“Hard to think of immediate competitors.”
To your point, this segment of the audio industry is rapidly evolving. I replaced my digital front end comprising EMM Labs DA2 and Aurender N20 with Merging Technologies +player.
The +player is a impressive piece on its own even before you consider the external power supply and clock options. I really appreciate the fact that +player eliminates the need for external device like Nucleus to run Roon core. The onboard internal CPU runs RoonCore and is controlled by Roon remote app on a tablet or smartphone. All this simplicity, the DAC’s superlative transparency and realism comes at a bargain price of $14K 😊
