Amp for Acarian Alon IIs

Hello, I'm still trying to find that "perfect" amp for the Alon IIs. The associated equipment is: Analog: Well Tempered Classic+ Grado Platinum or ATOC9 Digital: PS Audio Lambda + Ultralink Preamp: Classe DR6 / Counterpoint SA3000 (for a tube backup) Speakers: Acarian Alon IIs Cables are Nordost Blue Heaven and Black Orpheus. My choices so far are Classe DR15/DR9 or a Chord SPM600. I've also thought about a Levinson 27 but it seems to run pretty hot (my apartment is small). Thanks for the input
