Offered is „V5 Aquarius - Schwarz/ 6-fach Filter“ by IsoTek Power Systems Ltd. as new device from the category „Power supplies / power supply“ on audio-markt.de - the online market place for high-end. The advert with the number 9507061839 ends on 13.11.2026 at 06:37 o'clock.
This is a buyer’s market for high-end power filters, but the €2,590 asking price for this IsoTek V5 Aquarius is ambitious, sitting just below the 75th percentile (€2,760) of recent EUR listings and well above the median (€842). While new European stock lists around €2,799, treating this as a “new” unit in a used category makes the price heavy unless the condition is truly pristine and unopened; for a used item, it’s overpriced compared to the typical market range where fair deals cluster near €842.
The V5 Aquarius remains a top-tier choice for serious systems, delivering six dedicated high-current Schuko outputs that eliminate network noise and stabilize power for amplifiers and sources. Its real upside here hinges on whether it’s genuinely new-in-box, original-owner, and includes all accessories—factors that could justify nearing the 75th percentile. If those hold, it’s a solid buy for a system demanding clean power; if condition or extras are unclear, aim closer to the €842 median.
Independent perspective — not a price guarantee. Always verify condition, accessories and provenance before purchase.
