Thanks for the response guys. It kind of confirms what I measured. Whether it is audible on voices, it's hard to tell. I haven't seen any NRC measurements of the VP150. I think it would be interesting to see some. Since Ian got my VP150 back, I don't think I'm going to have him send it back to me. I guess I'll just move on. Now what's interesting is that Ian said in his original response to my query, that no way should I measure the differences I measured. One db is all it should differ out to 45 degrees, way beyond my angle. Now, folks are telling me it's normal to measure these differences.
Chess, if what I'm hearing are the artifacts of pink noise, I wonder why Ian had me send the VP150 back instead of giving me that explanation.
Call me confused. Thanks again, guys.
Tony
