The Rotel DX-3 amplifier can also be used with wireless headphones thanks to the presence of a Bluetooth module with support for the AAC / aptX HD codecs. The digital stream is processed by an eight-channel ESS Sabre ES9028PRO DAC chip from ESS Technology, which allows decoding PCM up to 32 bit / 384 kHz and DSD up to DSD256.
