Your guys prefer the concert Bluray in which audio format?
I knew US/EU bluray only comes with one HD format in the disc but most Hong Kong concert BD comes with all 3 of them!!

my rating:-

1. 5.1 LPCM (voices coming from center speaker)
2. Dolby TrueHD (more clarity and the bass are more "true" to me)
3. DTS-Master (if I wanted a more ummpppphh in the bass department, but the voices mostly from L/R speakers but not from center and it can be 96/24 for all channel)
