Notes

• The Luxman L-570Z's is another update of the L-570 and was only available in Japan. Customer feedback indicated that the L-570's sound was too soft for many, and they expected more of a dynamic sound along the lines of the L-540. Accordingly, the L-570Z's power supply was designed to be more dynamic, and various circuits were better designed to avoid attenuating dynamic and phase shifts. In addition, the L-570X's partially redesigned circuit boards were further optimized, gold-plated & nitrogen-filled sealed relays were used, the chassis as well as the preamplifier power supply was reinforced, heat dissipation was now done with pure copper heat pipes, and the entire interior was rewired with pure copper cables.
• Visually, the Luxman L-570Z's was identical to its two predecessors. However, new (this as a visual differentiation) the monitor button was now designed in red.

• Other models of the same series:
  • L-540
  • L-570
  • L-570X
  • L-570Z's
