Devore O/96 with high powered amplifiers

The Devore O/96 arrived and are now set up exactly where the previous speakers were.  First impressions indicate there is work to do with placement.  I was expecting strong bass, especially with the high powered amps; however, this is not the case.  I appreciate the detail, midrange, and liveliness, but improvements are needed.

Looking at your virtual system it is curious that you went from Wilsons to the Orangutan 96 if strong bass was your priority. There are always trade-offs regardless of price. With that in mind you went to a smaller, simpler loudspeaker that does not push as much air as the Wilsons. The O/96's are not bass monsters. They are mostly about touch and tone, with a very distinct sense of refinement and propulsive-ness. This can go two ways imho. You may be the wrong customer for the O/96's or you may with time grow to love them for their good qualities. That single 10" SEAS driver can go fairly low with moderately taut bass but it will not thump you in the chest no matter how many watts your throw at it. 

Sorry to keep droning on but look at it this way-compared to a pair of Falcon Gold Badges the O/96's have extended bass and good low-end grunt but compared to refrigerator sized Wilsons they do not. 

I mentioned touch and tone. I believe that a good 30 watt tubed amp like the Leben is pretty much the sweet spot for drawing out the best qualities of the O/96 that MAY, if you are the matching type of customer/owner, get drawn in over time. 

And last, for reasons unknown Auditorium 23 speaker cables are a magical match for the Orangutans. 

The best amps I have heard on this speaker were the Atma-sphere OTLs. Can be a bit ruthless but this DeVore errs on the forgiving side of things.

The Atma-Sphere OTL is a good suggestion.  I've read that they are a good match with O/96.
