It seems like we're in the same boat, since I'm considering the Elgar+ (or the DAC6e). Currently, I'm leaning toward a device that converts USB to digital (e.g., s/pdif, AES/EBU, or I2S). There's no jitter with USB. I'm pretty sure that USB won't do 24/192, though -- I'll let the Purcell or DAC6e upconvert 44.1. But it seems like the UBS-to-ditgital box could still benefit from a wordclock to eliminate jitter between it and the DAC -- I haven't seen one with a wordclock. Empiral Audio and Hagerman make USB converters.
Soundcards with wordclock input
I've read that if you use a common wordclock between transport and DAC, then you can reduce (eliminate?) jitter. I've seen only one card that has a wordclock input made by Marian. Are there others or others that are better?
Also, is it better to use 1) a soundcard with a wordclock input or 2) a USB device (e.g., Waveterminal)? It seens that you would need a wordclock input in the Waveterminal to eliminate jitter between the Waveterminal and a DAC.
