Devore O/96 with high powered amplifiers

All good points. Part of my speaker choice was to go an entirely different direction and try some designs I’ve only read about. Switching one component at a time results in some mismatches along the way. Bass isn’t the priority, I just noticed a real change that I didn’t expect; too much to be explained by the size of the box. I’ve got the O/96 up on sliders now and moving them around. It's improving the initial bass shy balance, and likely I’m adjusting to the new sound too.

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.

Not an O/96 owner, but I did watch Ken Micallef's interview of John Devore where they discuss John's system. In it John, mentions that some high-powered amps do not like the O/96's high impedance. His example was the change from a long-time Parasound A21 reference to a JC5. The JC5 did not mesh well with the O/96.

The DeVore can do bass nicely but its important to keep in mind the speaker is not designed for a tube amp with a higher damping factor. At shows DeVore is often seen using an SET with no feedback which has a lower damping factor. He is relying on this for the speaker to make bass properly.

This is why some higher powered amps might not be ideal on this speaker. Its not the power that's the issue- its the fact that the speaker is not meant to be heavily damped by the amp.
