Gryphon Diablo 300 is pretty stellar and worth a listen if you have the opportunity. I was going to “upgrade” my Pass separates to the Diablo until I decided to splurge on Gryphon separates.
The descriptions of Ayre sound above are interesting and a little different from my experience - I find Ayre (at least their integrateds) very incisive and fast, but a bit lean and light in the bass, with a bit of highlighting to leading edges and the upper midrange that makes some things a bit pronounced. I suspect this might be due to the topologies they use that tend to have more 3rd harmonics in the THD. They are definitely quiet though and pull out a lot of detail without sounding bright - really good with warmer speakers like Sonus Faber and Vandersteen, not so much for, say, Magico or Focal IMO.
