Cheers. Honestly, I always aimed for the right choice regarding cables, prioritizing durability above all; I took my time with it, and whenever a family member or friend traveled to the US, I’d have them pick some up for me—in the end, they cost the same as generic ones back in Argentina. Just to share: I moved on from a NAD 325BEE (which I loved) because I could get a good price for it, and I spent some time using an Aiyima A20—guided by Amir’s review—to run the D50 III via balanced connections. Then the problems started... first, the issue with the subwoofer output's HPF, and then the huge difficulty I had EQing the sub, even with REW. When the Buckeye amp arrived, I first listened to songs I know by heart, and—wow—what a difference those 150 watts made. The bass when "So What?" kicks in... it was the first time I’d heard it sound so full and punchy; I’m thrilled. I mean, even though the Aiyima measured better on paper and according to Cloud (I later realized the NAD has a circuit that acts as a sort of reserve for peaks), I didn't feel like it was an upgrade. Cheers, everyone.
