Think so many people miss the point of vintage gear. Audio brings emotion. Marantz is as much art/decor as sound. Many people are building up system that attain a certain look, with sound being a byproduct.
yes, lots of new things might sound better, but they look like poop.
I would rather have a vintage Marantz for $600 then something new. Nothing sounds as good as my vintage setup for the price. Plus Marantz has a certain sound that some just love, much like Mcintosh.
