I would very strongly recommend if you're at the beginning of a system building journey to go out and do some listening. Finding a good dealer who's sound you like is a good way to avoid a lot of sidegrades.
If no dealers are near you maybe hit some audio shows at this level it's worth doing a bit of traveling to hear stuff. And take your time upgradeitits can be a heady condition but the more you know and hear the better decisions you will make.
