Koetsus Onyx/Jade Platinum vs Soundsmith Hyperion?

Title says it all. has anyone compared these two cartridges and what were your findings? I heard the Onyx Platinum many years ago at the Munich High End Show with a full MBL setup, and Clearaudio Master Reference turntable with the Koestu mounted. At the time, I had the Benz LPS on my Transrotor Apollon TMD turntable and when I went home after the show, I felt the LPS had the characteristics of the Onyx Platinum...but perhaps not quite the vocal depth. Currently, I own the Soundsmith Sussaro MKII, and Benz Ruby Z, Benz LP and LPS, and Goldring Elite MC's. The Sussaro MKII remains mounted in the main SME V arm, while the Ruby Z is mounted in the other SME V arm. Hoenstyl, since I have had the Sussaro MKII, I feel it gives the LPS a run for the money and perhaps better the LPS in ways that are just amazing. The voices or instruments popping from a floating soundstage are certainly enough for me to be satisfied; yeah, its a sickening hobby. The Onyx Platinum remained my reference for years until I started reading reports about the Hyperion in Germany and in the US. I listened to the Hyperion at the recent Capital Audio Fest and despite the small room, and small monitors, the sound was quite good. I did not have a long listening session as there was only one sweet spot, and Peter was engaged in conversation with another on-looker. So, my interest is kind of high due to the price cuts of the Soundsmith, and this is happening at the same time I was given an offer to trade in my Benz LP and Benz LPS for a Koetsu Onyx Platinum. What say you fellow Audiogoners? Thanks in advance.
