Best integrated tube amp for Audiophysic Virgo 3?

Yes I would prefer integrateds, it funny that the dealers say a small tube integrated amp will work well with this pair. They said old good integrated as will should be included *
I am looking at a 50 watt tube amp and one that is not from the far east(even thought they make good stuff).

I am actually using this is a fairly small room, kind of close and toed well as suggested by Audiophysic and getting good results with a hybrid but prefer lush and warmth for this system.
