Eitan,
I have bunch of old Canare cables. They are over 20 years old now. I bought them when I was living in Japan and they are still as good as new. Very high quality product. Unfortunately at the time I didn’t realize that they were unbalanced! So I have a huge box of great guitar cables:-)
Out of curiosity, I did an experiment and plugged in a balanced cable in one of the stereo outputs of the AK and one of the unbalanced Canare cables into the other and there was absolutely no difference in either volume level or audio quality so my interface (UA Apollo) must be compensating for the unbalanced signal or something.
In any case, I still need a bunch of cables to wire up a patch bay and to make some additional connections. Definitely makes financial sense to solder up my own and I have had very good experience with the brand. Thanks for the recommendations.
