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.
MAGICO M6 hang on for NOW.
Vandersteen Quatro's will most probably be my last set of speakers. I can't afford anything more and the Quatro CT's bass set up is NEEDED in my room as it's difficult.  Best sounding speaker I've had in the house to date.  Wish I could afford the new Kénto's, lol....
ANY correctly refurbished Ohm F .... 
Bought my Walsh 4's in 1986 they were a store demo (1984 build).  Sold my Infinity Monitor Jr.'s  which I had purchased in 1977.  Currently scratching my head as to whether I should just re-foam them one more time or trade the cans in for a Walsh 3000 series 'upgrade'.
Mine'r almost 30 years old.  They've been in my room for a mere nine.

No itch to change out.
