Offered is „GURU LINE VORSTUFE – Gelegenheit !!“ by Tube Technology as second-hand device from the category „Pre-Amplifier / Processor“ on audio-markt.de - the online market place for high-end. The advert with the number 2576028364 ends on 19.12.2026 at 09:31 o'clock.
At €790, this is a strong deal: it sits exactly at the 25th-percentile mark and well below the €1,198 median for comparable used examples. It is the sort of price that deserves prompt attention if the unit is complete and functioning properly.
The GURU LINE is a serious, hand-built valve preamplifier, valued for its broad connectivity, separate tube power supply, and potentially excellent phono stage with MM/MC support. The line stage should appeal to listeners wanting a fluid, dimensional presentation without giving up flexibility, while XLR and RCA connections make system matching easier. Ask for clear photos of the valves, power supply, rear panel, and any included documentation, but at this price there is no reason to be reflexively cautious: a clean, working example looks like a genuine buying opportunity.
Independent perspective — not a price guarantee. Always verify condition, accessories and provenance before purchase.
Pro Audio Technology, known as PRO, traces its origins to 2004 when founder Paul Hales, a veteran of QSC Audio, established Professional Home Cinema, LLC in the United States. Hales aimed to bring genuine professional-grade audio into residential spaces, revolutionizing surround sound with loudspeakers and DSP amplifiers designed for high-end home theaters. In 2010, the company rebranded to Pro Audio Technology to align with its evolving strategic vision, while retaining its core focus on installed systems.
The brand specializes in professional-style loudspeakers and DSP amplifiers/processors tailored for residential custom installations. These components emphasize scalability, precision, and integration, often forming complete systems for immersive audio. PRO later expanded through its sister company, Theory Audio Design, adapting PRO technology for broader home audio applications without venturing into consumer categories like headphones, turntables, DACs, or cables.
PRO holds a niche boutique position in the high-end market, favored by A-list celebrities from the movie and music industries, sports figures, and global leaders for their private screening rooms. Its reputation rests on delivering pro-audio performance in domestic settings, prioritizing reliability and sound quality over mass-market appeal, making it a discreet choice for discerning buyers seeking uncompromising installed systems.
