FWIW, in his review of the Synchrony One, John Atkinson preferred the amp/preamp combination of Parasound JC-1 and Levinson 380S with the speakers. These components can presently be found for sale in the listings for close to your $7K budget.
Doug Schneider liked Sim Audio components in his review of the Synchrony One.
I find reading what owners and reviewers use with speakers to be helpful in narrowing the choices (although their selections are not the only possibilities).
