I agree with Jazzman. Go for a DAC first. You can use the Yamaha as both SACD and digital out to the DAC. If you go hard core on SACDs then upgrade later. A single player should make your wife happy with the "mess".
I have a 105 for SACD/DVD-A and use the digital outputs to my Chord Hugo. The Chord is a huge improvement on CD's and 2 track from hybrid SACDs. It'a actually really simple to use one player to two inputs on your pre-amp.
You need to try the Yamaha to your Schiit already. I'll bet the NAD starts collecting dust (not because it's bad, just because it's not necessary).
