Hi Tom, thanks for your comments about these Blu-ray discs, I too have enjoyed the concert hall in Vienna, the video in this case delivering a different kind of listening experience, using more of our senses to create an extraordinary new way to listen. Seeing the conductor eyes meet with the musicians, the concentration and emotion cannot be appreciated in an audio only version.
Regarding the second program, I too have learned that DTS MasterHD is not quite at home for music as the original LPCM version, set your processor to PCM for playback and compare the two, I think you will find the PCM to be more natural. DTS MasterHD for movie soundtracks is fine, but its equalized to add more bass and mid-range than the original soundtrack, a kind of "wow" factor that works well for special effects but not that great with music. You dont need to listen in DTS MasterHD, the audio standard for Blu-ray is LPCM, even when you choose the DTS MasterHD soundtrack on the disc's set up options. The player converts the soundtrack to PCM for the transmission via HDMI downstream automatically.
Best regards,
Bob
