Your Thoughts On My Sonic Lab Cartridges

With the baseball season arriving,like a child I'm getting Spring Fever and thinking of purchasing a new cartridge.
If you heard this cartridge,I ask your impression please.
Also I understand they make The Eminent Cartridge under one or more different names.Anyone know which cartridges are actually Eminents?
You can ask Mr.Matsudaira himself? Send him your question.
Syntex,I perused the analog gear in your system and greatly respect your opinion.I am analog only and currently use a Temper V and have had the 90X.If My Sonic Lab forced you to digital I guess its not for me.
Also my thanks to Prcinka for the link
