I have a Pilot HF42 mono receiver attached to an Electro-Voice Centurion corn horn speaker and I like it very much. It's a vintage mono system using a modern, digital front end. Mono is different and you may not like it. You'll lose nearly all the soundstage/imaging. Mono does have dimensionality, but it's not the 3-D stereo type. What mono does do is give a better focus on tonality and articulation. You should also be better able to position your loudspeaker for best sound in a mono setup. One hidden advantage of mono is that for the same amount of money you will be able to afford significantly better components than stereo.
I would strongly recommend that you keep you existing stereo and if you want to put a foot into the mono world, then do it as a separate system. Try it first before making an all out commitment.
