Offered is „ST 150“ by VTL tube amplifiers as second-hand device from the category „Tube-Poweramp“ on audio-markt.de - the online market place for high-end. The advert with the number 793413162 ends on 24.12.2026 at 17:18 o'clock.
New, the VTL ST-150 sits around €5,300, so €3,750 used is a fair asking price rather than a bargain. It lands exactly at the 75th percentile of five recent comparable listings, above the €2,946 median and well clear of the €2,281 lower quartile. I’d want the condition and valve history to justify that premium.
It remains a highly desirable power amplifier: the switchable tetrode/triode operation gives genuine flexibility, combining substantial drive with the richer, more relaxed presentation many tube enthusiasts value. Its 6550 output stage has individual bias adjustment per tube, and the generous power suits demanding loudspeakers. At this price, confirmation of healthy tubes, stable bias, correct EUR mains configuration, and included cages or original packaging would materially strengthen the case; otherwise, there is room to negotiate toward the median.
Independent perspective — not a price guarantee. Always verify condition, accessories and provenance before purchase.
Vacuum Tube Logic (VTL) traces its roots to the early 1980s, when recording engineer David Manley began designing high-fidelity vacuum tube amplifiers in South Africa, initially modifying Leak units. By 1983, the brand launched its first power amplifiers and preamplifiers under Vacuum Tube Logic in the UK for the European market. David and his son Luke introduced the products to the US at the 1986 Consumer Electronics Show, relocating production to Rhode Island and then Chino, California, as Vacuum Tube Logic of America. In 1993, Luke Manley founded VTL Amplifiers, Inc., independently, solidifying its American base in Chino, where all products are still handmade today.
VTL specializes in high-powered tube amplifiers and preamplifiers, emphasizing pure tube designs with simple circuit paths, robust power supplies, and premium output transformers for full-frequency response and minimal distortion. Their lineup focuses on delivering dynamic, musical sound reproduction, blending modern technology with user-friendly reliability. While not venturing into speakers, turntables, DACs, headphones, or cables, VTL's components excel in recreating live music's vitality in home audio systems.
Positioned firmly in the high-end hi-fi market, VTL commands a reputation for timeless, reliable tube gear that appeals to discerning audiophiles seeking emotional engagement over gimmicks. Led by Luke Manley, the brand marries musical purity with elegant design and proven longevity, earning acclaim as a leader in high-performance tube amplification for over four decades.
