There is one aspect of this that is a new experience for me. I previously had equipment that had basic tone controls and a manually adjustable graphic eq for low frequencies that gave some control over room modes with a db meter and some tweaking time.
But now with a brand new Emotiva MR1L processor with parametric eq in the mix and this so called automatic room correction I listen to the results of the auto eq and it sounds awful. I have gone back and removed all the eq and done some manual adjustments with PEQ and like the sound much better. It still needs tweaking more but there is so much range of adjustability and in such fine detail it makes making any changes unwieldy and awkward. I would prefer, I think, standard treble and bass controls with PEQ below 100 hz. Some people I think really get off on eequipment with a very high fiddle factor. Me, not so much. I want adjustments but for God's sake make them easier and more effective to use...
