OP,
Congratulations! Great choice, even if you will be paying them off forever you will likely be enjoying them for many times longer. They are great speakers. Once I found Sonus Faber I realized it was impossible to think I would ever change brands. I have upgraded twice and now have Amati Traditional.
A reminder, they will take a hundred hours or more to break in. It will take time to get placement right. I typically use some process to get them placed. Then wait a few months until I really understand the sound and start slowly experimenting with the details of placement again.
Enjoy... I am sure you will. Not only the sound quality... but it is great having really beautiful speakers.
