Hey david_ten,
If you have not read my review on HTR on Tekton's very innovative Sigma OB speaker, which is an absolutely wonderful sounding speaker, and I gave a PRODUCT OF A YEAR AWARD, to get the details how Eric figured out how to avoid any electrical EQ to get the bass frequencies right. I love planar speakers sound-staging except for how they sometimes enlarge individual images and lack focus in location on the sound-stage and how OB designs can create a planar like sound-stage without these difficulties.
However, I believe the DI's do everything an OB design can do plus many more virtues that are talked about on this thread.
