More serious designed than the previous models, although still no WCK ports. I've heard that it had been compared to the Vivaldi DAC in a private setup (final protoytpe). many stuff at that range are cheaty, but DCS I would say is worth it (if you really into high end) street price is around $18,000. asaik, the X20/p never had been doing this comparison during the production. there'll be a X30 features dual ES9038PRO, a ESS USB interface (in the sense of vs-ing XMOS) and a digital transport/network player. A good CD/SACD transport (CD transport and CD player are not the same thing) will still out perform those PC-sourced/digital players, architecture more advanced. DCS and Chord are both discrete d-s but different, while DCS has less residual noise. a good analog preamp is a must since digital vol reduces the vol while the noise (residual noise, I am not gonna type the residual anymore) remains the same. with analog preamp it reduces the vol and the noise (the noise of source) at the same time. good preamps could have less noise (noise of itself) than any DACs (anyway) so it has advantage.
