PIBU (Pilot Buffer)
The most important advantage provided by the PIBU is the elimination of the output capacitors, no longer present on MkIII. This – coupled with the high output current capability and the exceptional piloting performances of PIBU – achieves important improvements. The listening tests confirm that the new analog board combines state-of-the art electronics and musicality.
Refinements have been made also on the Digital part, where the pure R2R ladder has new driving circuits implemented inside the FPGA, improving the La Scala’s Digital domain: featuring proprietary Optologic DAC technology, pure FPGA-based R2R ladder DAC.
Therefore, the MkIII represents a significant step in refining the already excellent sound rendering of La Scala.
As our customers know, Aqua’s commitment to sustainability is not a momentary trend: the Aqua modular approach philosophy ensures that legacy owners of La Scala DACs can upgrade to MkIII specifications, allowing them to continue enjoying the best Audio technology.
