If you read up on the Muff Wiggker forum, you'll are lots of complaints about unwanted him and noise with the MN busboards. I'm kind of stuck with them for know since my cases came with them, but the minute I can, I'm swapping.

The best supplies are linear, like Doepfer uses. Super quiet and no issues as long as you stay below the power limit. The problem is, no one else wants to make a linear supply because off the licensing costs. They are also bulkier, and won't fit in today's more shallow case designs.

I'm either going to swap my MN for the Intellijel power, or design an external enclosure that will house 3-4 linear power supplies to feed into my Goike cases. (2x6u aluminum boards configured as a folding design and a 3u boat in front)
