Last year I replaced my 850 w/ an 860x and I agree w/ Jfrench. I found the 860x to be more resolving and more refined than the 850(both were directly conected to my Audio Research VT-50) Also, the 860 has a much better transport. Although the 850 is an excelent player (probably one of the best in its class) I would recommend the 860x or even 861 if your budget permits. Hopefully you will be able to listen to both the 850 and 860 and come to your own decision...either way you will be getting a very high quality product. Good luck...
