Looking for Speaker Recommendations

Heard of Super Clef or the Clef TL by Speaker Arts by Bob Gross? 

I

I'm with the couple of people that mentioned vandersteen. 10k should get you a pair of treos which are fantastic speakers. I wonder though, if you shouldnt reexamine your Mac amp. Mac's are super mellow and tend to pair well with brighter speakers like B&W and focal which you said you don't like. My feeling was to always start with the speakers a s they Are going to have the single greatest impact on how your hifi sounds. Once you've chosen speakers you can decide which electronics you want to make them sing the best. 

+1 for Salk

For a sound which does not fatigue at all I’d suggest Sonus Faber, particularly the models from a few years ago. The current ones still have a lovely rounded sound though.  

A more esoteric brand found here in Europe is Boenicke - they make speakers with a huge soundstage and an enveloping sound with no fatiguing potential at all.

My next pair will be Salk!
