I am building a stereo setup for music, HT is a separate system for the time being. I purchased a pair of Sierra-2's, a Rythmik F12 over the weekend. I have a MusicHall turntable feeding to a phono bridge and that runs into a Rogue Cronus Amplifier.

Is it ok to just run the Sierra-2's from the left/right channel outputs on it and then power the sub through the RCA pre-outs, or do I need to route the audio through the sub to filter out lower levels ?

If I need to filter, is there a recommended product to filter between the amplifier and the speaker, most of the filters I saw on the forum were RCA filters.

Do the Sierra-2's require burn in ? I didn't see many posts on that (a favorite on headphone forums), so I wasn't sure. My coworker that turned me onto the Sierra's said they need a pink noise burn in.

Thanks !
