Yes, you should definitely explore a better cable. You don’t have to rush and do it. It might be worthwhile just to listen with the stock cable and get familiar with the sound, etc. At some point, I recommend moving on.
I have the XA60.5 mono blocks. I did an extensive audition working with the Cable Co. It was worth the effort. I landed on the RSX Beyond PC. (In the mix were similarly priced cables from Synergistic, Audioquest and Shunyata.)
PS: No offense but, of course, Nelson Pass is going to be diplomatic on the subject.
