DEQX Pre main 8 Pre Amplifier Selling my DEQX Pre-Main 8, a world-class digital preamplifier and correction processor known for its transparency, precision, and extraordinary room/speaker correction capabilities.

Condition is unknown, but at A$9,850 this is clearly above the typical used market for recent comparable AUD listings: well past the A$4,704 75th percentile and nearly 4x the A$2,620 median. That makes it an ambitious ask unless this is exceptionally complete, freshly serviced, or from a very high-end variant of the range.
That said, DEQX gear has a strong following for a reason: its speaker/room correction and digital preamp duties can bring real gains in focus, tonal balance, and integration, especially in revealing systems. If it’s fully functional, includes the right accessories, and has been kept carefully, there’s real upside here—but I’d want proof of software/license status, I/O compatibility, and service history before paying this sort of premium.
Independent perspective — not a price guarantee. Always verify condition, accessories and provenance before purchase.
