• DAR’s favourite bits by John H. Darko

"No DAC impressed me more in 2014 - or any other year for that matter - than the Aqua La Scala MKII."
"the best-sounding D/A converter we’ve heard to date. The La Scala’s almost sentient way with drama and textural reveal puts it at the very top of the Darko DAC Index"

• La Scala MKII - The publisher's year's favourites by Srajan Ebaen

"La Scala gives the feisty one-finger salute to DSD might tell you how I feel about that fashion madness. That it manages an ideal balance between speed and substance tells you why it had my vote. A most analogue digital deck, albeit sans volume control!"

• La Scala MK II Blue Moon Award

"With the La Scala II, I got both plus. In that sense it was an audio equivalent of the Buddhist Middle Path high up the mythical mountain."
"Put my name down too on this growing list of outspoken admirers for the Aqua Hifi La Scala II."

• La Voce S2 dac AWARDED again - Stereo Times Most Wanted Component 2015

“La Voce's big brother, Aqua HIfi's La Scala, is justifiably well regarded as a master of musicality at a non uber-DAC price point.
Little brother La Voce… R2R NOS DAC is the genuine article; incredibly natural sounding with all genres, easily winning a place in my system up against various and sundry more 'modern' Sabre and delta/sigma based brethren.
Some things were done a certain way for a long time for good reason”

The Optologic DAC
Our new flagship FORMULA 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.

Technology

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.
