Is Lyngdorf 3400 worth the extra dollars vs 2170?

In a conundrum here. Almost $3k more for 3400 model. Lots of great reviews on both but price? Ouch!
I've got Klipsch RF 7ii but likely trade in for PSB T-3's when my lottery numbers work out!

Try it first these are love or regret buying based on reviews of largely cinema lovers.
