the guy I bought my o93’s from said he thought the o96 was 10 percent better than the o93. That’s his experience. He also said the bass was more pronounced as well as the tone sounded more real.
That too is a very valid summation. Art Dudley and Tom Gillette (aka Sam Telling) seemed to prefer the O/93's. Besides the slight discontinuity/wrinkle in the midrange, the O/93's have a tendency to sound wide, high, but flat (lack of depth) that the O/93's don't have (there is depth of field to the O/96's).
I have reached the age and point in life where I am done chasing for something better. At some point for any given person there really is no better-just different. I love the O/93's. I bought a pair of Spendor D7.2's brand new from Galen Carol about two years after buying the O/93's and regret that purchase. They do little wrong but just don't make me smile. I also have a pair of original B&W 805 Matrix that bought new way back in early oughts and I had modified with better crossover caps and internal wiring by John of Van L Speakerworks in Chicago and I really need to pull them out and give them a turn. Imho, there is something magical about those speakers that only got worse and not better in subsequent iterations.
