In my case, it doesn't matter which source I'm running (TV, music server, or Blu-Ray) my 68 applies the music setting (Trifield). Is the HD621 transforming all these signals to 24/96? If so, why would it do that? Is that the highest resolution that the 68 handles? Is there any way I can tell what signal the 68 is receiving?

Thanks for any help. [/quote]

If set up that way , HD621 will upsample sources to 88.2/96khz . If your Bluray is outputting 5.1 it should normally select Cinema preset ( Discrete at worst ) .

See manual page 6 :

" Up/downsampling of digital audio

The MMHR and SmartLink outputs can be set to deliver either standard (44.1/48 kHz) or high resolution (88.2/96 kHz) sample rate digital audio, with resolution enhancement of up to 24-bit.
When set to standard rates, the output is either 44.1 or 48 kHz irrespective of the input rate, high sample rates being downsampled by a factor of two or four as appropriate. 44.1 and 48 kHz rates are unchanged.

When set to high rates, the output is always either 88.2 or 96 kHz, irrespective of the input rate. Standard sample rates are upsampled by a factor of two using Meridian`s powerful DSP technology, so that input signals of 44.1 and 48 kHz are output at 88.2 and 96 kHz respectively "

Mostly harmless. Comfortably numb.
