Our Thoughts RADAR AI

At €6,990, this is a fair-to-good buy, sitting comfortably above the €5,056 median but well below the €13,838 75th percentile for comparable used examples. It is not a bargain by the database numbers—the €2,707 25th-percentile mark is the real bargain territory—but the price looks defensible for a clean, complete Magnetostat Reference.

The appeal is serious: NAT’s transformer-coupled, pure-triode Class A design uses military-grade 6S31B-R tubes, offers both RCA and XLR operation, and is known for an unusually open, dynamic and immediate presentation. The main practical checks are that the separate power supply, remote and original packaging are present, and that the tube complement is healthy; this is a very heavy unit, so safe shipping matters. With those boxes ticked, €6,990 is a solid enthusiast-level purchase rather than an inflated ask.

Independent perspective — not a price guarantee. Always verify condition, accessories and provenance before purchase.

About NAT Audio

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.
