Most tube preamps that are not single stage will drive the Parasound and even a 10k amp with no problems.
If you want to go single stage you will need to have a preamp with an output transformer - like the Coincident Signature. Which is the best line preamp I ever heard and by some margin. Their phono based pre is also at that top notch level.

Thanks, I admit I am going by my own research, and what I read, not real world experience. I am thinking of changing over to a tube pre for my Acoustat Model 3 based system at some point. I believe the input impedance of my Acoustat TNT-120 is 47 kOhms so I have had some concern about what will match.
Most tube preamps will find the 47k easy to drive. Those with feedback SRPP, cathode follower or Cascode to lower output impedance should not have a problem onlly single stage preamps (really few of those around) would have a slight problem.
