I have been provided conclusive evidence of Duke's (audiokinesis) integrity. Due to my postings on the subject of OB/Dipole subs (particularly the one by GR Research/Rythmik Audio), I was contacted by an Audiogon member concerning their use with planar loudspeakers. I answered his questions, and a few days later received another email from the member, telling me Duke had told him OB/Dipole subs would be a better choice for use with his loudspeakers. How rare is THAT?!
