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.

"Jitter is no longer an issue with most modern DAC’s or streamers that now has internal clocks to combat jitter."

This is totally incorrect as virtually any DAC will provide better SQ if it is fed a cleaner digital signal.

There are many fine renderers or digital bridges that will aid in providing a better digital stream to the DAC than the one coming out of a PC, for example. Some of them terminate with a s/pdif, some with USB and others with I2S. Users have found quality sound with each of these types. The price ranges for these are quite large. Some of the highest value devices use s/pdif as output.

My DAC will accept an I2S input and, theoretically, it should be best. But I did some research on the issue to find, to my satisfaction, that any such device at a reasonable price did not perform as well as the unit I finally ended up with that has a USB output.
