Is your budget for the preamp (only) still around $3K?
I looked up the input impedance of what I believe to be your SS power amps and they were in the 20K-27K range.
Both should mate fine with contemporary tube preamps, but it wouldn't hurt to throw out the model number of the preamp(s) you are seriously considering.
Never heard Meitner and the only YBA was an integrated amp a long time ago.
I did have a CD player and an integrated from YBA's super budget line (forget the name), but they were just OK and nothing like the YBA branded amp.
