Based 80km north of Rome in the port town of Civitavecchia, Audia Flight was formed in 1996 by
electronics industry veterans Massimiliano Marzi and Andrea Nardini. Currently available are
three integrated amps, two CD players, a preamp, a phono preamp, two stereo power amps and
a three-channel power amp. All Audia Flight components are designed and built in Italy and not
outsourced offshore. The piece reviewed today is from Audia Flight’s new entry level FL Three
line. Coming soon is a matching CD player and a pre/power combo. The FL Three integrated is a dual-mono design rated to deliver 75 watts per channel into an 8Ω
load.

Both channels are fed from a single 400VA toroidal transformer while a smaller 10VA toroid
feeds the relays and control logic. There are eight stabilized power supplies with a total
capacitance of 13,200uF, and another 72,000uF for the output stage. The volume control is an
ALPS blue and the muting function has its own memory. All switching logic is independent of the
analogue section through the use of opto-couplers. As with all of Audia’s amplifiers, the FL Three
uses current feedback instead of the more common voltage feedback.

According to Audia Flight, "…differential designs for amplification (voltage feedback) with quite
extended frequency response have the drawback of a transient instability or, anyway, when
excited with a step impulse, their output attains a steady state only after several extra oscillations
which clearly affect the original signal with colorations.
This new scheme exploits current feedback rather than the usual voltage feedback and the
amplification is of the transimpedance kind (and, therefore, extremely linear) with the feedback
closed before the output stage. The outcome consists of very fast, stable circuits with the utmost
ability to control even the wildest reactive loads."

The 15mm thick front panel, remote control, volume knob and feet are CNC machined from solid
aluminum. The two button input selector controls four unbalanced and one balanced input. There
is a tape monitor loop, pre out and headphone output. A bypass feature selectable by remote
control allows owners to turn their FL Three into a power amplifier through a specified input or as
the front-channel amplifier in a multi-channel system while still using the same speakers for two-channel
listening from stereo sources. Audia Flight offers an optional RIAA moving-coil/moving magnet
phono board. Input impedance is adjustable via card-mounted dip switches while specific
impedances can be set with plug-in resistors. I am not aware of any other plug-in phono boards
with this degree of flexibility. The manual offers a rather busy but easily understood chart to guide
you in setting proper loading for your cartridge. My loaner came preset for my Ortofon Rondo
Blue moving coil. Gain for moving magnet cartridges is 44dB while moving coil is 64dB.

On the rear panel, there are also two digital communication jacks to link other Audia Flight
components for synchronous power on/off switching as well as to distribute firmware upgrades.
The large VFD vacuum fluorescent display on the front panel provides current operational status.
The panel’s brightness is adjustable including turning it off altogether via the remote. The Audia
Flight logo at the far left will light up upon turn on or flash intermittently when in standby. The input
names displayed are custom programmable by remote with a maximum of seven characters. You
can imagine the childish fun I had with this feature.

The remote was one of the nicest I have used and I preferred its feel over the one that came with
my Audiomat amp. It was also the first I have seen that uses lithium batteries instead of the more
common, bulky, short-lived AA alkaline types.
