My personal journey into tubes. Started with all ss, class ab amp. Next tube preamp with class ab ss amp. Next, more efficient speakers, tube preamp, with class A ss amp, Next, tube preamp with variety of push pull tube amps. Next, even more efficient speakers, tube preamp, SET amps.
Having properly efficient speakers is key in tube journey, less efficient speakers will require higher tube power amp which generally will require higher expenditure for amp. Higher efficiency speakers will allow greater choices in more affordable tube amps. I haven't checked efficiency of your Monitor amps, suspect tube preamp may be good starting point for you.
The tube preamp and amp suggestions thus far are good suggestion. Of those suggestions I've owned or own Cary, Joule Electra, Bob Latino DIY kit, Conrad Johnson, Prima Luna, all good choices. I'd suggest EL34 amp, nice flavor in push pull, KT family if you need more power. I also like the suggestion of Decware.
