RCA used market: xlo signature 3 or audience au24e

Hi guys, I would like your thoughts and advise to get unbalanced cables, I will use it between the preamp and the amp. I know the xlo as I have many of them but none of them are in the signature line, and by the other hand I have audience au24e as speaker cables, so I like both brands but haven’t heard neither as interconnects so your comments are very welcome. Thank you!
