LinQ

NO-COMPROMISE AUDIO ENGINE

HQPlayer Core + NAA (cascade-modules). The breakthrough. LinQ knows no obsolescence.

Our focus was to create an Audio Engine for Roon with zero-setup. The ambitious vision to combine extreme Sound Quality with delight.

The Core exploits the new i.MX8 micro (ARM 64bit), with its incredible performance, low‑latency, and revolutionary power efficiency. And a customized lightweight kernel (UNIX-based).

Roon can be configured to implement of HQPlayer into a Zone. HQPlayer owns the final connection to the Audio Engine, and Roon is just passing along a stream of bits from media files / Streaming services as Qobuz and Tidal. This allows you to enjoy the benefits of HQPlayer SQ and the library management capabilities of Roon at the same time.

The Core is zero-configuration (Plug and Play). The license key of HQPlayer Embedded is pre-installed in our labs and the LinQ is ready to use.

The HQPlayer-based LinQ Core remains true to the philosophy of aqua brand, it is not aimed at digital signal processing.

Formula xHD Rev. 2

The Optologic R2R conversion system

aqua believes that the more musical D/A conversion system is based on the circuit usually identified as "resistor ladder".
This technology has been substituted in the mass-market by the so-called sigma-delta converters.
The sigma-delta converter is a near-completely digital circuit and for this reason it can be can be integrated on silicon and produced at low-cost.
A quality resistor ladder DAC instead uses a circuit based on a set of high precision discrete resistors: at least 2 resistor banks, one for each stereo channel.
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.
In order to separate the digital section from the sensitive analog circuits, 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 clean, noiseless 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.

La Scala MKIII Optologic DAC

The new La Scala MK3 represents much more than a simple upgrade.

Alongside valve/MOSFET hybrid circuitry, we introduce PIBU (Pllot BUffer)-an all-new analogue module developed from scratch in Aqua's own laboratories, which allows for complete elimination ofthe output capacitors. Coupled with the high output current and incredible pre-amp piloting skills of PIBU, this achieves significant improvement, combining state-of-the art electronics and musicality.



Aqua proudly announces the release of the La Scala MkIII, an important evolution of our La Scala DAC. As usual for Aqua, this latest model combines groundbreaking technology, precision craftsmanship, and our unwavering dedication to delivering the truest music reproduction experience.

The La Scala MkIII is not just an upgrade: this version of course includes all the improvements introduced in the recent past, such as C-core transformers, digital AQlink, USB card, etc. but in addition to the VALVE / MOSFET hybrid circuitry, the analog board now features a new analog module – developed from scratch in our laboratories – PIBU (Pilot Buffer).

La Voce S3 Discrete DAC

The new S3 Discrete | La Voce to the next level.

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.

To protect the investment, owners of original La Voce can upgrade to La Voce S3 Discrete DAC. The update for the La Voce units of existing owners consists of the following hardware / firmware modifications:

• FPGA / decoding board cod. P608, high-resolution up to 384kHz PCM and DSD128
• R2R Ladder resistors board cod. P607
• USB board cod. P901 with new firmware
• hardware modification of main board P601
• hardware modification of I2S / USB board P603
