Okay guys, OP here with an update.
I ended up sending the 6.2s back, which AntiCables honored quickly and without fuss. I had an 845 SET amp coming in from China as I suspected my Emotiva was really letting me down (which, as it turned out, was the case) but my 30 days was up so I had to send them back. Also, these Chane A1.4s are really, really unresolving and seriously lack force/drive. I guess what that boils down to was that my system isn't, and still isn't, really capable of showing the difference between interconnects.
My headphone setup is much more resolving, but the trouble there was that I was feeding a balanced amp (Mjolnir 2) from a balanced DAC (Gustard X20) using single-ended cables, which may have muddled the signal too much to tell a difference between interconnects. Certainly, using my Audio Sensibility XLRs there was a noticable improvement -- which, as I just suggested, might be more due to the balanced topology of my DAC and headphone amp.
BTW, this is the Chinese amp I just bought:
