Tube amps for Eggleston Andra II

I've noticed some discussion & recommendation for various ssolid state amps for the Andra II - but it seems many do not attempt using tubes with them. I'd like to hear from anyone who has Andras or heard them with tubes & their thoughts. My Wyetech Topaz monos were too weak for them so I went to the Levinson 23.5 but am not a solid state fan. I just borrowed a pair of Sonic Frontiers Power 3s from a cooperative dealer & they work much better than the Levy. My room is 25' x 13' x 8' with the speakers firing down the long side. Cement floor with carpeting & using ARC Ref 3 / PH7 / Jena Labs / Redpoint / Triplanar VII / Dynavector XV1S.
I'm especially interested in anyone who has heard the Andras with Lamm ML1 / Manley Neo 250 or 500 / VTL / CAT.
Any comments would be appreciated.
