We have announced the FLS1 about three year ago but we have spent three years more to introduce the FLS1. It was crucial for Audia Flight team the experience made with the Strumento n.1 mk2 worldwide awarded preamplifier.


The FLS1 is an unrivalled preamplifier on his category where speed, driving capability and control ability are elements close to perfection. Also a true Headphone power amplifier using Audia Flight technology ensure to your headphone a perfect and relaxed music listening. The output power is 12Wrms on 8 ohm! So it is able to drive any kind of headphone with perfect control and high current. Also two sets of gain can be choosing.


FLS1 is full balance preamplifier with an high-end volume control in dual mono configuration (each channel is assembled on separate print board), XLR and RCA outputs, REC RCA (fix level) output, three RCA inputs, two XLR inputs. The FLS1 is powered by three toroidal transformers close into a metal shield, with very low noise power supplies.

All inputs can be activated or deactivated, the gain can be adjusted (+/- 6dB), all name inputs can be renamed.

The FLS1 is the perfect device to “bring” musical signal with the best precision, energy and speed (bandwidth more than 500KHz) from sources to your amplifier.

Full brushed aluminium chassis, engraved “Audia Flight” logo on top cover, one aluminium remote control brushed and anodized, OLED blue display are Hi-END details.

There is the possibility to install two optional cards, plug and play, so very easy to install.


Optional cards:

-MM/MC phono board with unbalanced inputs

-MM/MC phono board with balanced inputs

-RCA board (2 RCA additional inputs)

-DAC board. One asynchronous USB input (with Galvanic isolation) 32 bit 768KHz and DSD 5.6. Five digital inputs (one optical, one AES/EBU, two SPDIF, one for Audia Flight SACD transport).

 32bit, 192KHz (with Galvanic isolation). Upsampling 32bit 768KHz.
