Which do you prefer for your connections?

Because of the Nyquist Theory and Lightpipe's restriction to 48khz (which really is not a restriction at all), I would think Lightpipe would be the best connection.

Does anyone have definitive information on this?

are there differences in quality?
i wanna buy an apogge Mini ME. is there a difference (or any other pro and cons) if i choose the SPDIF or the AES/EBU to connect it to my DAW?

I have heard rumors lately that ADAT lightpipe is on the lower end of the quality spectrum when it comes to patching digital audio signals.

Anyone heard the same?

Are any of you using ADAT transfer during your projects with satisfying results?
