The 851C uses audiophile grade components throughout and incorporates our most advanced technologies to ensure it plays music perfectly. Your discs are spun on our own audio-only transport and coupled with our S3 servo to give error-free data retrieval and jitter minimisation. Our ultra-rigid metal construction also ensures components are isolated and free from vibration.
