Great to hear of your success, but it would be nice to know which tube preamp you are comparing with the MAP-1. I too am thinking about a MAP-1 but it is hard to imagine it bringing on the magic of a tube preamp like my BAT 31SE or previously owned, ARC LS5 III. Some tube preamps are absolutely phenomenol and others are downright terrible so knowing which model you are talking about would give the readers here a reference point.
