Amp/Integrated Amp Pairing with Alta Alyssa Speakers

I would appreciate any suggestions on an amp or integrated amp that would  partner well with Alta Audio Alyssa speakers.  Current setup is Schiit Freya+ and x2 Aegir monos with Zu DWX.  Just received new Alta’s which need a bit more oomph and I’ve been considering an amp like the Orchard Audio Starkrimson in combo with my Schiit Frey+ or going single box with a Heaven 11 Billie mk3 (not sure which power core?!?), Bel Canto, Hegel H390, Eversolo RA280, etc… I am currently auditioning a friend’s Heaven 11 Billie mk2 with the Alta’s and enjoying the pairing - maybe a tad more detail would be nice but not a deal killer.

Thanks in advance for your thoughts!
