Headphoneus Supremus
I have used PW Audio August Fun with U18t with great results. It's the younger brother of 1950s and a tad warmer and fuller sounding than 1960s 2-wire.I think it depends on your budget, but generally I prefer pairing up U18t with a neutral warmish cable. I have to confess I never heard PWA No.10, but PWA Moloch offers great value for its price imo. It widens the stage while smoothening high frequencies.
But of course if you want to unleash 18t's potential the flagship cables are waving at you 1950s Shielding provides an overall upgrade, First Times Shielding maxes out technicalities while Orpheus recreates lifelike vocals.
