I used the Triton for a few years with Daedalus speakers. If he is happy with the Triton there should be no complaints using Daedalus. The Athena is in the 8k range (figured that would be in budget since you mentioned auditioning a 7k pair of speakers)... Send him to RMAF to hear Daedalus. Looks and sounds beautiful! And worked well in all departments with my past Ayon Triton integrated.
AYON TITAN INTEGRATED AMP
What speakers are people using with this amplifier?? I guess I am looking for the best match possible.
