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.

Available in black, red, and limited-edition titanium gray to match the QH1 headphone amplifier.
