I have not been following mobile audio for a number of years, but I remember that the ESX Quantum amps from years back were one of the best amplifiers a person could buy, especially for the money. I have been reminded of them recently and have some questions.

Is it correct that they were designed by Stephen Mantz of Zed Audio?

Is this the same guy that builds the Kronos and Leviathan amps at Zed Audio Corporation today?

Do these new amps have the same quality and power that the ESX Quantum amps had back in their day? Or when it's time for me to buy amplifiers again, do I need to hunt down some old ESX-Q's in order to find some amazing amplifiers?

Have there been any new players in the field since then that will rival the ESX Quantum amps?
