I'm about to take possession of Omega Super Alnico Monitor speakers to match with my UFO25th Anniversary amp. I'm looking forward to all of the purported aural qualities I should expect with this speaker amp combo. Having said that, Yet, I'm wondering if I should add a ZBOX to the mix in order to compensate for the lack of low end heft that others have cited with this particular set up. Any thoughts? PS, I have Rel subwoofer in storage that I can also add to the set-up, or not.
