Final Retirement Amplifier-Class A-Upcoming Gryphon Essence Stereo vs Accuphase A75


Thinking about one last major amplification upgrade. Specifically looking at the upcoming Gryphon Essence vs Accuphase A-75 class A amplifiers. 
I realize that the Gryphon Essence has not been released yet, but it is said to sound similar, albeit less powerful, to other more expensive Gryphon class A models. So, it is more a question of the sonic differences of Accuphase vs Gryphon class A amplifiers.  I’d kindly appreciate all opinions. Thank you!

New Accuphase E-800 (INT) coming out by the end of the year. Just something to consider. 5K-6K more expensive than the E-650 supposedly. 
Just curious, what do you mean by final amp?  Are you talking about for the next 10 to 20 years, or more?
By final amplifier, I do mean one that will deliver excellent sound with my VAC Ren V preamplifier and a KEF Ref 3 loudspeakers for 10 plus years.
i have not been able to audition a Gryphon Essence due to availability and have not made a class A decision. I did pick up a used GamuT D200i which I’m enjoying and am very impressed with its organic presentation and compatibility in my system. 
With this terrible pandemic everything is slowing down. Just curious if anyone has had the opportunity to audition or own the Gryphon Essence. Your opinions are most appreciated.
