Aqua HiFi Formula xHD DAC
The Formula DAC is the first in the aqua’s production to show a proprietary D/A conversion system, that we name Optologic. The signals sent to the resistor ladders are generated by a proprietary digital circuit, implemented inside an FPGA (Field Programmable Gate Array). Formula has a sign-magnitude converter structure, and this requires not two but four 24 bit resistors banks, each one made of very low tolerance discrete resistors.
Aqua La Scala MKII Optologic DAC
Aqua HiFi La Scala MKII Optologic DAC proves that an instant classic does not mean a product whose destiny is to become obsolescent, like most of the products in the high-end world. The already extraordinary sound quality of this icon is now improved in every aspect: time coherence, microdynamics, timbre, and without losing that magic atmosphere for which La Scala is widely renowned. La Scala MkII keeps the VALVE / MOSFET hybrid circuitry, with now a pair of specially selected ECC81 tubes – a High-Frequency triode – for its extremely low noise and superb transparency.
Aqua La Voce S3 Discrete DAC
Designed to provide absolute modularity, the La Voce S3 is a pure R2R ladder – FPGA-based DAC without digital filter. It has a sign-magnitude ladder converter. The absence of digital filtering means no processing of the input signal. The original digital samples are translated to the reproduced sound, preserving the transient shape and avoiding any ringing. In this way we also avoid the “intersample overs” problem that is vital to faithful reproduction, considering current recording studio practices. With our R2R conversion technology the sound is natural, fast, dynamic, and without the sense of compression characterizing others converters.
AudioQuest Beetle DAC
Beetle is a multi-purpose DAC for today’s many different lifestyles. Capable of delivering naturally dynamic, uncompressed music via its high-performance optical or asynchronous USB inputs, Beetle adds exceptional convenience and surprisingly beautiful sound through its asynchronous Bluetooth technology.
AudioQuest DragonFly DAC
DragonFly plugs into a computer’s USB port to bypass the computer’s compromised audio circuitry and deliver cleaner, clearer, more naturally beautiful sound to headphones, powered speakers, and complete audio systems. Convenience and performance are no longer mutually exclusive. With DragonFly Black and Red, any computer, laptop, tablet, or smartphone can be used as a true high-fidelity music player, allowing music lovers to enjoy beautiful sound wherever they go, whenever they please.
Ayre Acoustics QX-8 DAC
The QX-8 Digital Hub provides a total solution for state-of-the-art digital music reproduction.
Berkeley Audio Design Alpha DAC Reference Series 3
The Alpha DAC Reference Series 3 contains breakthrough technology that redefines the potential of digital audio quality.
