I tend to agree. They chose a great cable, great connector, and good strain reliefs so why make it interchangeable? I like to be able to change cables, but only if the original one is a performance bottleneck (which the T1's isn't ) especially because it's so easy to re-terminate for balanced use.
Here you go, I'd rather get off the shelf plug-and-play XLR cable than reterminating stock one and voiding warranty.
Yes, it's easy to do if you have very basic DIY skills and soldering iron, but not everyone is handy here.
