I'd try to find out if anyone else with beads, the 7u intellijel case and specific psu (I think there were 2 options, but not sure) has the same problems

those intellijel psus are quite decent but are noisier than some especially at very high frequencies - which some modules may pick up - they are not for example suitable for video work

"some of the best base-level info to remember can be found in Jim's sigfile" @Lugia

Utility modules are the dull polish that makes the shiny modules actually shine!!!

sound sources < sound modifiers < modulation sources < utilities
