La Scala MkIII Optologic

About the La Scala MkIII Optologic

The Aqua Acoustic Quality La Scala MkIII Optologic is a third-generation high-end digital-to-analog converter built around Aqua’s proprietary Optologic platform. It uses a pure R2R ladder architecture with FPGA-based digital decoding, no digital filter, and a hybrid analog output stage that combines **ECC81 tubes** with MOSFET circuitry. The MkIII adds a new PIBU analog module, eliminating output capacitors, and is described as a refined benchmark DAC with modular, future-upgradeable construction. The La Scala MkIII is a factory-fresh 2025 configuration in the MkIII upgrade path; Aqua’s earlier La Scala Optologic models and upgrade options indicate the product line is actively evolving rather than discontinued. The only explicit current price found for the MkIII is about **£7,850**.
