Look into Meze Audio’s PCUHD upgrade cables made with braided Japanese Furukawa copper. They typically run $270 or so, but they come up on the used market here and there. They will be a nice balance to the Arya Stealth, which can sound tipped up with silver cables. The cable is quite premium and is effortlessly resolving despite it being pure copper.
I am a Meze Audio dealer that has had three pairs of Arya and Arya Stealths in on consignment sales or trade in over the last year, and a year ago I personally owned a pair of Hifiman HE1000SE.
