Does this system seem ok?

Sprout100
ELAC Uni-Fi UF5
ELAC Debut 2.0 DS10.2 Powered Sub

Will be used for music, 50/50 between vinyl and Bluetooth. Mostly a wide variety of rock music, but plenty of other genres as well.

The Andrew Jones designed Elac speakers are notoriously inefficient and the UF5’s are no exception at 83db for 1 watt. That coupled with their dip into the 3 ohm range would put a lot of stress on the Sprout. Wouldn’t be my choice but you can try it I guess.
