Recently I had bought prion 4 cable for my meze empyrean. Based on meze reviews, I had lot of expectations for meze empyrean. Though I like the sound, it sounded like less detailed. Some grain or hardness was always present. With prion 4, I liked meze empyrean a lot. Nothing is a problem anymore. This cable has smooth, liquid, relaxed sound with tons of details. Everything is clear. No grain or hardness. Peter has guided me with the right info. When I planned to buy lot of adapters unnecessarily, he guided me to buy the right ones. Recently I had bought sparkos aries amp. The sound was better than chord hugo tt2 with mscaler. But prion 4 had ensured that I can get 100% of this amp's benefits. Prion 4 is a solid recommended buy.
