This is something that drives me nuts! I like to try different gear. I have purchased numerous pieces of equipment to try them out simply because I have heard excellent things about them and I may keep them 6 months or so. A Coda CSIB Integrated is just one example. I only buy gear that is in excellent shape (I don't care how many owners it has had) and I sell it in the same condition if not better. So somehow my ownership of the item has tainted it in some manner? I don't give a hoot if ten people have owned it. What matters to me is the condition. How is a piece any better if only one person has owned it or worse if three people have if it's in excellent condition? It's used gear and you are saving a ton of money (usually) over new.
I have a Plinius integrated for sale right now that is a current model that is less than half the original price and people act like since someone owned it prior to me It is somehow tainted and to be avoided. It's an excellent amp! It's in like new condition......it's less than half price! I don't get this obsession with "Are you the original owner?" or "how old is it?" Who cares! If I had held equipment I have tried to the same standard, I wouldn't have tried so many different pieces of gear. Geez, get over it folks. You're buying something used in "X" condition at a price much lower than new. What more do you want? As you can tell this obsession with ownership drives me crazy!
