Hi Tom, interesting, I just had a teacher and two students from Concordia College in my shop this afternoon and their comments mirrored yours except they were referring to the 150 hybrid. I have found powercord and cable matching is very important to keep that tenor midrange that I loved with my OTL's. I find when I change any major component in my system that I usally change something else before I settle in. Example:
OTL- Elrod powercords
Hybrid- Shunyata anacondas
The 150's took at least 3 months of usage of 8hrs a day, 7 days a week before they filled in. Michael (Panorama) heard a well broken in 150 vs a new out of the box 150 and the difference is major. He owned the 300's and now like myself is very happy with the 150's. I had the 150 on for 6 months and couldn't be happier.
