Meridian equipment leaves everything in the digital domain as long as possible. Even the analog inputs have a ADC so that all processing is done in the digital domain (Vinal purists shudder here) Output can be via the DAC for analog (my setup) or digital for speakers with their own DAC such as Meridians.
I can control when upsampling is applied.

We could write a letter to Meridian explaining that this is an experiment to compare TriField against true 3CH stereo, how it would be conducted, and that you need a MCH setup for the experiment. They will be interested, I'm sure, and they have probably done it a thousand times themselves.I think you'd have to send the equipment back after a while, though...

The current 800 conveys all info (including MCH DVD-A) to the current 861 in digital form. Therefore, comparisons between derived 3 channel (trifield), 3-out-of-5.1 channels and high-rez 2 channel do not require any additional conversions, only different processing in the 861. I have not (yet) done such a directed comparison but I have found, in casual comparisons, that trifield is often preferred to stereo.
If anyone knows of a DVD-A with both MCH and 2CH where the MCH mix uses only the front 3CH this test would be easy to perform (Okay, so I'll have to convince Meridian into upgrading my processor purely for the sake of science ;-). My bet is be on the MCH... I'll post this on a Meridian user forum to see if anyone is interested in running the test.Clarification: the current 500 series also conveys digital information between devices. The 'analog input' comment was to point out that Meridian processes everything in the digital domain therfore requiring ADC on analog input.
