If you're listening to Gaucho and it sounds bright, then it's very likely your room in my opinion.

Yes, different strokes for different folks and we all hear differently from each other. Most (though certainly not all) that call Axioms bright are using poorly-recorded material.

But to feel that a well-known, excellent recording sounds bright... I'm really guessing it's your room.
