@Emergingsoul, I am sorry to hear about your condition. That said, you could publish details of your system in a post on this thread. I’m sure it will require a word count less than many of your posts.
As regards the substance of your post, acoustic treatment can take many forms that do not require the use of dedicated treatment devices. But those devices, used appropriately do have an important role to play. I’ve come across many instances of people with expensive systems placed in bad sounding rooms, where their investment in equipment was effectively wasted and where a much more modest system combined with correct room treatment would have sounded better for less expenditure overall.
