Conversion Therapy

摘要

It's no exaggeration to say that dCS spearheaded the now current vogue for upsampling to step up the sound quality of the humble compact disc. This may be as much to take advantage of modern DAC silicon which is optimised to work with 'DVD era' PCM digital, centred on a 48kHz baseline sample frequency. But dCS Limited was also at the forefront of DSD technology, and it wasn't long before DSD upsampling appeared as an alternative option within its line-up of converters. Instead of reprocessing CD's 16-bit/44.1kHz datastream into 24/96 or 24/192 PCM form, it could now be upsampled to a 1-bit/2.8224MHz format, and treated like raw DSD from an SACD disc. Not only did the standalone dCS Purcell unit get DSD upsampling added as an option, but so did the original Verdi disc transport. Until this review, I'd never tried DSD upsampling, as I've remained deliriously happy with 24/192 upsampling from the Purcell over a 'dual AES' connection.
