DEQX A250 Power Amplifier Pretty impressive Class D amp. Utilising NCore technology , it produces 250w x 2 in 4 ohm or 200w x 2 in 8 ohm. Retailing for just over $2k , this amp is pristine and half price. Very little use as a bonus!

This A$1,050 asking price is a strong bargain, sitting well below the 25th percentile of A$1,615 for used DEQX A250 amplifiers in Australia. With the median at A$1,912 and the 75th percentile at A$2,755, you are securing a unit for roughly 45% less than the typical market median, making this an exceptional deal for a like-new listing.
The DEQX A250 series is highly regarded for its ultra-low distortion (<0.0018%) and massive damping factor (>1000), delivering rock-solid control over demanding speakers whether used for bi-amping or full-range passive setups. Originally priced around A$1,800–A$2,000 new, finding one in like-new condition at this price offers significant upside, especially since DEQX amplifiers are built to last and rarely show age-related issues. This is a genuine buying opportunity for an enthusiast who values precision and power without the usual premium.
