3/5 enough
  by Richard Torbo (Miami, FL)
The ear can not hear over 25-30KHz, therefore 60-70KHz would be ideal. Unfortunately there is no 65KHz standard, but 88.2KHz or even 96KHz is not too far from the optimal rate. 192KHz is way off the mark. It brings about higher distortions, bigger data files, increased processing costs, and all that for no up side! People that think that more samples are better, and that digital is only an approximation, do not understand the fundamentals of digital audio.

5/5 The Nordic Sound - 2L audiophile reference recordings
  by Hai-uy Dang (Fountain Valley, ca United States)
In order to provide the right context to my review of this outstanding Music-only Blu ray disc I think its important that people have the right equipment that can actually output the full audio qualities that the producers of this album intented in order to experience the magic of this recording. My review is for the Blu-ray disc and not the SACD disc also include. First, you will need a capable blu ray player and receiver that can decode 192khz/24-bit DAC's for all channels, this is important as this Blu ray has both 5.1 DTS HD MA 24/192kHz 5.1 LPCM 24/192kHz soundtracks, I actually prefer the 5.1 LPCM to DTS HD MA as the bit rate was constant at 27 mbits almost for LPCM, almost twice the rate for the DTS audio and you could tell it provided a more enveloping sound field IMO. This recording also gave you a good selection of different recordings, some originally recorded with Original source: DXD (352.8kHz/24bit) before mixing to 24/192kHz taking full advantage of the maximum audio capabilities currently available today. For comparison, regular CD's are recorded at 44.1 kHz/16-bit rates with only 2 channels. Overall, the recent recordings from 2L released on this music only Blu ray format is really exciting and rewarding for those that care about sound quality and this type of music. It really gives you that true in concert feeling without being there.

My equipment:
Blu ray player:PS3 outputting LPCM
Receiver: Integra DTR 7.8 with 192/24 Burr Brown DAC's for all channels
AMP: B&K reference 200.2 watt 2 channel amp for front L/R speakers
Speakers: Martin Logan Source Front L/R, B&W CC6 center, Martin Logan Ticket Rears, Martin Logan Dynamo Sub
