Yea Mr Guttenburg did not have time to get set up right or could have been listening for the wrong center location if not a solid center image. That’s an Ohm strength. Mine is rock solid center of wall, but not center between speakers. That’s another omni difference. Mono recordings never sounded better so I am able to enjoy any recording from any era: a music lover’s dream. Good mono recordings are anchored dead center but with ambience that actually still provides a lifelike sound stage but with players dead center.
On a related note, not to confuse things but my Ohm100s run off the Bel Canto c5i actually sound more like GP in the highs to me these days than my 5s. They both have same generation walsh drivers just different size. The difference is the integrated amp. I’ve run both of various amps and its the C5i digital integrated amp that does the trick. So all the gear upstream matters a lot and results can vary widely. You hear what you feed the Ohms more so than just the speaker itself.
