Well I've only been listening for about an hour, but it's actually not that dissimilar to the ?22. Really nice bass. There's definitely a nice weight to it, but it's very controlled. I'm certainly not familiar enough with the Omegas to go into much detail yet, but there's no doubt that there's a tube in the preamp output. Very organic and slightly warm sound, without being too lush or gooey. I'd call it a bit warmer than the ?22 which is very neutral.
