Best Cable Option: Streamer to DAC

I was recently told that the inherent limitation of SPDIF connection is PCM 192Hz. I didn't know that. Many new streamers spec 384KHz and I am also told that to achieve higher sample rates (and presumably the full capabilities of the new units) I should use USB rather than SPDIF.  So it made me wonder what actually is the best connection between streamer and DAC:  USB, COAX BNC-SPDIF, AES/EBU or something else?   From a practical standpoint, is there any audible difference from the higher sample rates?  If so, my system should be able to reproduce it.  I'm just looking for help, not trying to start any arguments on here.

You won’t get any definite consensus here....choose a streamer / DAC that does not limits your connectivity. This way you can try and use the protocol that sounds best to your ears.

“I was recently told that the inherent limitation of SPDIF connection is PCM 192Hz.” - True, but I wouldn’t look at this as a limitation since current streaming services tops at 24bit/192kHz resolution. Jitter is no longer an issue with most modern DAC’s or streamers that now has internal clocks to combat jitter.

“is there any audible difference from the higher sample rates?” - Yes, as long as you have a system that allows you to appreciate the difference. You do need DSD files to appreciate the uptick in SQ. In this case USB is the obvious choice.
