$4K/pr for KEF LS60 is a great price.
But how often will you be using this $4K setup?
If you’re like me and use the master bedroom system about 0.1% of the time, the living room system 0.9% of the time, and use the HT room 99% of the time, I think anything over $1K is a bit too much to be mostly collecting dust.
But if you’re getting the LS60, that is a great price and I think they will sound great for a secondary system.
