When I read the subject line my initial response was I trust my ears. Then I read @hilde45 comment and I reconsidered. I trust my ears and not strictly measurements. However, listening and then taking measurements in my room allowed me to make changes so things sound even better. I agree measurements cannot possibly tell the entire story or even most of it, but in room measurements can be revelatory. They have allowed me to make changes to something that, initially, was pleasing and make it better.
Do you trust your ears more than measurements?
I have a lot of audiophiles that say the ear test is the best. I believe them. Some of us have to do blind tests etc. I’m in the camp of trusting your own ears because no matter how something measures. Is it more pleasing to you with a particular cable, placement tweak etc. What are your thoughts everyone?
