First HIFI system

Seperate sub????
Don't you mean FOUR subS?

Maybe you are right. I can't say. But I DO know that there is a t least one generation that listen to Mp3's and think they sound good. Some musicians I have played music with, think 128mbps is CD quality. Since the vinyl resurgence, 've seen a lot of people say that a VG record sounds fine. I can't tell you how many times I see people  listening to music on their phone's pin head size speaker. When offered a Bluetooth speaker, they say, Nah, it's fine.

So I often wonder what modern society believes good sound  is? I've seen too many of the above actions to trust they do. Obviously there are exceptions in both equipment and people.

op

you asked for feedback... regrets?? 

🥴

Probably more confused than regretful. Welcome to the worlds most cynical audio forum where opinions are facts. 

Thanks to everyone for the quick response and feedback, that is a lot to digest. I do understand everybody point of view, but let me explain mine. I'm limited on speaker placement due to the layout of the room, I know, I should have placed my furniture after the HIFI and not the other way around. For example I only have a niche of 22" by 22" for my left speaker and a maximum of 80" to keep speakers apart. I'll probably have to pull that one out from the niche if I crank that volume up just for it to have space to breathe. 
I'm not a sound purist or have the knowledge to understand it but I do listen to music more than i watch TV and for that reason sound quality is important. We've been listening to music from a compact stereo with two book self speakers on a tiny room and just by moving this compact stereo to a new house with enough space for sound to propagate put a smile on everybody face. I'm looking to get something that can give me a better sound experience but within the same use scope we have used the old stereo with music streaming and occasional CD listening.
The idea for an all in one system besides $ saving is the convenience of having only one piece of equipment and with the constant equipment evolution easier to replace/upgrade once i start having a better understanding of what is important to me sound wise, which is going to take time and mistakes.
My budget is not limited but I don't wanna go crazy buying something that I don't have the space or the sensibility to fully enjoy since we mostly listen to music while we're doing stuff around the space and not sitting down at an optimal distance being engulfed by that music that gives us the chills. Hopefully this initial systems will open the Pandora box for the search and need of that experience.
I live in the Azores islands so used equipment is not an option cause there's none to choose without having to get on a plane to go listen to it and same said on what's available locally for me to purchase.
