USB cable recommendations

@fire_water funny thing about my experience with Audience…I always liked their digital cables and even power cords which work good on digital DACs, and I really dig their speaker cables - had AU24SX and upgraded to FrontRow that’s been in my system for quiet some time now. But I never had good luck with their interconnects. 
Tried AU24SE, AU24SX and FrontRow XLRs. Always preferred some other brands/models. They are not terrible but they never wowed me. Your experience could be different. Try them but make sure you can return. 
 

Also…when you get DPS-4.1 try it on amplifier as well. 

OP, try as many as you can without driving yourself insane haha.  I would say 3 or 4 max.  If you have a dealer they will often let you borrow them.  And if one is out of your budget but you like it, check the used market.  I got my Alpha retail for $2000 for $600!

@signaforce I was lucky to get the Pink Faun USB second hand for a crazy good price. 

I recommend finding a dealer who will let you borrow some products or else buy and return with minimal/no fee. Or, the smaller internet direct brands like Veritas, Audio Art, Triode Wire Labs all have great demo terms so you can basically try them out for just the cost of shipping. There's nothing better than hearing them in your own system.

There’s absolutely no substitute for auditioning cables in your own setup. I once had a full loom of Audience Au24SX, and while they are reasonably good; as @audphile1 pointed out, I felt something was missing. At their asking price, I couldn’t justify keeping them in my system.

Audience cables do a solid job of transparency, natural coherence, and a fluid musical balance, which works well for many systems. But given how closely your rig parallels mine, I’d highly recommend adding Combak’s 聖 HIJIRI Million “極 KIWAMI” HGP-X XLRs to your audition list. 

IME, HIJIRI cables align beautifully with and handsomely complements Accuphase sound signature: lush tonality, rich midrange presence, and an immersive musical experience that truly draws you into the performance.

I’ve owned a full HIJIRI loom since 2021—speaker, power, and interconnects. They aren’t inexpensive, but they put an end to my pursuit of chasing anything else out there.

@lalitk i should have reached out to you initially. I'll look at your suggestions.  Thanks!
