Matthew,
I'd assumed that the 950 was capable of handling a 96 kHz signal.
It is. In fact it's even capable of handling a 192kHz signal.
In this era of multi-gigahertz processors, I'm not sure why any piece of equipment would be unable to handle a 96 kHz signal.
Surround processing of a stereo 96kHz signal can seriously tax the processing chip; that's a helluva lot of data to manipulate! When your 950 or my old MC-1 does D/A conversion of a 96kHz signal, they are essentially bypassing the processing chip (no data manipulation) and going straight for the DACs.
What's the point of using expensive 192 kHz DACs, anyway, if nothing better than a 48 kHz signal ever gets to them?
Who says that nothing better than a 48kHz signal ever gets to the DACs? Surroundophile had no problem with the data from his DADs being passed
digitally to the 950's DACs; it even switched over to the 96kHz PCM Stereo mode automatically. And because there is stereo 96/24 software that can be digitally fed to processors, it makes sense to have 96/24 D to A conversion built in to the 950.
Also, have you tried to find a manufacturer that still makes 48kHz DACs? Pretty soon every receiver and processor will have 192/24 capable DACs in them, primarily because that's all that will be available from chip makers. It's like when someone asks if it is worth getting a DVD player that passes DTS or has 96/24 DACs built in. Let's face it, it would actually require extra effort (not to mention some additional expense probably) to find a DVD player
without those features.
Best,
Sanjay
