Integrated amplifiers — Luxman L-590AXII

The L-590AXII is a distinctive Class A integrated amplifier from Luxman, sharing the L-series' sophisticated current-sensing phono stage with a modest power output typical of pure Class A operation. The L-590AXII brings Luxman's most storied engineering heritage to a substantial Class A integrated chassis.

Key specs that matter

Two balanced XLR inputs and four single-ended inputs plus a dedicated phono input are provided. Input sensitivity is 180mV, with input impedance at 55,000 ohms balanced or 47,000 ohms single-ended. The phono stage uses the same sophisticated current-sensing design found across the L-series. Output power is a modest 30W into 8 ohms, rising to 60W into 4 ohms - reflecting the inherent power limitations of pure Class A operation. Signal-to-noise ratio is 107dB, with total harmonic distortion plus noise at 0.02%. Damping factor is an exceptional 320. At 440 x 193 x 463mm and 28.4kg, the L-590AXII's considerable weight for its modest power output reflects the substantial heatsinking required for genuine Class A operation.

Sound and use context

Expect the exceptionally smooth, richly textured character pure Class A amplification is broadly celebrated for, combined with Luxman's characteristic considered, refined Japanese engineering philosophy.

Pairing

The modest 60W-into-4-ohms Class A output pairs best with notably efficient loudspeakers to achieve satisfying dynamic headroom, given the inherent power constraints of Class A operation.

Alternatives

Luxman's own L-595ASE offers a related Class A alternative with somewhat different measured characteristics within the same broader L-series catalogue.
