amplifier series.
The HPA-3U+ has a new appearance and a new circuit design that results in radical improvement in audio performance.
Usability improvements include three gain level options to suit the different impedance and sensitivity of various headphones
The M-STAGE HPA-3U+ is the most stable XMOS U series USB controller on the new USB module and supports 24 bit/192kHz sample rate PCM signal playback, DOP mode DSD playback capacity and DSD ASIO Native playback.
The unit is also compatible with iOS and the most Android devices.
The M-STAGE HPA-3U+ has an excellent structural design to quickly dissipate the heat of power transistors via the shell. The driver stage uses the constant precision current source. This also ensures the stability of the unit.
The full symmetric circuit layout results in an isometric path for the audio output of the two channels. This parallel output effectively reduces the output impedance of the output stage and improves driving capability and extended dynamic range.
The M-STAGE HPA-3U + uses an Alps 27 series volume potentiometer, Wima and Nichicon audio grade capacitors, a Noratel toroidal transformer and precision non-inductive resistance.
Each carefully selected component ensures that the HPA-3U+ presents the perfect sound and also provides stabily and reliability
