Your Bpt unit will simply see a regular Ac input from the Equitech. It’s ok to plug it in. The Equitech will reduce the amount of “common”mode noise the Bpt will have to deal with. Theoretically a benefit. The Bpt unit also should address “conducted differential noise” so should give even quieter AC. I believe the best benefit will be obtained using the Bpt to further isolate your digital from your analog. So I’d just plug digital into the Bpt. I’m interested in your finding. My experience with my Ref level Spectal/MIT system is that ‘appropriate’ additional isolation of digital has been audibly beneficial. I’m all ears ;)
