I guess I praised these speakers a bit too soon. My neighbors recently moved so last night I thought I would go a bit higher with the volume to try and find an upper limit. The pre was in the low 80s for the first time and Foghat's Slow Ride was playing, when the right channel went out. All the electronics seemed fine, as did all connections. Today I attached a spare center channel speaker to the right channel's speaker cable, and it is fine. Hook the S5 back up, and nothing. There is a faint sound from the woofer, but nothing from the mid and tweeter.
Darn. Now to contact Magico on Monday to start the repair process. While I am disappointed here, my biggest regret is the agony of having to box it, ship it, get it back, and reverse the process.
What a bummer. It will be interesting to learn what the problem is. If I recall correctly, Magico doesn't use any sort of resistors (like Wilson does) because they feel it adversely affects the sound. Given that you don't hear sound from any of the drivers, it must be some sort of crossover that failed?
