Our Thoughts RADAR AI

At US$180, this sits a bit above the US$150 median for recent comparable listings, but still comfortably inside the normal used-market spread between US$92 and US$222. That makes it a reasonable, not bargain-bin ask: fair if it’s clean, tested, and ready to plug in, but not low enough to call a steal on price alone.

What makes it worth a look is the core appeal of these compact Niles amps: simple two-channel duty, automatic turn-on, and enough power for secondary rooms, outdoor zones, or a modest desktop/whole-house setup. If it’s been well cared for and includes the right power and hookup details, that adds real convenience. At this price, I’d mainly want confirmation it powers up quietly, switches reliably, and has no channel imbalance or noisy relays.

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

About Niles Audio

Niles Audio traces its origins to 1978, when it launched in Miami, Florida, as a pioneer in switching systems for audio retailers. From these humble beginnings, the company evolved into a cornerstone of custom home audio, earning its stripes as a founding member of CEDIA and building a legacy of installer-focused innovation over four decades. Acquired by Linear LLC in recent years, Niles continues to uphold its heritage while expanding under new ownership.

The brand specializes in comprehensive whole-home audio solutions, offering over 500 products that span architectural speakers, amplifiers, receivers, automation controls, and accessories for seamless integration. Its portfolio emphasizes multi-room distribution, home theater systems, outdoor landscape audio, and cutting-edge options like the nearly invisible Cynema Soundfield in-wall soundbar, all designed for custom integrators to deliver professional-grade performance across indoor and outdoor spaces.

Niles holds a strong mid-to-high-end position in the custom installation market, renowned among savvy homeowners and professionals for reliable, high-quality distributed audio that blends effortlessly into modern living. Far from a vintage collector's niche, it remains a go-to for discerning buyers seeking robust, integrator-friendly systems that prioritize exceptional entertainment without compromise.
