The best way, IMO, to build a really fine audio system is to completely ignore the nonsense from peddlers, self-aggrandizing poseurs, and self-proclaimed audiophiles about what "Hi-end" means, and what is the minimum $$$ outlay required to reach that exalted plane of existence. Sample gear, listen for yourself, and find the gear that speaks to you. Learn some acoustic and treat your room. And forget about what anyone else thinks.
I think you'll find that you can build a far better system, at a far more reasonable price, today (well, when the supply chain gets unfutzed) than in years past. So if you want "Hi End, sniff, sniff," yeah it's going up. If you want high quality gear and great sound, you have far more to choose from now than 50 years ago when I started out, with a much greater value/$$$ ratio.
Sorry, didn't mean to interrupt the financial one upmanship, carry on...
