@inna Yes, the Lamm hybrids I own use a 6922 in the driver stage.
It always boils down to the right tool for the right job. Lamm's low powered SET amps are remarkable with horns and other high sensitivity speakers, while the hybrids are a perfect match with difficult loads like my vintage Sound Lab electrostatics.
Generally speaking, I'm inclined to prefer tube amps, but the Lamms do what many tube amps can't with difficult loads. They also beat my BAT VK150SE monos even when driving easier loss like Nolas. It's nice to have amps that are likely to work well with any speakers I might choose to purchase. Cheers,
Spencer
