I’m not familiar with the Magnus, but both the Lavri and Supra seem to get really good reviews. I’ve got the Lavri, and although I haven’t been able to compare to the Supra I can just say my streaming with the Lavri sounds notably better than spinning CDs (granted, lotsa variables in there). That was a huge surprise to me. I’ve no idea how it compares to the Supra or others, but I can say without a doubt the Lavri elevated my digital streaming game at a very reasonable price, at least by audiophile standards. I can tell you this — I’ve got balanced interconnects, a balanced headphone cable, and the USB cable from LavriCable and they’re all great. Lots of detail, air, tone, 3D imaging/soundstage with absolutely no harshness or brightness that’s often associated with silver cables. I don’t know how they do it, but they’ve managed to combine both the strengths of silver and copper in one cable. If you want added warmth these certainly won’t do that, but if you’re just looking for the truth the rest of your electronics then I can highly recommend the Lavri. Hope this helps, and best of luck.
