AGD ANDANTE Preamplifier

Design Philosophy

The AGD Andante is the perfect companion for the Vivace or The Audion GaNTube Monoblocks. Crafted with the same care and dedication as all AGD products, the Andante is a superior musical preamplifier that combines all the best of the analog and the digital technology available today.

The AGD Andante is a fully balanced analog design with four analog inputs and three analog outputs. The phono stage input is configurable for MC or MM cartridges. All analog circuits are fully shielded and separated from Digital Boards. A set of dedicated ultra-low noise LDO supply stage and high-dynamic low noise professional grade instrumentation amplifiers complete the output buffer stage.

The volume control is completely passive, with high precision resistors in a 256 steps ladder attenuator configuration. The Andante has full HD Streaming Capability (DLNA, UPNP, AirPlay, ROON) via Ethernet port, and has full AptX-Bluetooth compliance functionality.

With a state of the art USB module, based on the latest XMOS chipset that can decode any audio format available today (from MP3 to DSD512), and its professional grade 32bit-384kHz R2R DAC with DSP functions, the AGD “ANDANTE” is a complete audiophile Analog and Digital Reference Preamplifier that delivers unique set of features capable to meet the utmost musical standards of any demanding audiophile.
