Integrated amplifiers — Luxman L-505uXII

The L-505uXII is an integrated amplifier with phono stage from Luxman, built with a sophisticated current-sensing phono design and substantial output power. The L-505uXII brings Luxman's considered engineering to a complete integrated chassis.

Key specs that matter

One balanced XLR input 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 a sophisticated current-sensing design covering both MM at 47,000 ohms and MC at 100 ohms input impedance. Output power is 100W into 8 ohms, rising to 150W into 4 ohms. Signal-to-noise ratio is 104dB, with total harmonic distortion plus noise at 0.09%. Damping factor is an exceptional 210. At 440 x 178 x 454mm and 22.5kg, the L-505uXII maintains a substantial integrated amplifier chassis.

Sound and use context

Expect the accurate, refined character Luxman's broader considered engineering philosophy is celebrated for, with the sophisticated current-sensing phono stage handling both moving-magnet and moving-coil cartridges without a separate step-up device.

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-507uXII offers a considerably more powerful alternative within the same broader L-series catalogue.
