I stream via Cat5 from my router to my Mytek Manhattan II Roon card. This is the only filter that actually helps clean up the signal and improve the musically presentation!! Tried many others they all ruin the sound.
Cleaned up mids, diminished sibilances and crash bells, improved decays and microdynamics. No major shift in tonality. Makes for a calmer playback that makes you wish to turn up the volume.
The Acoustic Revive was used on the input of the ultraRendu + Ghent Gotham DC + LPS-1.2 followed by ISO Regen + Ghent Gotham DC + LPS-1.
It works. I've just added my fifth. I'm a tightwad so I wouldn't invest in these little gizmo's unless my ears tell me that they reduce the noise floor.
