Kinergetic KBA 2 Preamp with PSU Excellent and boxed and working perfectly.
This is a buyer’s market for this kind of older preamp/PSU combo, and at £500 it sits well above the typical used asking level of £296 and also above the £424 75th percentile. That makes it an ambitious ask rather than a fair-market steal, even allowing for the excellent condition.
The appeal is real if you want a serious, well-regarded separate preamp with external power supply: these are valued for their quiet presentation, solid dynamics, and the extra authority a proper PSU can bring. In clean condition, with no missing leads or later-service surprises, it can still make sense for the right system, but at £500 the buyer should expect strong cosmetic and functional evidence to justify it.
Independent perspective — not a price guarantee. Always verify condition, accessories and provenance before purchase.
# Kinergetics
Kinergetics Research emerged in the early 1970s from a group originally formed to undertake engineering development work for aerospace and undersea exploration. The company pivoted toward high-end audio during the nascent CD era, establishing itself as a respected designer and manufacturer of audiophile-grade electronics. Under the leadership of chief designer Tony DiChiro, Kinergetics became known for thoughtful, technically accomplished product design that prioritized sonic performance.
The brand built its reputation primarily through digital playback components, producing some of the earliest well-regarded audiophile CD players in the 1980s and early 1990s. As the market evolved, Kinergetics expanded its portfolio to include power amplifiers, preamplifiers, subwoofers, and surround-sound processors. Their amplifiers, notably the class-A designed KBA series, earned respect among discerning listeners for their refined approach to amplification. The company eventually ceased manufacturing CD players to focus on other product categories.
Kinergetics occupied a distinctly high-end, boutique position within the audio market—a niche brand favored by enthusiasts who valued engineering rigor and sonic integrity over mass-market appeal. The company is no longer active, having folded in the early 1990s, though its vintage equipment remains sought after by collectors and audiophiles who recognize the quality of its design legacy. Original Kinergetics components command respect in the used market as examples of thoughtful, well-engineered high-end audio.
