I use the Don Sachs PH16 Phono Stage with the SE84UFO, no line stage.
I know it's not what you asked, it's not the line stage. But I like this combo very much. My original amp was the VTA Dynaco ST-70, and, like the SE84UFO, it did not need a line stage. The Don Sachs PH16 Phono Stage has been great with both amps. You can read about it on his website, under the Custom Tube Gear tab:
