Looks like my Dtps. (Doritaenopsis) Chingruey's Goldstaff
See the thread the Phal Abuse Ends Here, lots of good info there. (Dtps. is a Phalaenopsis really, it's a genus name that is no longer being used as they are genetically the same as Phals.)
Not saying with certainty that it is the same as mine - if it did not come with a tag than it is considered a NoID - but very close. Yours does appear to be a miniature while mine is a 'compact' plant. I have another plant with the same name but it is a mini and looks different.
