In Whose Ears Do You Trust Most?

Ok, so I've been an audiophile for 30 years or so, I've heard a lot of equipment, and I think I can analyze sounds and express what I hear in words pretty well, but still, when it comes down to it, I don't feel 100% about what I think I'm hearing till my non-audiophile, equipment agnostic, music loving significant other tells me what she hears, how it compares, etc. I'm always a tiny bit afraid that I hear what I think I will hear (I think Roger Modjeski called it the Heathrow Effect) - don't know if you had that feeling. I trust her her naive, indifferent assesment of equipment to keep me honest. You?
