Well, I have my current cartridge for a little over 3 years. It didn't get mounted until 6 months after I bought it. I was too busy with work and other priorities, and my backup cart was mounted already. So I let it sit on the sideline. After it was finally mounted, I was traveling every week Monday through Friday for over a year, so the system basically sat and collected dust.
The traveling was killing me, so I switched job about 18 months ago. Although I work from home just about every day and have cut back my traveling down to 25%. My system still does not get as much use as I would like. Most of the time, I pop in a CD so I can listen while doing other stuff.
Yeah, it's laughable when you think about it. But I think there are many people out there with decent systems but not enough time to enjoy them.
It has become a "luxury" for me to be able to actually sit down and put on an LP to listen. If I get to do that once a week, I would be happy.
So yeah, I would be surprised that my cartridge has more than 100 hours on it. And, I've been thinking about a new cartridge already. Why? Since I can't enjoy my system while traveling, I guess buying new stuff and browsing various boards has become my temporary fixes while traveling. ;-) Can't wait to get home tonight from my trip!
