Best integrated tube amp for Audiophysic Virgo 3?

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.

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).

You need something with a little power for those speakers. You can find plenty of tube integrateds, but finding one that has the power you need may limit your choices. Does it have to be an integrated? Also, you can probably save money by going with separates.
