I have the 52tx and I looked at the 1014tx too. The 1014 is lighter and looks cheaper. The 52tx has copper screws, i dont know if the 1014 does, but 1014 basically looks like a 300 dollar reciever.
I got my 52tx 8 months ago for 500, so it was a good deal. You get the premium look, the better warranty, and a few extras.
The 52tx is good if you want to keep a premium look to your system. In retrospect, i perhaps should have bought a 56tx or something, but at the time I didnt know the difference, and in all honesty, i doubt i'd hear a difference today.
