IMHO Oyaide is much more better. I recommend the top version mtb case which I use for the last 10+ years. You can put any receptacle you choose inside the mtb case. I recommend SR Tesla (red one), Furutech copper one with no plating or any Oyaide you want. I can describe their sound signature if you want.
It is not sold with cable clamp kit anymore but you can buy the kit separately and connect dedicated line directly to receptacles inside.
