Are you saying everyone with a hifi system requires a room correction facility of some type?I have the impression that you did not read my previous comment about the importance of the influence of the room on the sound, and about the means of correcting these shortcomings
If so you might wonder how brilliant hifi setups worked in the past by simply choosing good components and selecting and positioning the right speakers for the room.
It's how it used to be done and is obviously lost on some people.
You need software to, so called, sort your system that's fine, I will use my experience and ears.....
Software may have its place but ultimately its no panacea, you cannot make a silk purse out of a sows ear, as the saying goes.
