I have asked a similar question on another forum and lots of people say a blu-ray will be fine and will play sacds and dvds as well, even a cheap Sony like the 490 will play them and even 3D DVDs if you want, make sure it has optical output. The Sony is only £80.
A £60 LG BD player from Curry's will still play CDs but the audio won't be in the same street as the Marantz CD player without an external DAC. Also I'm pretty sure just any random blu ray player can't play SA CDs (but yes the Sony does)
Main gear: Mac Mini > HRT Streamer II+ > Marantz PM66 KI > Mission 794
Also cluttering-up the place:
Thorens TD160 no cartridge; Marantz CD63 mkII KI; Technics SL-P777; Cyrus 2 + PSX; Cyrus Tuner; Nakamichi DR-1
DVD Players normally use switching power supply circuits while almost all CDPs use transformers (or toroidal Transformer on better ones) for power supply. The problem of using switching power supply is its noise and it will affect the qulaity of the audio and digital outputs.
