What are the items/models that you have owned more than once? And loaning "software".

Perhaps it is an early sign of insanity, but I have owned a few products more than once....and some of these do go back in time some. 

Large Advents, 
Dahlquist DQ-10
Magnepan 1.6
CJ-12
CJ-ART
Wireworld Gold Eclipse 3
Classe Tuner-1

There are likely others I am not remembering. 

And yes, after "loaning" some people classic, special pressing albums...they required a re-purchase.  Did you ever have a CD returned with what you thought was peanut butter fingerprints on the surface?   Yes, the audiophile world is an extremely small percentage of the population.  With that said, my best friend I trusted with everything I had audio wise and never regretted it, and I do miss him and his intelligence.
