Higher output SET or SE tube amp for Daedalus Spea

I have recently bought a pair of Daedalus DA-RMA speakers and wonderful they are too. They are transparent, fast and detailed and a bargain at their price.

After some searching, I found an amp that really matches well with them, the Pathos Inpol2, a 50 watt Class A hybrid integrated. I am more than happy with the Pathos, but hanker after the all tube sound I am used to. So, I would like to find an all tube SET or Single ended tube amp as a change of pace. The speakers are rated down to 8 watts output, having 96db sensitivity. I still think they need 15 watts + if possible to do them justice.

I enjoy all musical genres, Classical, Opera in particular, but blues Jazz, some country and western, some Rock. My room is 20 by 22ft with an 8ft ceiling.
My thoughts so far, including amps I have and have'nt heard, are;
Cary 300Bsei
Almarro 318B
Ayon Orion, Spirit or Mercury
Audio Note Kit 2, based on 6550 tubes(I am minded to try and build my own)

The list is'nt exclusive, all advice welcome. Thanks
