I heard the O/93s at Whetstone Audio in Austin, great shop and great owner. It was paired with a Leben CS600 integrated. I listened to some Simone White and Ella Fitzgerald w/ Louis Armstrong on vinyl in a sort of near field setting. It was a great experience, definitely the encompassing wall of sound effect with a lot of boogey. Great tone and bass and I found them very coherent and involving. Wonderful organic sound. I could live with the O93.
On a recent trip to another Devore dealer, his opinion was that the O96s needed more power than a 300b can provide. I found that shocking as that's pretty much the singular low powered tube amp you would want to use to drive the O96s, and the fact that I've read so much about how great it sounded with 300b tubes and the like.
I would assume if you're intent on using the 300b the O96 would be better, and the 845 could easily drive either. If you're using the Line Magnetic 845 monster tank amp, I think either speaker is known to have great synergy with that amp.
