In my system, Luxamn M800a amps sound extremely close to vac phi300.1 in many aspects including the sense of space. I used different preamps and results are similar. I tried Pass, Classe, ML, Rowland, Boulder and these have their own strength but none mimic the tube sound like the Luxman.
IMHO, some SS amps can sound close to modern sounding kt88 or 6550 type tube amps operating in ultralinear or pentode mode. When I had the Vac in triode mode, the delicacy improves further and pulls away slightly from the Luxman in inner detail.
I doubt there is a SS amp that sound similar to the best of SET or OTLs when driving suitable speakers.
