NAT Audio Single single ended amplifier. 50W Class A, dual mono construction, zero global feedback design, dot matrix display, remote control on volume and inputs, automatic bias, relay attenuator. Just serviced with a matched pair of Voskhod 1984 OTK 6N1P-EV valves. Fantastic sound and in excellent condition, original crate. 60kgs in crate.ExDem.
Excellent condition at £3,550 makes this look like a strong bargain against the recent used-market anchor: it sits well below the £6,198 25th percentile and far under the £8,814 median. For a buyer, that usually means you’re paying for a quick, attractive entry rather than the usual premium this brand can command in the used market.
NAT Audio gear is generally well regarded for delivering a big, organic, tube-amp kind of presentation with strong musical flow and serious build quality, so the upside here is obvious if the unit is healthy. In excellent condition, the main appeal is getting into a premium, niche piece at a price that leaves room for tubes, servicing, or matching it properly in your system; just confirm it’s complete, quiet, and functioning as intended.
Independent perspective — not a price guarantee. Always verify condition, accessories and provenance before purchase.
NAT Audio, a boutique high-end audio brand from Serbia, has earned a devoted following among tube enthusiasts for its handcrafted electronics. Emerging in the early 21st century, the company embodies Eastern European precision in vacuum-tube design, with products often hailed as "giant killers" for outperforming far pricier competitors in audiophile forums. Though specifics on its founding year and principals remain elusive in mainstream records, NAT Audio's heritage lies in Serbia's niche tradition of innovative, small-batch amplification.
The brand focuses exclusively on premium tube and hybrid electronics, specializing in single-ended topology and pure Class A circuits that prioritize audio purity. Their lineup features standout amplifiers like the SE2SE 75W/channel 211 SET monoblocks, using rare NOS tubes such as 1948 GE 211s, alongside two-box preamplifiers like the Utopia, and precision phono stages. This emphasis on meticulous, point-to-point wiring and innovative tube implementations sets them apart from mass-produced gear.
Positioned as a niche boutique in the ultra-high-end market, NAT Audio commands respect from discerning buyers seeking emotional, lifelike sound over hype. Far from mid-tier or vintage revivalists, their Serbian-made wonders deliver SET magic at accessible prices, often replacing legendary setups in passionate collections. For the knowledgeable hi-fi buyer, NAT Audio represents uncompromised tradition fused with subtle innovation.
