The tubes are EML 45 solid plate, which are my favorites, but I do roll in Vintage globes and ST's.
The speakers are Tekton Design Perfect Set 15. Very good match for the AE 45.
Would love to hear the mono-blocks with those 105dB efficient speakers, not surprised that you are loving your sound!
I got my AE 45se stereo from Alan about 5 years ago and like you feel in love with what the 45 tube is capable of.
I run mine with Tekton Perfect Set 15, 98 dB and get deep bass...
