I have heard those speakers a few times with Ayre Reference gear, D'Agastino gear and darTZeel or however their pattern of letters is supposed to be.
For years I was "chasing the dragon" after hearing those with the Ayre gear as it is one of the most memorable listening experiences I have ever had and what drove me to design my own speakers and start Verdant.
The difficulty is that you could easily buy a pair of amps that you like less than the Classe or could find ones that blow them out of the water. It is a matter of taste. I am biased heavily toward musicality and staging rather than accuracy and measurement. It is why I am biased heavily toward tube gear or very musical SS gear like AVM, Riviera and Audia Flight.
What do you want more of? What is missing? Are there moments when you are disappointed and how? Answer these questions. If you can't spot issues then maybe you just have an upgrade bug and this could and should be scratched elsewhere in your system.
