Acoustical Systems Evocator Phono Stage

We herewith introduce the Evocator our full-feature reference tube RIAA phono stage.

With the Evocator we complete our product portfolio as it was the last major component "missing" in the all analog front end chain.

The Evocator all-triode-tube reference RIAA phono stage featuring:

Full feature 4 phono inputs – RCA and balanced - w/3 selectable gain stages for MC

2 outputs – RCA and balanced – 600 Ohms studio pro standard

Front panel selectable load for capacitance and impedance for MI and MM

Front panel selectable load impedance for MC inputs

Front panel selectable phono phase 0° and 180° inverted

Front panel selectable Mono / Stereo

Separate power supply with tube rectification and

DC tube regulated plate supply

Selectable grounding route for zero hum

Operates 100 to 250 V ac line – 50Hz and 60 Hz

Highest quality connections: WBT (RCAs), Eichmann (RCAs choice) Furutech (IEC socket and XLR (choice)), Lemo (power supply to phono stage)

Made with PTFE-circuit boards gel-cushioned for vibration isolation, pure silver foil in oil capacitors, premium grade triodes, top-class RCA and XLR connectors and entirely non-magnetic high dampened alloy cabinets

Entirely designed and made in Germany

Aqua Acoustics Formula Optologic DAC


The Formula Dac is the first in the aqua - acoustic quality’s production to show a proprietary D/A conversion system, that we name Optologic Dac. This conversion system follows the same multibit technology (already used in the previous world acclaimed dacs such as La Voce and La Scala) but with a discrete R2R resistors ladder instead of Burr Brown PCM1704 dacs.

Galvanic and magnetic isolations are implemented between the FPGA and the four branches of the R2R ladder converter. This creates complete isolation of all digital circuitry - including the clock - from the analogue section for a pure clean ground plane. It also plays the main role in the differential management of the R2R ladders, achieving perfect symmetry between the counter-phase halves. The result is the highest tonal contrast and naturalness never heard before from digital sources.

The Formula Dac uses no digital filter or any other compensation, relying instead on maniacal attention to each sub circuit. The analog and digital power supplies are executed purely discrete by extensive use of BJT, Mosfet, Jfet and ultra-fast diodes. Passive parts were selected not just for the best sonic result but also for their top quality, longevity and reliability.

With the exception of six superior quality electrolytics, all other caps are Tantalum, solid-polymer OS-CON and double-metalized MJP. The signal path itself is direct-coupled and free of all capacitors. The two output stages (one single-ended, one transformer-coupled balanced) use discrete BJT and JFet with metal-film resistors. All the electronics parts show an ultra low RF noise.
