Audia Flight FLS 9
High-end Audia Flight stereo integrated amplifier, 150 W per channel, designed for demanding speakers and upgradeable with optional DAC, phono or additional input cards.
Description
The FLS 9 is a high-end stereo integrated amplifier from Audia Flight, belonging to the FLS series alongside the FLS1 and FLS10 models, with which it shares the same fully balanced preamplification circuits. It delivers 150 W into 8 ohms per channel, achieved through six selected transistors on each channel.
This configuration gives it the speed and control capability sought by the brand, making it suitable for driving low-efficiency speakers or those with a critical impedance, below 2 ohms. The power supply relies on a shielded, audio-grade toroidal transformer rated at 1000 W, which distributes current to eight very low impedance, very low noise secondary circuits, printed on thick copper layer boards. A set of high-quality capacitors totalling 120,000 µF completes this power supply to ensure a substantial energy reserve.
The solid aluminium chassis is machined, brushed and anodised, with the Audia Flight logo engraved on the cover; it is available in silver or black finish. Two external hatches on the rear panel provide easy access to the inside of the unit to install one or two optional cards from those available.
Several expansion cards can indeed be added depending on requirements:
This model is aimed at high-end electronics enthusiasts looking for an integrated amplifier capable of adapting to demanding speakers and evolving over time according to use, whether adding a digital source, a phono input or additional connections.

What to check before buying used
On these amplifiers with a large energy reserve, the motorised potentiometer deserves careful checking: look out for any crackling or channel imbalance at the end of its travel. The filtering capacitors, despite their generous capacity, lose performance over the years and with the number of charge cycles they have undergone. A look at the connectors on both rear hatches and at the condition of the chassis anodising also helps identify a unit that has travelled extensively or been handled carelessly.
