FOR SALE: Fully Restored Pioneer A-88X Integrated Amplifier – Reference Class Power & Precision
Up for sale is a stunning, bench-restored example of Pioneer’s mid-80s reference engineering: the Pioneer A-88X. Delivering a conservatively rated 120WPC into 8 ohms with virtually imperceptible distortion (0.003% THD), this beast combines raw current delivery with ultra-refined, dual-mono imaging.
Fitted with handcrafted custom real-wood walnut side panels, it sports the timeless, high-end "Elite" aesthetic to match its stellar sonic performance.
