Speakers to hang on to for LIFE

After 9 years with my Proac Response 3s, I recently decided to change speakers. As you can tell, I'm not an upgrade fever patient. I want something I can live with for years & I think the best advice I'm gonna get will be from those who have & are still living with their speakers for an extended period of time. Please tell me why too. Thanks.Bob.
I think I am "done for now", and maybe forever, with the new Intuitive Design Summit loudspeakers which are about 3 weeks old. About 3500 for the speakers and ~1500 for the stands, these are utterly phenomenal. I can't even imagine what the Intuitive Design Denali loudspeakers must sound like (priced at 40K per pair). I am sooo happy with these--I HAD been seaching for this level of sonic performance all of my adolescent and adult life--now I am THERE.
These little speakers could produce music like you could never dream of. Small book shelf. Big soundstage. Huge dynamics. wow.
The Summits sounded good at RMAF. I heard the Denalis in Denver Sunday night after RMAF was over. Impressive dynamics. They're $65k, not $40k.
All Rogers speakers:

I have Studio 1a, Studio 1, LS7s

Each a bargain with amazing sound for what it is..
