Offered is „Aquarius EV03 Silber Stromreiniger“ by IsoTek Power Systems Ltd. as second-hand device from the category „Power supplies / power supply“ on audio-markt.de - the online market place for high-end. The advert with the number 9724414340 ends on 10.11.2026 at 17:14 o'clock.
At €990, this sits a bit under the €1,135 median and well above the €613 25th percentile, so it reads as a solid fair buy rather than a bargain or an ambitious ask. For a well-known mains conditioner, that’s a sensible place to land if the unit is clean and working as intended.
The appeal here is straightforward: IsoTek’s Aquarius is respected for lowering hash and tightening the presentation without turning the sound thin or overcooked, especially in systems that already reveal mains noise. If it’s complete, unmodified, and from careful ownership, this is the kind of piece that can quietly improve a whole setup and hold its value reasonably well.
Independent perspective — not a price guarantee. Always verify condition, accessories and provenance before purchase.
