That's cool! If you try, let us know if you like better sacd via hdmi to bda3 or directly from the marantz which is a good player.
I don't use upsampling, i prefer to leave the signal as it is
I will let you know, u bet
! I really, really hope that SACD via HDMI to BDA-3 is better, far better, than directly from Marantz UD7007. There is nothing wrong with Marantz though, still I have high expectations on a separate DAC:s performance, due to its main purpose, as I see it.
As for the upsampling, I will at least try it with different recordings. I want the music/sound to be as "neutral" as possible.
