Thank you for the additional info.
First, if you click on your UserID… a couple times you will eventually find, “create a virtual system”. If you get their it becomes easy. Easy to post photos and ID your system.
I looked up the components you have. I assume if you are on a fixed income that means you are retired. My initial conclusion is to take your time. Look very carefully at all your components before moving forward.
If carefully considered, one can make great improvements with $2.5K… and even greater in a year or two. But, to do this a very careful strategy is required. We will have to make sure the components you are considering will move you towards the sound you like.
Typically, one would have about 35% of your investment in speakers. Having two sets just dilutes the effectiveness. Also, combining with an AV Processor will degrade the sound. All of these things need be considered to move forward efficiently.
If we can see your current system / venue, this will help a lot. I am also happy to discuss privately via private message.
