Myself I'm a OPPO or Marantz person. If I had to replace my current player It sure would be a very hard decision, and I might just get both. The OPPO because it can play SACD's, they are still supported as @Sk1Bum mentioned, and other reasons, and then a new Marantz because it has a warranty and it will easily integrate into my new Marantz AV unit.
I also like having the ability to introduce a separate DAC unit. This might give me the ability to upgrade the DAC with a newer unit in the future.
Prior to the purchase would be a trip to my local store for an audition of the unit in question.
A purchase for me might look like this,
OPPO BDP-105D or other similar models
or
Marantz CD6007
Along with an separate DAC
Maybe a Schitt Modi 5
Good luck on your search for a replacement!!
