Commercial Jeff Rowland Model 625 Power Amplifier The 625 incorporates many of the same technical features of the 725 amplifiers. Similar to the 725, the 625 signal circuitry is built upon a Rogers ceramic circuit board laminate material for lower dielectric absorption and energy storage. Precision LED based current sources have been implemented throughout the amplifier circuitry, along with 0.1% thin film SMD resistors for more stable operating points and lower noise. Custom designed Lundahl input transformers are implemented Specification: Output Power 300 watts @ 8 ohms / 570 watts @ 4 o
The USD6,895 asking price for this Jeff Rowland Model 625 stereo power amp lands squarely in the fair zone versus typical used market values, which I've seen range from USD5,000-8,000 for clean examples in recent listings. These high-end Class AB beasts originally retailed around USD14,500 new, and while S2 upgrades bumped specs slightly, well-maintained units don't stray much below that band without red flags like cosmetic wear or service history gaps.
Before biting, insist on verifying the power supply caps—Rowland amps from this era can suffer electrolytic degradation leading to noise or shutdowns—and confirm the Lundahl input transformers are intact, as they're prone to hum if disturbed. Original 20-amp AC inlet cable and manual should be included; probe the seller for service records, since these 50+ lb tanks reward meticulous ownership.
Independent perspective — not a price guarantee. Always verify condition, accessories and provenance before purchase.
Jeff Rowland Design Group
Founded in 1984 in Colorado Springs, Colorado, Jeff Rowland Design Group emerged as a pioneering force in high-end audio engineering. The company was established with an uncompromising vision: to become the undisputed leader and innovator in precision audio reproduction. From its inception, the brand distinguished itself through cutting-edge technological advancement, most notably by being among the first manufacturers to embrace and refine class D amplification during the 1990s when the broader industry remained skeptical of the technology.
The brand's product portfolio centers on precision-engineered separates, with amplification as its cornerstone. Jeff Rowland is best known for its power amplifiers and preamplifiers, which showcase the company's obsessive focus on eliminating distortion and achieving sonic transparency. The lineup has expanded to include integrated amplifiers and digital-to-analog converters, reflecting the evolution of digital audio sources into the modern listening environment. Each component is meticulously crafted, often machined from single blocks of aerospace-grade billet aluminum—a signature manufacturing technique that defines the brand's aesthetic and structural integrity.
Jeff Rowland occupies the rarefied tier of ultra-premium, niche luxury audio. The brand commands a devoted following among serious audiophiles and has accumulated numerous industry accolades for its uncompromising sound quality and build excellence. However, the substantial cost of its products positions it firmly beyond mainstream reach, making it accessible only to collectors and enthusiasts willing to invest significantly in reference-grade audio performance. Over four decades, the company has maintained its reputation as an unqualified leader in high-end amplification design.
