45 - 54Kg: 6 layers
*You can adjust the tension by the number of rings and arrangement.
Vibration in audio equipment is a serious problem that can't be ignored. If you remove it in any way you can improve
the sound more than you can imagine. It makes very firm, disctinct and deep bass level. Mid-range is very smooth
and detailed and no irritable and aggressiveness in high frequecy range. Clear, firm and wide sound stage mean that
it's getting close to the natural sound.
The Gyrotension Isolator is the ultimate resonance/vibration control device that employs the most precise and absolute
resonance/vibration absorbing, dissipating and eliminating function.
The Gyrotension Isolator is the most effective device for the vibration from the outside. One of them is "Ground-borne
vibration" and universally accepted as one of the major reason for the variability in the performance of audio equipment.
However tiny a vibration may seem to us, it will affect huge impact to the hi-fi audio signal processing systems.
You can set the optimum load by hooking the calculated number of rings. Recommended: 250g (0.55 lb)/each ring
3 Ceramic balls for 2nd vibration isolation.
You can adjust the height even under working load state by rotating the main body (written in 'VEGA').

看起來是跟丹麥Raidho有關，因為消息是Raidho所發佈的，Raidho以喇叭為主，所以Aavik Acoustics就以推出電子產品為主
U-300是一台綜合擴大機，具有24Bit/192kHz DAC與RIAA唱放功能，一台就解決所有的要求, U是Unity一件的意思，當然也有類比輸入 輸出為2 x 300 W/8Ω, 2 x 600 W/4Ω
In the high-end audio industry, the different audio components are commonly built as separate boxes: one box for the phono amplifier, another box for the digital to analog converter, a third box for the preamplifier section and one or more separate boxes for the output stage.Therefore, one important concept behind the Aavik U-300 -“U” for Unity - was to unite state of the art functions and components into one single, compact, high performance unit. This new amplifier would allow you to enjoy high-end performance, without having to live with numerous, odd-sized boxes and a forever-growing cable snake pit. With the Aavik U-300, you get one unit that has it all. You do not just get an amplifier; you also get 3 analog line inputs, a truly unique performing phono RIAA section and a superb 24 bit/192 kHz DAC.Another important reason why we chose “U” for “Unity” is because the Aavik U-300 is a joint project between the designer behind the multiple award-winning loudspeakers of Raidho Acoustics and the high performance cables of Ansuz Acoustics, Michael Borresen, and some of the best analog and digital designers that the world has to offer. This ensures that the Aavik U-300 is an integrated amplifier, which is in the top of its league!
DAC The Aavik U-300 DAC section is designed around 5 digital inputs, which all excel in performance. The DAC performs without any digital signature, which makes any music sound "analog". The digital circuits are created with the best high frequency skills tools available and great care was embedded in the PCB design. We made a lot of effort to ensure we have a 100% equal treatment of the differential signals, with time-aligned, ultra-short, 4-layer PCB traces. The DAC's circuits are fitted with ultra-low jitter onboard clocks in order to minimize timing errors in the digital-to-analog conversion. In the Aavik U-300 all DAC circuits are isolated with 13 onboard, separate low-noise, high-PSSR voltage regulators each feeding only one stage of the signal handling.
The USB input is galvanic isolated to avoid noise pollution from the host. The digital signals from the 5 digital inputs are routed to an ASRC, where they are resampled and re-clocked to 200 kHz/24 bit PCM, feeding current output DAC chips. The current-to-voltage conversion is performed with a differential floating topology with virtual GND. This isolates the signal path from the potential GND noise and signal induced GND modulation.
VR The Aavik U-300 line stage uses a unique, inverted, virtual GND 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 all inputs 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 a simplistic functionality and a minimalistic look. The cover is made of anodized aluminum, which gives it a stunning matte black finish. The only other colors seen on the front panel of the Aavik U-300 are small LED lights, indicating your current volume/gain/source/cartridge settings and three silver buttons on the top panel. Adjusting the Aavik U-300 settings is easy – all settings are controlled with the three buttons and a big rotating knob.
