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.
