In the high-end audio industry, the different audiocomponents are commonly built as separate boxes one box for the phonoamplifier, another box for the digital to analog converter, a third box for thepreamplifier section and one or more separate boxes for the output stage. Therefore, one important concept behind the Aavik U-300 -Ufor Unity - was to unite state of the art functions and components into onesingle, compact, high performance unit. This new amplifier would allow you toenjoy high-end performance, without having to live with numerous, odd-sizedboxes and a forever-growing cable snake pit. With the Aavik U-300, you get oneunit that has it all. You do not just get an amplifier; you also get 3 analogline inputs, a truly unique performing phono RIAA section and a superb 24bit/192 kHz DAC. Another important reason why we chose U for Unity isbecause the Aavik U-300 is a joint project between the designer behind themultiple award-winning loudspeakers of Raidho Acoustics and the highperformance cables of Ansuz Acoustics, Michael Borresen, and some of the bestanalog and digital designers that the world has to offer. This ensures that theAavik U-300 is an integrated amplifier, which is in the top of its league! We feel that sound cannot be explained it should be heard.

PHONO/RIAA The Aavik U-300 RIAA section is based on a discreet, floating, balanced, ultra-low noise, bipolar input circuit. By nature, thetopology of a moving coil cartridge is a floating, balanced signal generator. We have kept this floating, balanced circuit topology throughout the phonostage. The floating input circuitry allows us to use ultra-low noise, bipolartransistors. By paralleling several transistor pairs, we have created adead-quiet input section. The Aavik U-300 phono stage has a 63 dB gain, and thecartridge loading is adjustable from 50 to 5k. The phono section of the Aavik U-300 will let you explorethe amazing details and musical depths of your vinyl collection! DAC The Aavik U-300 DAC section is designed around 5 digitalinputs, which all excel in performance. The DAC performs without any digitalsignature, which makes any music sound "analog". The digital circuitsare created with the best high frequency skills tools available and great carewas embedded in the PCB design. We made a lot of effort to ensure we have a100% equal treatment of the differential signals, with time-aligned, ultra-short, 4-layer PCB traces. The DACs circuits are fitted with ultra-lowjitter onboard clocks in order to minimize timing errors in thedigital-to-analog conversion. In the Aavik U-300 all DAC circuits are isolatedwith 13 onboard, separate low-noise, high-PSSR voltage regulators each feedingonly one stage of the signal handling. The USB input is galvanic isolated to avoid noise pollutionfrom the host. The digital signals from the 5 digital inputs are routed to anASRC, where they are resampled and re-clocked to 200 kHz/24 bit PCM, feedingcurrent output DAC chips. The current-to-voltage conversion is performed with adifferential floating topology with virtual GND. This isolates the signal pathfrom the potential GND noise and signal induced GND modulation. Line Stage / Volume Control The Aavik U-300 line stage uses a unique, inverted, virtualGND amplifier topology, which preserves the finest musical details on a dark, quiet, black background. The line stage gain can be adjusted between 3-6-12 dB. These adjustments give you the opportunity to adjust individual levels of allinputs on the Aavik U-300 amplifier. The volume control is realized with a resistor ladder (R2R)circuit in 80 1dB steps. Design The Aavik U-300 design is typical Scandinavian, with asimplistic functionality and a minimalistic look. The cover is made of anodizedaluminum, which gives it a stunning matte black finish. The only other colorsseen on the front panel of the Aavik U-300 are small LED lights, indicatingyour current volume/gain/source/cartridge settings and three silver buttons onthe top panel. Adjusting the Aavik U-300 settings is easy all settingsare controlled with the three buttons and a big rotating knob. Specification  Output               2 x 300 W/8, 2 x 600 W/4 Distortion
