Any Camelot Arthur Owners out there?

I'm not concerned about the ability to pass multichannel signals to the Arthur - this is strictly for 2 channel playback. My DVD player downsamples to 48khz at the digital out if I set it to do so, and the Arthur will process it. So perhaps a DIP will work, provided it will not have the issues they used to have with not locking on to a signal for the first few seconds of a song.

Let me ask this - I am primarily using the DAC for playback of music DVDs, Diana Krall, Nora Jones, Sting, etc. I don't buy any DTS DVDs. I'm running all of this in to a SF Line 1 SE and Threshold amp. Strictly 2 Channel. I've watched numerous movies in 2 channel using the DAC with no problem. But what is AC3? Isn't that an LD format?

Thanks again!
