Do consider that if you just buy the Marantz new, you're done and up to date (for what THAT'S worth). Life is short. I've regularly seen 30+ % discounts online for the more desireable Marantz pieces, which might just end up looking pretty good $-wise vs. used, particularly if you really think through a projected resale scenario for down the road. Consistently reported to sound "warm", "musical", and simply pleasing for long term comfort, the better Marantz models do seem to have a place in a home which also contains gear with more inflated ambitions. Maybe that's all you really need for this application.
