U. What it stands for depends on the movie. If it's Das Boot, U is shorthand for Unterseeboot, so German for submarine. In fact there was a German U-380 submarine of 67m length and 2'800 horse power as built at Kiel's famous Howaldtswerke which I passed by tram going to school every day. But if you're watching the hifi channel, U-380 doesn't roam in stealth mode below your radar. It's above the surface as Aavik's newest integrated. It's clearly not been named by members of the iGeneration. They'd have gone with 380i. Lars Kristensen and Michael Børresen instead aimed at the unified and, I would add, universal amplifier. Ergo, U-380 the unity amplifier.

Before it's all men on deck for the tour, another abbreviation needs spelling out. Aavik is a contraction for bay of eels. The pigs stay in Cuba. The Limfjord is where Denmark's map has the castle of eels aka Aalborg. That's where the company is located. My visit has more details. Here the brand trinity of Ansuz, Aavik and Børresen design and build all that a hifi requires except for, at present, turntables, streamers and CD transports. But electronics, speakers, cables, equipment racks, power delivery and resonance control devices are all accounted for in-house: vertical integration writ large.

Aavik's first product unveiled at CES 2015. It was the compact U-300 with DAC, phono and 300 watts of switching power by Pascal [right and below].

Priced at a cool €25.5K, it continued the ascendancy of class D into the ultra high-end which firms like Bel Canto, Jeff Rowland, Theta and Mola Mola had begun. Dominated by an enormous multi-purpose controller—men do love their knobs—it was also fitted with elegant vertical-bore heat sinks à la BFA and Dan d'Agostino. Under the covers, copper rails said nej tak to the hysteresis effects of paramagnetic aluminium.

Whilst Aavik subsequently fleshed out their line with separates, added a highly efficient proprietary class A bipolar output stage not with sliding bias then an entire lower-priced 150 range, the U-300 was the product that put them on the map. When time came to elevate their portfolio to the next level, it was predestined. This model would be first to get the latest tech makeover. Already in the pipeline were the C-380 preamp with phono and PCM/DSD DAC [€37'500, €43'500 with dual phono stages], P-380 150wpc stereo amp [€49'500] and M-380 300-watt class A mono amps [€49'500/ea.].

Hello U-380. It premiered at RMAF 2019 for the USA, at Stuttgart's Süddeutsche Hifi Tage for Europe. Said launches coincided with the first showing of the Børresen Z-01 monitor. That's the 150 equivalent in their speaker catalogue or—if we trace its lineage back to Raidho where Michael Børresen started to design transducers—the first chapter in their own lower-priced 'Scansonic' range now that Dantax Radio own the Raidho and Scansonic brands.

Guts & glories of the U-300.

As the next photo from the Denver exhibit demonstrates, the U-380 drove a pair of Børresen 01 monitors in a large 1'682ft² room. Nothing else was required. The U-380 includes a built-in phono stage and either parallel PCM and DSD converters or a PCM DAC plus a second phono stage. There's also a pre-out to drive a subwoofer, headfi amp or to bi-amp loudspeakers. That resumé does make for a rather universal amplifier. Just add source, speakers and minimal cabling.

Whilst the U-380 looks like a U-300 because it shares the same chassis, its complete redesign inside means that the older unit cannot be upgraded/rebuilt into the new one.
