Why Isnt Techincs 1200 Considered Audiophile?

I've had the  SL-1600MK2 since the early 80's.  I bought it while stationed in Germany and paid $249. This thing is built like a tank; it is not a "DJ" turntable and cost more than the SL-1200 even thought they look and function about the same.  It's still going strong and sounds "audiophile" enough for my ears - and budget.  

Based on my research and comments on this site, I do plan to buy an Ortofon 2M Black cart to replace my Pickering XV-15 cart.  Not sure what to expect in sound improvement, but for the price difference alone I'm sure it will be better.
