The DVD side includes PCM versions of 9 Album title in only 48kHz / 16bit resolution. Accordingly, no more tonal gain over the standard CD can be observed. Mehrkanalmixe are not included. The possibilities of the DVD are therefore not even exploited to some extent. So the DualDisc is not a success. The two (bonus) duets from "One Voice" are also 48kHz / 16bit PCM versions. But we are waiting for the publication of this concert in its full length.
