I, too, learned of high end stereo early, and had to give it up while I started my business, so I can commiserate.
I hate to say it, but your equipment is pretty old, and technology has only gotten better. I second Adg's advice and go try to get some listening time on speakers. The Bozak's and ESS were good in their time, but I think you can do better with a more current speaker.
If you are willing to buy used, you can save a lot of coin, and still get a super sounding system.
That's what I did.
