@cruxarche, Kudos to you for acquiring a system like that at such a young age. Until recently, I was using a Sony AV receiver, Jensen speakers and a Pioneer CD changer, all 25-30+ years old. They still sounded pretty good to me, but at this advanced age (65) I decided to treat myself to entry level audiophile equipment. My nephew now uses my old system and is happy with it.
Along with the advantages noted of newer equipment, I have seen people on this forum and elsewhere state that the quality of equipment has declined the past 20 years. Unless you are paying big bucks, corners are cut to reach a price point. For that reason, some people seek out vintage equipment and then have it checked by a qualified technician for recapping or what replacement is deemed necessary. If, as you say, funds are limited, you might need to be frugal in trying to upgrade your sound (I have no idea what restoration of vintage equipment costs, but people do it. I recommend videos by a guy on YouTube that does excellent work — xraytonyb. Check it out).
