Bruckner Symphony No. 5 recorded 2013 by Nikolaus Harnoncourt and the Royal Concertgebouw Orchestra. Although I haven't found any published verification of this, Zoltan Glied (who has always been right in the past) reports that this disc, released 2014, was recorded with 96kHz/24-bit sound sampling and has both stereo and 5.0 dts-HD Master Audio output. Grade: Help!
Thank you Zoltan for the tip on the sound sampling! RCO has recorded other material with 96kHz/24-bit sound sampling. The best example would be their Mahler Symphonies 1-10 in a box set. The performances and sound were commendable. But the video was so bad we wound up with a "D" grade!
