Decware SE84UFO Integrated Amplifier (Valve) Hi, For your consideration is a less than one year old 2.3w EL84 based Decware Zen SE84UFO. As you may know there is a wait list of over 3 years for these amps from the factory. Skip the wait and pickup one in mint condition. Also included is the “one year club” T-shirt, stock tubes, a brand new matched pair of Genalex Gold Lion N709 EL84 and a matched pair of Tung Sol 7189 with roughly 10 hours. Happy to post as I have all the original packaging as it was posted from the USA. The professionals say it better than I. A few reviews below.
Are you paying for a genuinely special low-power amp, or just a small tube amp with a cult name? At A$2,100, this looks fair to slightly on the rich side rather than a bargain: Decware’s factory-direct SE84UFO is A$1,195 new before shipping, so the used price is only sensible if local availability, condition, and tube set are strong enough to justify the premium.
The upside is real if your speakers are a good match: this is a pure Class A single-ended triode design with a very simple signal path, a low-noise reputation, and the kind of transparent, immediate presentation Decware is known for. It’s especially appealing if the amp is clean, includes good tubes, and comes from an original owner with the right accessories, but do make sure your speakers are efficient enough and that there’s no hum, wear, or missing bits to explain why it isn’t closer to the usual used discount.
Independent perspective — not a price guarantee. Always verify condition, accessories and provenance before purchase.
# DECWARE
DECWARE, a trademark of High Fidelity Engineering, was founded in the mid-1990s by Steve Deckert in East Peoria, Illinois. The company emerged as a pioneering force in the low-powered vacuum tube amplifier movement in the United States, introducing the iconic Zen Triode amplifier in 1996—a remarkably simple 2.3-watt single-ended triode design that has since sold over 6,000 units across seven revisions. This foundational product established Deckert's philosophy of elegant minimalism and point-to-point hand-wired construction.
DECWARE specializes in tube amplifiers and loudspeakers manufactured entirely in the USA. The product line centers on integrated amplifiers, with the current flagship being the SE84UFO, a class-A zero-feedback design featuring an exceptionally minimal signal path. The company also produces complementary speaker systems designed to pair with their low-wattage amplifiers. All products are hand-assembled and built to exacting standards using premium components.
Positioned as a boutique, high-end manufacturer, DECWARE commands respect among discerning audiophiles and SET (single-ended triode) enthusiasts worldwide, with products distributed to over 54 countries. The brand is known for direct-to-consumer sales, lifetime warranties, and a 30-day return policy. DECWARE occupies a niche segment where affordability meets uncompromising sonic philosophy—accessible entry points into tube audio without sacrificing design integrity or build quality.
