Well maybe not so much a problem but how am I supposed to upgrade from this?

These monoblocks are such a solid product that I have no idea what could even replace them. They're small, quiet, cool, and sound great. If I want to upgrade to anything else, I'm looking at bigger, hotter, and quiet easily 2-4x more expensive.
Would love to get some help here. I'm completely lost where to go from here. Maybe I should hope for a M225 mk2?
