Manley Massive Passive

After years of curiosity I bought a Manley Massive Passive and placed it between my Classe Preamp and Classe monoblock amplifiers. I know there are many audiophiles out there that are dead against any tone control, including myself, until this Manley MP arrived today... amazing! I don’t know why Manley doesn’t market this unit to consumers. Best 5K that I’ve ever spent for my audio system. Even set in bypass mode, it makes everything sound amazing. Has anyone else had the pleasure of buying one of these?
