Integrate? Separate?

With their maiden U-300 model, Aavik Acoustics from Denmark integrated a DAC, phonostage, preamp and amplifier in one chassis. That offered multi-tasking modernity at a high level. They still did the same for the €36'000 successor, the U-380 reviewed here a year ago. With true 2020 hindsight, they now bowed separates even for their entry level. The associated confession? "We've come to realize that a lot of high-end users have a hard time respecting build-in DACs and phonostages even if they're among the very best available. So we've taken the consequences to turn back to the more traditional way of building audio systems. But that's the only thing traditional about our new Aavik electronics."

As we'd expect from a crack team under Lars Kristensen and Michael Børresen who at Nordost invented the most audible upsell—their cable comparator demos became legendary at trade shows—this new range again has clearly defined tiers of good, better, best. All share the form factor shown above. All related models run the same core circuitry with identical published specs. The four component types break out into a 300wpc Pascal class-D integrated amplifier, an MC phonostage, today's PCM/DSD DAC and a streamer+app. The 180 stack represents the first tier. As the 280 group, the second tier adds more proven Ansuz noise traps like tesla coils and analog-dither tech. For example, the D-180 DAC has 36 x active tesla coils, 104 x PCB-based coils and 5 x dither circuits. For the D-280, those scale up to 72, 176 and 8 respectively. 

The D-580 makes them 108, 248 and 11. This also reflects as weights of 5.4kg, 5.6kg and 7.3kg. Further in the 580 squad, the HDF case gets titanium struts and a pure copper liner inside. So resonance control isn't exclusive to the Ansuz Darkz footers reviewed here nor their matching titanium rack; and hysteresis effects from the ubiquitous use of aluminium are minimized already in the entry-level 180 versions. Should you stack yours, mechanical grounding is built in. For today's digital cases, we get 32bit/192kHz and DSD128 sample rate support with THD sub 0.005%, 4.5Vrms out on RCA exclusively, Z-out of 100Ω, standby draw below 0.5W, idle draw of 50W and dimensions of 103 x 384 x 400m HxDxW.

If you didn't know, Børresen speakers reviewed here and here and here and Ansuz power distributors, cables and accessories reviewed here are the other two brands which make up the Audio Group Denmark previously Upper Level triumvirate in Aalborg. It's what my factory tour described in more detail last year. With regular contributor Dawid Grzyb having reviewed the I-280 integrated and me not doing phono or streamers, I'd focus on the DACs – all three of them. You can't upgrade one to another after the fact but dealers will credit a high trade-in should you move up. I'm told that if a component is in excellent shape and not too old, this can even mean its full original amount. The exact details are obviously between buyer and dealer but it is stated Aavik policy to safeguard client investments as much as possible. Safeguarding your signal with today's DACs is galvanically isolated USB and asynchronous sample-rate converter. That upsamples/reclocks all data to 24bit/200kHz PCM into current-output converters unless disabled. Also user selectable is slow/fast filtering. With all x80 components, XLR are MIA so it's RCA all the way.
