The Rotel A14MKII AB-class integrated amplifier occupies a top position in the company's 14 Series series. Its main difference from the previous flagship A14 is the improved circuitry and the replacement of some components in key nodes of the circuit. The changes also affected the power supply and output stages, and instead of the built-in AKM DAC used in the predecessor, the MKII version uses a TI (Texas Instruments) chip capable of working with PCM (up to 32 bit/384 kHz) and MQA/MQA Studio formats via an asynchronous USB port, which is important, for example, when connected to the TIDAL streaming service, which uses an MQA container to broadcast Hi-Res audio.
