question regarding listening to bluray concerts in stereo

I prefer to listen to some of my bluray concert disc in stereo. In general should I select Lpcm stereo on the disc menu or is it ok to select dts master audio and just select to play that in 2 channel on my processor? I've tried it both ways and to me selecting hd master audio on the disc menu and then selecting stereo on my receiver sounds better. I'm not sure why that would be. Both lpcm and master audio are losless right? Any feedback would be greatly appreciated!

With DTS (or Dolby) multichannel the multichannel signal must be recombined (folded) into 2 channel. There is metadata to do this process but it does require reliance on (maybe somewhat subjective) algorithms and extra DSP. LPCM 2 channel doesn't require this.

The following are some of several possibilities:

1) Different masters used for LPCM and DTS mixes

2) Different attenuation levels for the DTS and LPCM encoded on the BD

3) Better perception of a quality doesn't always correlate to a more accurate reproduction

4) Receiver setup with different DSP settings for a DTS vs LPCM signal

And (3) above is something that everyone forgets. We all like to say that we prefer the most accurate reproduction from our systems - but MANY of us contradict this in the choices we make in our actual listening preferences. It would be nice if we were all better at understanding what our true preferences are and were willing to express them accurately as a result. Of course, this applies to our entire lives. We are generally all REALLY bad at this.
