converted to the sampling rate of 48 kHz.
96KHz
Select this to play back discs recorded at the sampling rate
of 96 kHz. If the 96 kHz disc is copy protected, the digital
output is automatically converted to a sampling rate of 48
kHz.
I suspect this setting is simply used to limit the sample rate to what the receiver or amp can handle. As I suggested earlier, you're probably only going to let the Nova decode cds, which are 44.1kHz. So either setting will probably yield the same results.
That said, I suppose it wouldn't hurt to audition 96kHz DVD-D audio to the Nova, but if it's protected it will be downsampled to 48kHz and likely won't sound as good as the analog signal to the Nova. Then it will be a matter of knowing what's downsampled and what isn't. Probably easier to let the player handle it unless the auditions make it obvious that you want the Nova to do the conversion. I'd be surprised if that's your conclusion.

You are correct. The Nova is two channel and needs to see a 2 channel LPCM signal.

I'd be surprised if this is true, but if you are connected only to the Nova, 2 channel is all you get. For the most part, 2 channel is much cooler anyway.

This will be something next week or later, because the Nova is at the dealer's office and he is waiting for the Era D5 to arrive sometime next week so I can pick them all together. I bought this player because It also support SACD playback so I am going to test that with a Hybrid SACD to see if I can hear any difference.
The Nova has a really nice DAC, but if the CD layer sounds better converted by the DAC in the Nova than the SACD layer decoded by your player, you might want to rethink your new player. I think you're going to find the sound of the SACD layer to be richer, less truncated, and more organic. It'll still benefit from the quality of the preamp and amp in the Nova however. You should enjoy a nice listening experience that only gets better over time.
FWIW I'm using all analog and all digital outputs from my player. They all get used. It's easy to do an A/B comparison. I've concluded that letting the player handle the hi rez material, and letting the Nova upsample the low rez material (including redbook cd) renders the most pleasing results.
