Classic Records have begun releasing a series of 192kHz 24-bit ‘HDAD’ discs, the titles use both DVD-Audio and DVD-Video technologies to their fullest to deliver two-channel high-resolution versions of renown performances from artists, as HighFidelityReview.com reports. The Classic Records discs do not use any form of copy protection, so if the replay hardware allows it, even the DVD-Audio 192kHz 24-bit content can be transmitted digitally to an external DAC or processor. Likewise the DVD-Video 96kHz stream, an option more widely supported by DVD players and processors. But just sixty seconds of two-channel 192kHz 24-bit PCM weighs in at almost 66Mb, so even with today’s high speed connections it just isn’t practical to share such high resolution audio via the Internet. The first three titles on the Classic Records ‘HDAD’ roster are Mahler’s 5th Symphony (HDAD-2001), ‘Songs of the Auvergne’ (HDAD-2002) and ‘I Robot’ (HDAD-2003). All three are available from the Classic Records web site priced at $30.
