Power amplifiers stereo — Audia Flight STRUMENTO n° 4

The STRUMENTO n° 4 is a formidable stereo power amplifier from Audia Flight, sharing the FLS8's exceptionally wide bandwidth philosophy within a two-channel format and staggering mass. The STRUMENTO n° 4 represents Audia Flight's most ambitious current statement in stereo power amplifier engineering.

Key specs that matter

Input sensitivity is 1,410mV, with input impedance at 7,500 ohms on both connections, matching the FLS8. Output power is a substantial 250W into 8 ohms, rising to 500W into 4 ohms. Gain is 29dBu, matching the FLS8. Frequency response spans an exceptionally wide 0.3Hz to 1,000,000Hz within plus-or-minus 3dB - even wider than the FLS8's 600,000Hz. Signal-to-noise ratio is 110dB, also matching. Damping factor exceeds an extraordinary 1,000 - considerably higher than the FLS8's 200. Maximum power consumption is a substantial 1,000W - a considerably more plausible figure for this output level. At 450 x 280 x 500mm and a staggering 103.5kg, the STRUMENTO n° 4 represents Audia Flight's absolute current flagship stereo power-amplifier engineering ambition.

Sound and use context

Expect extraordinary dynamic authority and control reflecting the extraordinary over-1,000 damping factor combined with the exceptionally wide 0.3Hz-1MHz bandwidth, representing Audia Flight's most accomplished current stereo power-amplifier engineering.

Pairing

The extraordinary over-1,000 damping factor combined with the substantial 500W-into-4-ohms output handles the most demanding loudspeaker loads.

Alternatives

Audia Flight's own FLS8 offers a monoblock alternative within the same broader catalogue for buyers preferring separate mono chassis.
