After reviewing your system and your well thought out setup, my reaction is "if it ain't broke, don't fix it." Or, at least, don't fix it by going to the opposite extreme.
In my limited experience with them, well designed mini-speakers are certainly capable of producing gorgeous sound on suitable material. But ultimately I think you would feel constrained as to what kinds of music you can listen to with good results.
How much does your system weigh? Does this enhance or detract from enjoyment of high end audio. What might inspire you to be the Biggest Loser on Audiogon?
1)About 425 pounds.
2)The 425 pounds of components fit into my modestly sized living room unobtrusively and without aesthetic or practical compromise. That did, obviously, require that appearance and physical configuration be carefully considered as part of the component selection process.
3)Nothing.
