Up for sale is a complete powerhouse set of 4 x PrimaLuna KT88 vacuum tubes, perfect for anyone looking to re-tube a heavy-hitting power amplifier or integrated amp (such as the PrimaLuna EVO series). This package includes a matched quad (4 tubes) that have seen very little action and are barely ...
This is a strong deal at A$280. Your comparable listings put the broader median at A$2,948, with the 25th percentile at A$1,135, though that dataset may include complete PrimaLuna equipment rather than valves alone. For a matched eight-tube set with two additional spares, the ask looks especially attractive if the advertised low-hours, excellent condition is accurate.
PrimaLuna Silver Label KT88s are a sensible replacement for compatible PrimaLuna amplifiers, offering the convenience of the brand’s selected stock and straightforward compatibility with KT88-capable designs. The real value here is the matched octet plus backup tubes, rather than merely the logo. Before paying, confirm the exact tube count, matching/test results, and that all ten valves are included; output tubes are consumables, so documented hours and trustworthy testing matter more than cosmetic appearance.
Independent perspective — not a price guarantee. Always verify condition, accessories and provenance before purchase.
PrimaLuna, a boutique Dutch hi-fi brand, emerged in 2003 from the vision of Herman van den Dungen, a seasoned industry veteran with over 40 years of experience. Born in the Netherlands, van den Dungen had built his reputation earlier through Durob Audio, founded in 1975 as one of the first high-end importers in the Benelux region. Drawing on decades of tinkering with vintage radios and turntables, he launched PrimaLuna to democratize elite tube amplification, blending European design ingenuity with rigorous quality oversight in Chinese manufacturing.
The brand specializes exclusively in vacuum tube amplifiers, including integrated, power, and preamplifier models across series like ProLogue, DiaLogue, and EVO. PrimaLuna's hallmark is its unique construction—point-to-point wiring, custom transformers, and tube rectification—prioritizing sonic purity, longevity, and minimal servicing needs over broader categories like speakers, DACs, or turntables.
Positioned as high-end yet accessible, PrimaLuna occupies a niche among tube enthusiasts, earning acclaim for delivering "joyous cost-value surprises" through reliable, musically engaging performance that rivals pricier competitors. Its reputation for dependability and superb sound has solidified its status among discerning audiophiles worldwide, underscoring Dutch precision in a crowded market.
