@goducks44 , can you ever be satisfied? Yes, absolutely. The problem is that you have to know what you like and how to get there without spinning your wheels.
If you are unhappy with the sound of your system it is far more than likely that you are unhappy with your speakers and room. While electronics particularly amplifiers do make a difference they are at best 10% of the show.
Before you spend more money you need to find all the dealers near you and listen to as many speakers as you can. Shows will be starting up again. Do your research and take your time. Good speakers will last you a life time. Do not shy away from listening to very expensive systems. You have to have points of reference. Listen to all types of speakers, horns and planars. point source and line source. If you have any small clubs near you go listen to live music, another point of reference.
Once you have the right speakers you have to deal with the room in the context of those loudspeakers. If you want to be scientific about it get one of these so you can see what you have to do and measure the results.
