My next system is going to be my final system, would much rather spend the money on actual music.
Maybe it's just me, but I eventually got to a point where I just thought enough is enough. Trouble is, if you spend your whole life chasing better and better, really even what seems like the dream system now won't be in a couple of years. Plus it saps enjoyment from the system and music by constantly wondering if there is better. Plus a lot of the time 'better' wear's thin pretty quickly. It's a sickness really.
My advice is buy something decent, stick with it and spend the money on physical music media. No point buying gold and all that kind of thing, once music is all but digital, should anything ever happen to it or the internet dies, those CD's, records, tape, whatever the format are going to be worth an absolute fortune.
