@bikeboy52 I'm both a DH Labs and Aurender dealer. I like the Mirage USB cable a lot for the money. I even purchased a Synergistic Research Galileo SX USB cable, as I do utilize the Galileo SX line for most of my loom. I could not tell the difference between the two, so I sold the Galileo SX USB cable off. That said, since the Pontus reclocks signal anyway, you may want to consider using a coax cable instead of USB. The origin clock inside the N200 is quite good, and reclocking it with the Pontus is likely even better. In my experience, Coax and AES have been my continued source interface, producing a thicker, more effortless sound, as I find USB to be more fragile and brittle with Aurender.
That said, for interconnects, the DH Labs Air Matrix Cryo interconnects are really quite good for the money. I prefer it over their more expensive pure silver Revelation and equate its performance to be close or equivalent to the $2K+ Synergistic Research Atmophere Level III cables. Cerious Technologies Graphene Matrix interconnects are also quite good and can be had for $700 or less on the used market. They retail for $1400, though. Any other cables I'd recommend go even higher than that. Both suggestions will be much more open and revealing than your Absolute Copper. I used a few of them early on in my journey and found them to be too rounded on the top and closed in / stuffy.
Another thought for cabling on digital - power might be even more important than the interconnect. The digital signal is incredibly delicate, and proper delivery of current without any peaks will result in a more revealing and more fatigue-free experience.
Last, the N200 is quite a good unit, and one of my favorites in the Aurender line, but it may not deliver the body of a $50K vinyl rig. I've compared the N200 to the N20 to the N30SA (all of which I've had on my floor at one time) and will say that the N200 gets you really far compared to most other streamers, the N20 gets you awfully close to reference level, and the N30SA at reference level is typically not worth it for 90+% of audiophiles. If I had never heard the N30SA, I would be quite happy with the N20. It takes some pretty serious critical listening to discern between the two. The difference is much more obvious when comparing the N200 to the N20.
Hope all of this is helpful.
