LinQ Interface

About the LinQ Interface

The Aqua LinQ is a network interface developed with a philosophy of using proprietary, in-house technology focused on audio playback quality rather than fast, standard solutions. It features a highly modular design with independent units, each optimized for a specific function and powered by its own dedicated power supply. The device includes a custom-built fully-floating hybrid 2-stage LAN switch module for network communication, providing galvanic isolation to reduce noise and improve sound quality. The LinQ avoids USB interfaces entirely, instead using Aqua's proprietary AQlink I2S connection to connect to compatible DACs, thereby bypassing USB-related sound quality losses. It also offers outputs for S/PDIF, AES/EBU, and dual AES, implemented via a custom FPGA for enhanced performance. The LinQ supports high-resolution audio up to PCM 32 bit 384kHz and DSD128. Its modular architecture allows for future upgrades with plug-in cards supporting protocols like Roon Ready (RAAT) and UPnP DLNA. The device runs on a streamlined Linux-based OS on an ARM processor, emphasizing minimalism and sound purity. The LinQ is praised for its exceptional timing, clarity, and reduction of digital noise, making it a top-tier streamer for audiophiles.
