It appears that your Olympica Nova V's can be bi-amped. You might want to start by trying that to see if that adds enough low end to your rock recordings. Integration would be far simpler. Separate gain control with each amp would be required for best results. Without it there might not be a noticeable difference.
Subwoofer with Floorstanding Speakers?
Still enjoying my Sonus Faber Olympica Nova Vs in our den where I mostly listen to jazz. However…I had a nostalgic experience tonight and streamed up some Def Leppard and cranked it LOUD. With this kind of rock, I am missing a little of the bass I remember from my school days. Got me thinking, how many of y’all are running a subwoofer in your stereo setup with floorstanding speakers? What do you think? Any issues with sound distortion?
