Our Thoughts RADAR AI

At €795, the timing doesn’t really add a penalty here: this sits right on the median of recent comparable EUR listings, so it reads as a fair, market-level ask rather than a bargain or an overreach. It’s comfortably inside the normal spread too, well above the €543 lower quartile and far below the €1,505 upper quartile, which is exactly where a sensible used buy should land.

That makes it interesting for buyers who want the Audio Innovations house sound without chasing a collector premium. The DeJongsystems modification adds a bit of niche appeal, and if the work was done cleanly by a reputable tech, that can be a meaningful upside. The main thing to assess is execution: confirm what was modified, whether servicing is documented, and whether the amp is stable and quiet. At this price, a properly sorted example looks like a solid enthusiast buy.

Independent perspective — not a price guarantee. Always verify condition, accessories and provenance before purchase.

About Audio Innovations

Audio Innovations emerged in 1984 from Brighton, England, founded by Peter Qvortrup and Erik Andersson with a mission to democratize valve amplification. Their debut offerings, the 800 Series power amplifier and matching preamplifier, embodied a commitment to affordable high-quality tube gear, aiming to place one in every home. This British heritage rooted the brand in the valve revival of the 1980s, blending craftsmanship with accessibility.

The company focused primarily on valve amplifiers, expanding into preamplifiers, kits, and even a transistor model with a quasi-complementary output stage. While not diversifying into speakers, turntables, DACs, headphones, or cables, their core strength lay in robust, user-friendly tube designs that prioritized musicality over extravagance.

Audio Innovations held a solid mid-tier position in the high-end hi-fi market during its active years, earning praise for reliable, value-driven valve amps among enthusiasts. Acquired by Audio Components in 1991 and later by Audio Partnership in 1996, the brand shifted toward budget lifestyle systems sold via UK retailer Richer Sounds, diluting its original prestige. Today, it survives more as a vintage collector's item than a current contender.
