^^Love the techno-babble gentlemen...
Well I am hoping Jim ends up with your Para...if it fits in with his overall plan.
Back to our vintage discussion for a moment George, Marantz is still well loved to this day by many fans, there are quite a few specialty shops who will upgrade them and even considering the cost is about $4-500 people are willing to spend it because they just can't find the equivalent in today's equipment.
One reason I always preferred Yamaha, they had the best phono-stage of the lot from my personal experience, even the built in MC Head Amp performed very well and almost all their gear had 'pre-out's on the back panel so you could always get a more powerful amp later but keep the pre-amp functions. To this day I regretted selling my old CA-1010 when I bought my Bryston 4B...but I have one now and all feels right in the musical universe again.
We've talked about Sony before, even back in the day I never bothered with their equipment other than looking at their cassette decks, a handful of those were excellent. Like you I've never seen a Nakamichi amp/receiver except on vintage sites, heck I didn't even realize they made anything but tape decks.
