Offered is „RG 10 Mk4 HD Master“ by Symphonic Line as second-hand device from the category „Transistor-Fullamp“ on audio-markt.de - the online market place for high-end. The advert with the number 4824250580 ends on 20.10.2026 at 18:07 o'clock.
Good condition helps here, but at €5,000 this sits above the €4,616 75th percentile, so it reads as ambitious rather than a clear bargain. It is not wildly out of line for a premium Symphonic Line piece, but the ask is priced at the top end of the recent used market and wants strong justification from provenance or extras.
That said, these amplifiers are respected for their muscular drive, refinement, and “big system” control, which is exactly why clean examples still attract serious buyers. If it’s fully original, properly serviced, and comes with documentation or accessories, it can make sense for someone chasing this level of German high-end sound; otherwise, a buyer should expect some room to negotiate.
Independent perspective — not a price guarantee. Always verify condition, accessories and provenance before purchase.
Symphonic Line, a German high-end audio manufactory, traces its origins to the late 1970s and early 1980s in Duisburg, founded by pioneering engineer Rolf Gemein. Driven by his exceptional ear for music and relentless pursuit of sonic perfection, Gemein established the brand around 1979-1984 to create components that deliver an immersive musical illusion. Owner-operated to this day, it embodies a hands-on, artisanal heritage rooted in German precision engineering.
The brand specializes in a comprehensive lineup of true-to-source hi-fi components, handcrafted with premium parts for audiophile-grade performance. Offerings span CD players, analog turntables, integrated and power amplifiers, preamplifiers, loudspeakers, and essential cables optimized to unlock each device's potential. This full-system approach ensures seamless integration, prioritizing natural timbre and dynamic expression.
Positioned firmly in the elite high-end market, Symphonic Line earns acclaim among discerning listeners for its "liquid sound"—tube-like warmth fused with precise detail, explosive dynamics, and tonal accuracy. Praised by journalists and enthusiasts since its inception, it caters to boutique connoisseurs seeking uncompromising musicality over mass-market appeal, maintaining a niche yet revered status in global audiophile circles.
