Ok, well you are new indeed. Here is the quick rundown on my answers for you: THD doesn't mean much (I am an electrical engineer). Tubes do indeed produce more distortion than transistors but your ears hear it differently. McIntosh makes some great preamps with their customary 0.005% THD and you won't ever have any tube hassles - but you will have to buy used though as new Mc preamps are way more than $1500. I would suggest the C41 but it doesn't come up for sale often.
Tubes are really cool. I used to only like transistors but now I have warmed up to tubes and have 2/3 of my system using them. If you have the desire to do a little homework on the subject, I would highly recommend a tube preamp in your future. Knowing what speakers you have would make it easier to be more specific as to models. Also, do you know what type of sound you like i.e., warm and involving or cool and analytical? Arthur
