Integrated amplifiers — Luxman L-507uXII

The L-507uXII is an integrated amplifier with phono stage from Luxman, sitting above the L-505uXII with considerably greater output power. The L-507uXII brings Luxman's more accomplished current engineering to a complete 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, matching the L-505uXII. Input impedance is 55,000 ohms balanced or 47,000 ohms single-ended, also matching. The phono stage uses the same sophisticated current-sensing design. Output power is 110W into 8 ohms, rising to 210W into 4 ohms - considerably more than the L-505uXII's 100W/150W. Signal-to-noise ratio is 105dB, with total harmonic distortion plus noise at 0.08%. Damping factor is an exceptional 260. At 440 x 178 x 454mm and 25kg, the L-507uXII shares its chassis dimensions with the L-505uXII while offering considerably greater power.

Sound and use context

Expect the accurate, refined character Luxman's broader considered engineering philosophy is celebrated for, with the considerably greater 210W-into-4-ohms output providing more headroom than the L-505uXII.

Pairing

The current-sensing phono stage handles both moving-magnet and moving-coil cartridges directly without needing a separate step-up transformer.

Alternatives

Luxman's own L-509Z Black Edition CENTENNIAL offers Luxman's absolute current flagship alternative within the same broader L-series catalogue.
