Amps in the same class as Pass XA.5 series


I've read a lot of posts saying that the Pass XA.5 is the best amp the poster has heard. What are some other amps that are in the same league?

I would love to see comparisons of the XA.5 series versus the Gryphon Antileon Signature or the Colosseum. Maybe it'll have to be up to me to do that since I don't see many Gryphon owners here.
Everyone is listing SS amps. I have owned a couple of Pass amps and really enjoyed them but I am now driving my speakers with a really good tube amp and would have a hard time going back to SS. If you are open to tube amps there are numerous choices that will qualify for best of category.
A couple of others you might want to compare with the Pass amps include the Lamm M1.2 Reference (110wpc) and M2.2 (220wpc), both of which are monoblock hybrids with a single 6922 tube per amp in the input stage; or the Clayton M200 or M300 (monoblock SS amps with 200 and 300 wpc, respectively). The Lamms and Claytons run fully in Class A and double their power into 4 ohms. The Lamms have a bias switch for system matching, and the Clayton M300's have a bias switch so the amps can run cooler when idling, or when critical listening is not necessary.
