Toslink, HDMI or USB or better dac?

currently i stream music from my PC to a headphone amp and a stereo receiver. I use a Toslink cable from the PC to a pass-through 192KHz 24 bit Mutifunctional DAC the analog output connects to a little dot MK3 for headphones. A second Toslink continues on from the Converter to the stereo receiver with it’s own built in DAC. Is their a better Option?

Paul Posted a couple videos about toslink vs aes vs coax. Ive looked for the link but i cant find them at the moment.

thank you I will look
