I have a JBL Metregon, your Paragon's little brother. We are both very lucky people!Both the Metregon and Paragon are pretty efficient and I have run mine with both tubes and ss. With the Prima Luna Prologue 6 monos (with either Psvanes KT 88 Mk II IIseries or JJ E34L Blues the sound is as you would expect very tube like. Warm and rich with the E34Ls I think surpassing the KT88s in a very sweet and detailed midrange. The power difference isn't that great between the 2 sets and the Paragon doesn't need it anyways. The KT88s have a slightly deeper defined bottom end. I ran a friends' 12 w tube amp to demonstrate it for him and the Metregon could still blow out the room.
I have many hours running the Metregon with a Pioneer SX1050 (fully refurbished) and because the 1050 was designed to be tube like there is very little difference except because of the 1050s power the bass is stronger and I think more detailed. The mids and highs are very nice and certainly very acceptable but not in the cat of either tube set. I think the horns like the tubes better.So take this for what it is worth, I really don't think you can wrong either way
Best
