If we’re talking bang for the buck, might I suggest Marantz? In my experience you either love the Marantz "house sound" or you don’t.
IMO, warm and well rounded. Has "direct" function that bypasses the Marantz tone controls. Marantz has always been conservative with stated power ratings. I have a pre-owned PM8006 from TMR rated at 70, review tested at 90. It’s been said if you want that "classic" British speaker sound, Marantz and Wharfedale.
Having said that...
IMO, you simply can’t go "wrong" with NAD new/used at any price point. Pre-owned NAD will be next on my second system rack replacing a Marantz PM5005.
