Wojciech Pacula has posted a review of the Verictum X fuse (~€90) at High Fidelity. His conclusions:
“X Fuse changes sound clearly – it is ca. 5% of the sound of even very expensive products, which is a lot, indeed. It makes sound denser, more substantial and makes less mess in the treble. It makes listening to music more comfortable, as if a small thorn – invisible, but still irritating – was removed from our finger.”
