New Magnaplanar 1.7 delaminating and buzzing.

Only six month old and those type of problems?  Magnepan should step up and replace both, no questions asked.   Sounds like a problem with the adhesives used.

Mike, You are not the only one I have heard that from regarding Audeze.   Some companies really do go above and beyond.  Grado, excellent service, Zesto ....unbelievable service.    

I wish the OP luck,  do manufacturers realize the damage control they could avoid by just taking care of customers?   Magnepans aren't my thing, but after reading this story I would tell friends or family to avoid Magnepans .   Honestly they really are a niche speaker,   I get that they have a unique presentation but there are so many great speaker companies out there fighting for your $$$$
