The Turandot is the new height that Opera audio has achieved in a 24bit over sampling CD-player. Advanced digital and analogue design, construction techniques and components, which have been carefully selected, have been combined to provide the highest performance. The Turandot is built using 2 separate power supplies, the CD-loader support remains the same developed for the Droplet CDP5.0, which is also a sandwich type graphite float for exceptional stability to control drive vibration. Along with a clear super clock technological improvement over the previous design, the Turandot has achieved the ability to reduce the digital distortion close to the theoretical minimum for a 16-bit jitter-test.

Calaf, the biggest output power integrated solid-state amplifier in the Consonance line, there is very little headroom available beyond dynamic conditions under for the Calaf. Massive toroidal transformer with independent secondary windings and a bank of eight 10,000uF electrolytic reservoir capacitors for each channel's main power supply. There are also independent preamplifier sections for each cannel and both of these have their own power supplies. Both left and right channels are built as mono power amplifiers, each with seven pairs of high-current transistors mounted onto a thick copper bus bar. This is bolted onto the extruded heat sink that's visible on either side of the amplifier.

Combined with the advantage of class AB and the class A technology, the Cool Class A technology actually achieved the same linear sound performance but without the normal need of a big electrical current, as Class A does.
