The biggest bonus with wax is the cleanliness when changing gears. I don't think it's the chain or lube specifically that is the noise generator but perhaps the chainrings/cogs. I run DA for both and it has often been commented how quiet my bike is. You don't hear me coming like with other bikes. I've run a few different chains and lubes since on my way to my current sram chain and wax setup and all have been very quiet
