I like the -3db adjustment. It has the same impact to my ears as the -10 and I try as a general rule to make the smallest adjustment as possible to make an audible difference.
I will be trying the L/R specific recommendation over the next few days. Thanks again, I really appreciate the suggestions.
By the way when you change a value in a filter by using the slider in MiniDSP, you have to release the mouse button before the change is applied.
Maybe that’s why they sound the same? Just felt like mentioning it.
