The Velocitor Mk5 passive conditioner has had the benefit of continuous development over time, like the different versions of Walker’s Proscenium tt. It looks like a nicely put together product. Another similiarly priced passive conditioner which is also worth of consideration is the Acoustic Revive RTP-6 Absolute which uses the Furutech GTX-D NCF connectors and their flagship Triple C insulated internal connecting wire. And similar to the Velocitor, the IEC has a deep cryo’d silver & rhodium plated pure-copper electrode, and Nano Crystal Formula (NCF) body. These are two passives as the top of their game.
