Accousticmass 5 distorted sound
Hi, Im Chris and new to this community. I found my old AM5 system and I was hooking them up with Cambridge A300 amp and the sound from left cube is very fuzzy and distorted at medium volume. Right cube is a little bit fuzzy but much better than the left. I tried to reconnect the cubes, no effect. Tried to swap the cubes, it was always the left one that sounded worse. Tried to connect the cubes directly to receiver (out of curiousity for 5 mins) and they sounded wholesome, no fuzzy, crystal clear.
My suspicion is on the bass module "crossover" since the cubes are all clear when connected directly to receiver.
So I brought them to bose authorize service center and the guy there said there is nothing wrong with my AM5 bass module. They hook my bass module with bose PM amps, another AM5 cube there, and they sounded normal.
Back home, hook them up with the Cambridge receiver and the problem still there. Tried to connect other speaker to the cambridge and all sounded nice. Anyone have idea what is happening with my AM5 system?
Appreciated for any input and sorry for the long post.
