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!
