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!
awooof
For me the consideration mainly is will it have enough to drive my speakers.  If 2170 can drive Dynaudio C2 without any issues (can it?) would there be any advantages to 3400?
I've got Klipsch RF 7ii but likely trade in for PSB T-3's when my lottery numbers work out!
