Aavik I-880 - Den ultimative klasse-A forstærker
Med I-880 har Aavik udvidet deres udvalg af forstærkere med deres mest innovative og sofistikerede forstærkerproduktion til dato. Det primære udviklingsmål for I-880 var at skabe en kraftfuld ikke-switchende ren klasse A-forstærker med den lavest mulige udgangsimpedans, der ville bidrage til et bedre signal og mindre støj, og dermed forbedre højttalerens ydeevne. Alt sammen med henblik på at få en en meget mere organisk lyd og mere musikalitet. Det er i den grad lykkedes.
Den nye I-880 har en revolutionerende klasse-A forstærker, der kan leverer hele 2x200 watt i 8 ohm. Hele forstærkerens kredsløb er blevet designet, så signalvejen er så kort som mulig, og støjen derfor bliver på et absolut minimum. Det innovative Aavik-design er i solid kobber og med sine effektive køleplader bliver I-880 forstærkeren ikke så varme, som konventionelle forstærkere, hvilket resulterer i en højere effektivitet.
Samtidig udnytter Aavik de seneste teknologier fra Ansuz, som er med til at sikre I-880 soniske egenskaber. Teknologierne som Tesla Coils, Aktive Tesla Coils og den 3. generations Dither er med til at skabe et lydbillede, der er utrolig holografisk, naturligt og krystalklart. Hvert en tone kan lokaliseres med millimeter præcision, og den formidler storheden, detaljerigdommen og alt det følsomme med en imponerende overbevisning. Hvis du er på udkig efter den ultimative lytteoplevelse, så bør du overveje I-880. Kontakt os enten for en demo i butikken eller hjemme hos dig selv.
Technologies and Components
Through a long and intensive research and development process, Aavik’s engineering team identified several characteristic elements in the traditional Class A amplifier design that could be improved, which has had a very positive effect on the soundstage and musicality.
To create the best and most effective control section, Aavik’s engineering department has carefully tested and evaluated each electronic component to ensure both the lowest possible noise floor and further refinement of the signal. The ultimate goal of this thorough approach is for the amplifier to unlock a dynamic musical range that projects even the smallest musical details onto a palpably larger soundstage with an extremely quiet background.
Aavik 200W pure class A amplifier
Aavik have designed a circuitry that constantly keeps the bias spread 0,63 V above the required current, no matter where it is in the cycle. So, no matter how much current the power amp requires to perform, it always stays in Class A up to an impressive 2×200 W into 8 ohms, while at the same time not consuming unnecessary power.
This significant reduction in the power requirements of the amplifier allowed Aavik to design the capacitors as smaller units and place them locally, so that essentially each of the eight pairs of output transistors has its own capacitor bank right next to it. This means that the current does not have to flow through long wire harnesses and long circuit boards. The current is always directly at the output transistor, which means a shorter signal path and therefore less noise. In addition, this innovative Aavik design also means that the 880 amplifiers do not get as hot as conventional Class A amplifiers, resulting in higher efficiency.
Resonant mode power supply
This Aavik series is designed to ensure massive power resources with ultra-low noise. Unlike the square waves used by conventional switch mode power supplies, this Aavik series boast a resonant mode design which is principally driven by sine waves.
When more power is needed, the operating frequency increases, which, in turn, has the advantage that the power density also increases, thus allowing higher peak power when required by the music.
The noise floor in the raw power supply is extremely low but could be even further lowered by the ultra-low noise regulators supplying the different parts of the circuit. The noise of these regulators is measured in a few microvolts respectively nanovolts, which is significantly lower than the noise level of conventional regulators.
The principle of a traditional class A power supply is to create switching noise. This happens when the large capacitors have to absorb current from the transformer. Current can only flow into the capacitors when the voltage on the outside is less, so when current is needed, the voltage across the capacitors will be lower than the 50/60 Hz cycle. Although defined as a linear power supply, there are a lot of current transients flowing in these power supplies.
The Aavik 880 amplifier has four 500W power factor corrected resonant mode power supplies. The 500w power supplies combined with the extremely large power banks mean that the amplifier can deliver peak currents in excess of 80A, so it is not the power supply in the Aavik 880 amplifier that will limit how much you can feed into your speakers in transient and they will never switch.
