Differences Between QA390mod and QA390LE

  • Same Circuit and Materials:

    • Dual AS338 global clocks.

    • ES9038PRO DAC chip.

    • LDAC high-definition Bluetooth input comparable to local playback.

    • Same optimized power and analog circuit as QA390LE.

  • Production Process: QA390mod uses a mass-production process rather than the limited production process of QA390LE.

  • Appearance: QA390mod does not have the limited edition numbered nameplate.

  • Sound Quality: QA390mod sounds very close to QA390LE, with only subtle differences in smoothness. Overall similarity exceeds 95% (most audiophiles may not notice the difference).

How to Distinguish QA390mod from Regular QA390

  • "MOD" printed on the bottom right of the glass lens.

  • "MOD by Quloos" sticker on the left side of the machine.

  • Uses the same ES9038PRO version PCB board as QA390LE, with a rose-red DC input socket.
