i trust you have seen this useful review of your speakers, where the (pretty good) reviewer uses three different amps with them, two of which are tubed... the two, a leben, represents a somewhat more classically tubey sound, and the lta amp a more modern tube sound - he is pretty articulate in his writing about how the music is presented with the different amps thru these speakers
maybe this will help further inform you in your consideration
i would say the best way (cost effective, and just plain ol effective) to experience tube sound in your system is to get a decent tube integrated... buy it used, and resell it if it doesn’t float your boat
