Check out the Canor AI1.10. Andrew Robinson (Recovering Audiopile) just did a review over at the recovering audiophile and simply raved about it. It is a push pull KT88 that delivers 20w in triode, 40w in Ultralinear. If you aren't familiar, he has a YouTube video channel and 200K followers. If you are, my apologies. No intent to be condescending. Just trying to be informative.
I am the importer so I am clearly biased, but I have been listening to one for a couple months driving Vivid's in a small space. I think it will do the job well on your Devores.
Otherwise, Sugden is my favorite amp of the ones you have listed.
Line Magnetic is easy to get tubes for but good ones are pretty expensive. Upgrading tubes in that whole amp to the best options will add quite a bit to the cost.
