Offered is „Aquarius EVO 3“ by IsoTek Power Systems Ltd. as second-hand device from the category „Line Filter“ on audio-markt.de - the online market place for high-end. The advert with the number 9072038442 ends on 26.10.2026 at 12:23 o'clock.
This is a buyer’s market for this category: at €650, this sits clearly below the €695 25th percentile and well under the €848 median, so it reads as a strong deal rather than merely fair. For a quality power distribution piece from a respected hi-fi brand, that’s the sweet spot where the value starts to look genuinely attractive.
Aquarius units are well-liked for giving a system a cleaner, more composed presentation without sounding flashy, especially in revealing setups where noise floor and separation matter. At this price, a clean example is worth moving on quickly if it includes the original box and any stock leads or paperwork; the main upside here is simply getting a well-regarded component at a genuinely friendly entry point.
Independent perspective — not a price guarantee. Always verify condition, accessories and provenance before purchase.
