Product Description:

Award-winning A 52 performance is back- now with 44% more power!

Home Theater Review once described the original A52 as "a truly musically engaging amplifier with an alter ego that likes to blow stuff up should the mood or movie strike it". Building on this legacy, the A 52+ comes equipped with significantly more power output than its predecessor, ensuring it can drive virtually any speaker with even more dynamic and explosive force, while still maintaining its captivating grace and musicality.
