Ultimate Performance ESS Sabre ES9038PRO DAC
Audio circuit of the M7 is based around ESS Sabre ES9038PRO DAC. The flagship model of the ESS line, power hungry 8-channel beast and DAC that we started to really like last year, when we implemented it into our top-of-the-line CD Player CD3.2 (21). All the experience of adapting it into a classic Hi-Fi machine helped us in optimizing its performance for the M7. The ES9038 PRO is run in its current-mode operation, combined with a matching ESS ES9311 voltage regulator, a power circuit adapted from the M9 and our in-house developed I/V conversion stage. When paired with our OP + BUF amplifier architecture, which was further optimized for the M7, we are actually getting our best measuring portable player so far.
