Look, if it's genuinely well made internally and uses a quality transport mechanism, it's pretty good value for money for a statement CD/SACD player. The top machines have never been cheap.
My TOTL players from Sony cost nearly $3k, 32 years ago and the best Marantz in my collection was $6k in 1991. Those machines all still function and test perfectly due to their absolute battleship build quality. So 40 pounds (18kg) may mean some thick steel plates to add weight and it may mean uncompromising componentry and build, attention to detail and hopefully (in this case for the reviewed Marantz) longevity.
