Yes once you integrate the Subwoofer in Stereo adequately, then there's no going back! Everything is never going to be the same again. Bass frequency provides a low reference point for ears and every other frequency sounds different with the subwoofer.The sub (and a new pre/pwr chain) has given a new lease of life to bands I used to love when I was a younger man.
Visited @sound_cycle house today for listening to Magnepen and Rel Set up. It was pretty amazing experience with a quick response subwoofer which matched magnepen quite seamlessly... Hardly 10-15% sub volume level was used, but when you switch the sub off it's totally missed!
