Integrated amplifiers — Luxman L-507Z

The L-507Z is an integrated amplifier with a built-in phono stage from Luxman, positioned above the L-505Z with more output and a higher damping factor. This model represents a genuine step up within Luxman's L-series integrated amplifier lineup, offering meaningfully more current delivery and connectivity refinement than the entry L-505Z.

Key specs that matter

Two balanced and four single-ended inputs plus phono are provided, one more balanced input than the L-505Z. Input impedance is 79,000 ohms balanced, notably higher than the L-505Z's 55,000 ohm figure. Output power is 110 W into 8 ohms, doubling to 220 W into 4 ohms - a clean doubling the L-505Z's more modest 100/150 W figures do not achieve. Signal-to-noise is 105 dB. Damping factor is 350, considerably higher than the L-505Z's 200. At 440 x 178 x 454 mm and 25.4 kg it is heavier than the L-505Z.

Sound and use context

Expect a more controlled, higher-output presentation than the L-505Z, with the clean doubling into 4 ohms and considerably higher damping factor suggesting a more capable power supply and output stage - buyers stepping up specifically from the L-505Z should find a meaningful improvement in current delivery and loudspeaker control.

Pairing

The clean doubling into 4 ohms suits demanding or low-sensitivity loudspeakers considerably better than the entry L-505Z, broadening the range of speakers this amplifier can comfortably serve.

Alternatives

The L-505Z sits below this model for a more accessible entry point; the L-509X sits above it with even more output and connectivity, worth the further step up if this model's already improved capability still leaves ambitions for Luxman's top L-series tier. A dealer demonstration comparing this model directly against both the entry L-505Z and flagship L-509X helps clarify exactly where this mid-tier model earns its keep within Luxman closely related L-series lineup. Given the considerable 25.4 kg weight, a solid, well-supported equipment shelf is worth confirming before installation. Overall this remains a capable mid-tier choice within Luxman closely related L-series catalogue. A dealer visit remains the simplest way to compare current pricing across the whole Luxman L-series lineup. Cable and stand choices matter far less at this price point than getting the basic source pairing right. Adequate ventilation space around the chassis also helps this amplifier run reliably over long listening sessions.
