The reason I ask is because I purchased a used table (supposedly between 2-4 months old) and I was picking up distortion in the upper octaves. When I brought it back to the dealer they heard this as well. However, the salesperson told me that it was the cartridge, and that I needed to buy a new one. Once I picked my jaw up off the floor, he began telling me that cartrides have a hae a life span of 2 years or so and that they personally reccomend that their customers replace them every two years. Once I asked them why a (now 6 month old cartridege) would start sounding bad...the dealer began cahnging the age of the table on me yet again, now saying it was over a year-and-a-half old.
So I guess my real question may be, is this bunk or am I just going to be left hanging?
