I’m not sure this will be helpful since my system wasn’t identical to yours.
I owned both the DeVore 8 and Super 8. I drove both with a couple of amps, a Cronus Magnum (not the Magnum II) and a Cary/AES AE-25 and AE3 preamp combination.
I love John DeVore’s speakers. Both speakers, even the Devore 8, were clearly superior with both amps to the Merlin TSMs I had at the same time.
I preferred the AES combo and never learned to love the Cronus Magnum. Eventually replaced both amps with a Cary Sli-80 F1.
As I said, I don’t consider my experience to necessarily be helpful to you but can strongly recommend the DeVore speakers. In addition, John DeVore is very accessible and helpful if you have questions.
