PS Audio has delivered an INCREDIBLE solution to resolve this issue. The company uses a proprietary protocol with their new DMP Player and the amazing DS DAC. Use of an HDMI cable delivers a digital handshake using a high speed data transfer between transport and the DAC. Based on what I understand the manufacturer of the DAC must pay licensing fees to Sony in order to be granted permission to decode and play music. Some chose to pay others did not. I2S is the technology innovated by PS Audio but any maker can use it, from what I understand. I’m pasting some information I copied directly from the website below, and let me tell you, the overall experience of this player is simply unbelievable for both CD and SACD. See below:
“Now, with the introduction of PS Audio’s revolutionary new memory player, DMP, owners of our DirectStream series of DACs can uncover all that they have been missing. Based on a proprietary handshake protocol between DMP and PS Audio DACs, through our advanced I²S interface, pure DSD is streamed to, and processed in, the same reference quality DAC used by mastering engineers.”
