MAESTRO HPA1

AUDMA MAESTRO HPA1 is the first amplifier on the market 
featuring the special characteristics offered by the ELISA circuit. 

It is a mature device which responds to the most sophisticated needs of top Hi-Fi and Hi-End audiophiles
to take their listening experience to the next level:

Automatic voltage change
Dual mono power supply with custom-built audio transformers
AKM AK4490REQ DAC chip with VELVET SOUND™ technology
Nichicon electrolytic capacitors
Wima Red series audio capacitors
Alps Alpine motorized potentiometers
Alpha switches

The amplifier features two stereo analog inputs (unbalanced RCA and balanced XLR) and three digital inputs (RCA coaxial, TOSLINK optical and USB 2.0), ensuring maximum connection versatility to the most diverse audio sources, both vintage and modern.

The output can be connected to Hi-Fi systems, TVs or other amplifiers by means of the LINE XLR or RCA output, and to headphones using Pentaconn connectors, 6.3 mm jack (with mini jack series adapter) and XLR 4-pin.

The front panel of the AUDMA MAESTRO HPA1 is equipped with courtesy lights, which make it easy to use even in the dark. For optimal performance of the amplifier, the use of closed-back headphones is recommended.
