Yeah, most if not all of the 99 cables are portable length, if you need to lengthen it, extenders exist, just make sure the extender is balanced if the cable is, unbalanced if not.
In the future, if you get into the cable game and need a lot of interchangable connectors Hart Audio makes these Multikits which are a ton of fun:

The thing is, the Radiance (seemingly even more than the Elegia) sounds radically different depending on your source, balanced or unbalanced ect, doesn't benefit from a warm/bassy dac, actually benefits from silver cables (a lit of bassy/warm sets do (like I found the Meze 99 unlistenable until I used the silver cable, cleaned everything right up).
While I think cables à la Nordost/Audioquest or other overpriced headphone cables are snakeoil (though arguably could be useful for hi-fi speaker set ups, I don't know as I don't have experience in that forum) - I've also come to appreciate that custom cables, hybrid or silver cables make a difference, but they don't need to be expensive. You can even find gems on AliExpress (hey, don't knock it until you try it) or even better, you can get into making yourself.
So like I said, for me running the Radiance balanced made a huge difference in clarity and impact, even when run from a warmer or occlusive source or chain. And the cable won't be all stiff and gnarly but malleable and relaxed.
