Just bought 2 "Potinaras", what to do now?

[Tango]

Hi there,

I bought two "Potinaras" some days ago at an orchid exhibition in Budapest, two big beautiful yellow guys in bloom.

What should I do with them now? I think one of them may have bad roots, while the other looks pretty OK (thick silvery roots visible). Both plants have tight pseudobulbs and good light green leaves. The plants came from Taiwan and are tightly packed with old sphagnum in mini black plastic pots. Should I repot them now or should I wait until they grow? I like those huge flowers very much but I would like to do the best for the plant, even if I lose the buds. Advice is welcome!

Thank you very much for your help!

T.
