Lyngdorf and Phono Stages

I am considering bringing in a Lyngdorf TDAI 2170 or 3400 for an audition and would like to get some feedback with owners or former owners who play a lot of vinyl. It appears that acclaim for the Lyngdorf with digital is universal, but I have read some mixed reports on how it sounds with vinyl.

I guess my questions are these:

1) What phono stages have people used and loved with the Lyngdorf? What phono stages have not been a good match, due to impedance mismatch or some other reason?

2) Are the sonic characteristics of the phono stage still apparent, or does the Lyndorf put its own stamp on the music? In other words, is there a house sound with the Lyngdorf? I experienced this with a Devialet that I had a few years ago and felt my analog playback lost a good bit of its magic in the conversion process.

3) Is there a difference between the 2170 and 3400 with regard to vinyl playback?

Since I have a square room with a cathedral ceiling and little wiggle room for room treatments beyond a thick rug and audio-friendly furniture, I am intrigued what the room correction feature of the Lyngdorf might do for my system. On the other hand, I need to be sure that I will be good to go with vinyl, which I play about 50 percent of the time.

Any feedback would be appreciated.
