I own the SACD 30n. To me worth every penny, top notch CD player, streamer and Dac, this unit does not use a traditional dac , it uses Marantz's own design by Ken Ishiwata, converting all inputs from pcm to dsd, using 2 clocks 44.1 and 48khz. that converted dsd file is sent to the hdam output board for processing, the sound is just clean wonderful sounding music no matter the source. Build quality is outstanding on this unit, The oled screen is just stunning , I can read it across the other side of my room, nice big lettering I could hardly lift the thing from the box it weighs like an amp would, people will be surprised at the build quality of this unit I was !! I knew it would be good but away beyond my expectations, the remote control is even better quality than my KI ruby remote and that is superb , it is heavy and top half is metal build everything feels and sounds top notch, the sound from networking is really good, I use tidal via audirvana and the sound is just superb, you have digital outs being optical and coaxial as well as 2 optical, usb, coaxial inputs , fixed or variable rca out, the Heos app works very well, you have access to most of the music streaming services, the tune in radio is very good , the best sound quality is of course from sacd, just top notch, big upfront presentation, the standard cd sound is also top notch to my ears, with superb clarity and dynamics, it sounds sublime through my KI Ruby amp and my Tannoy D700 speakers, I can highly recommend if you want an all in one solution.
