F.I.M. and JVC Debut New XRCD Technology – Many readers will probably be familiar with JVC’s enhancement of the original xrcd disc format introducing 24-bit processing: xrcd24. Now a new super-mastering format has been developed, called K2 HD. This hi-def technology takes in 192KHz data at a bandwidth of up to 100KHz. Marked improvements in harmonics, presence and dynamics are realized. The first three K2 HD xrcds will be issued by First Impression Music in 60 days, and all future xrcd releases will use the new format. By the way, JVC’s own label xrcds are once again available via Elusive Disc distributors. We expect to return to reviewing them at Audiophile Audition soon as well.
Improved DSD Technology Now In Use – DSD is the audio standard recording format used in the production of SACDs, but it requires special editing gear such as Sony’s Sonoma workstation. Digital eXtreme Definition (DXD) was developed so that the hi-res masters could be edited on PCM editing equipment. In the process the professional audio format, which has a PCM-like 32-bit floating point, samples at four times the sampling frequency of DSD and eight times the frequency of Red Book CDs. The data rate is 11.2896 Mbit/s. DXD provides the ultimate in analog audio qualities and leaves extra headroom for editing and balancing before the signals are quantized to DSD for final production of the SACD. DXD is used in the Pyramix DSD workstation, which is currently used by several SACD labels, including 2L, Caro Mitis and PentaTone.
