New Magnaplanar 1.7 delaminating and buzzing.

You said 1.7 in your OP and I referred to them as 1.7s (ie. plural), just to eliminate any confusion.

I had original 1.7s (plural of 1.7) and about 1 month before the warranty expired, I noticed something not right. I only noticed it with one song in my whole collection but once I noticed it, I looked a bit closer and one speaker either had delamination or shipping damage (barely visible) that I didn’t notice until the warranty was almost over. I bought them from Audio Excellence, an authorized dealer, and was able to have them replaced with a brand new pair but I had to pay one-way shipping costs to have Audio Excellence send them down to the USA for assessment. So I was only out a couple hundred dollars for the privilege of using them for almost a year. I never did hear back about what the problem was.

I bought mine from Stereo Passion in Ottawa Ontario  Canada.  They arrived with brand new bagging, Styrofoam  boarding, inner cardboard  box, and an outer cardboard  box - brand new from the factory in Minnesota. There is no way after so many years of expertise  that an inferior glue should of been  used  and now I have to wait months . I'm  naturally an optimist  but I'm dealing with the trades and everywhere  I turn  people are dropping the ball and could care less. Just saying.

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.

    Sorry for being off topic, but I had a planer driver failure in my Audeeze headphones. I purchased them as a demo from Parts Express in Canada. So even as a demo they carried the full warranty as I had purchased them from an authorized dealer. I contacted Audeeze which happens to be in California where I live. They replaced BOTH drivers with updated new drivers and replaced my leather free earmuffs. All I needed was 1 new driver. They went above and beyond and now have a customer for life.  I’m sorry for your headache and I hope you get a satisfactory resolution. We’re all on this journey together and we can support each other and strive for a good outcome. I hope this public outcry comes to their attention and they do what’s right. Regards , Mike B.  

Audeze. Pronounced like "odyssey", hence the name. How can you own them and not know how to spell the brand name?
