I can't compare the Nola speakers to the Paradigm speakers, never heard the Paradigms, but the Nola Boxers are remarkably satisfying speakers and one of the best bargains I've ever found in decades of buying and swapping out components.
They replaced a pair of $4K floorstanders in my system from one of the most highly regarded speaker designers around. And, while I might have lost a slight amount of resolution throughout, the Boxers have better bass and are at least as enjoyable to listen to. Mine are the original Boxers, not the Boxer 2. My only interest in a speaker change now is to upgrade to the Boxer 2.
