I do appreciate all the feedback. I have learned a lot here at this forum regarding all aspects of audio.
Especially useful are the responses from people who have done it.
I have left the speakers there for 3 years no problem.
Funny, but it just occurred to me just before reading the post, lots of gear shipped in container ships.
As my gear has moved up to higher end, it is a significant investment so may start with some of the less expensive stuff. Problem is you get spoiled. After hearing N10 through a Yggy it is hard to go back! But I recently went back to my N100/Gungnir/Senn HD800S setup. Sounded great! But when i went back to the N10/Yggy/Focals sounded much better, if I didn't now know about how upgrades sound I think I might be happy with it.. The N100/ Gungnir can't handle the Utopias, they are too revealing.
I think I will go with shrink wrap and dessicant. Maybe take my tube amp home one more year.
My cottage is in a little fishing village, so I do have alll year resident neighbors and I hear of little theft in the village, more common in isolated beach houses I think.
Thanks to all and Happy Holidays.
