I am currently using the DAC1 with the 525. I am using the toslink connection to the DAC1 and some XLO Reference Type 1 to my amp. I am very much enjoying the combination. I have not heard the Link III in comparison, so forgive me for chiming in, I just had to relate how much pleasure the DAC1 has given me. It is much better, in my system, to my ears, than the Micromega Stage 4 player it replaced. Good luck and enjoy the thrill of the chase!
