One thing I notice about Shahinian versus OHM is Shahinian has a forward firing woofer I believe. The OHM Walsh driver fires downward. A forward firing driver might impart more low end impact that can be felt to a listener sitting in front than a downward firing in that more sound reaches the listener directly, all other factors aside.
This difference in the presenation of OHm Walsh speakers is something that people should be aware of and I believes help drive the need for higher power amps. Those who are used to speaker or subwoofer drivers firing directly at them might be put off by a seeming lack of impact by the Walsh drivers in comparison. A smaller percentage of the sound produced reaches your ears directly with the OHMS or even other mostly omni designs, like mbl. Once you feed these enough power to really energize the entire room (not just your listening position), things start to really shape up.
