I can't live with a set of speakers for more than a year, it seems. I don't hate any of them - at the time of purchase / listening / tweaking, they are always the best thing going. But once I get past that point, my mind wanders. My mouse goes clicky-clicky, and suddenly I'm rushing across town, dropping coin on the next big old thing, and hastily selling what I can to make up for it, sometimes at a "profit", since most things I buy, I buy used. I feel it's endless and will wind up with me in divorce court, or in a theater decked out with really good gear that is always about 5 years behind the SOTA. That's OK with me.
