Mark, are you sure you had no expectation bias, or was it merely that you expected to have none? <UD

Perhaps oddly, sometimes it makes much more of a difference than it should. In some cases I have suspected RFI sensitivity of a circuit out on the bench might account for some of it. Some confirmation of that simply by dropping a circuit down inside an empty steel computer case laying on its side. The cases can be reasonably lossy at RF.

I did have expectation of no difference, as I said. We have the word expectation for such situations. However, less clear we have the term 'expectation bias' defined as a scientific term. I guess it could be considered as audio forum slang.
