@jeffutter I can understand what you mean. The problem is that these noise issues depend more on the full setup than on the MOD device itself. Everything may work against it. I had this experience even with other types of devices. In the end, even the power strip that you have connected the Dwarf and your amp can influence the noise.
So in other words, we can control what the MOD Dwarf is, but we can’t control where you connect it.
