Most people have not heard A5’s at their best. They have a high ceiling performance wise, and to reach it takes top level electronics and sources.
I was driving mine with an Audio Research Reference 5SE preamp and Pass mono amps, thinking the sound was very good but a little dark and reserved.
Then I bought a preowned Gryphon Antileon EVO amp from a friend and substituted it into the system. WOW is all I can say: the system suddenly came to life and everything was substantially improved. I never would have bought such an expensive amp but used it was barely doable for me and thankfully I pulled the trigger.
Bottom line: A5’s are near top level sound wise, but as stated require top amplification or you’ll never get there.
Good luck!
