Try Meitner gear transport CSDC plus DAC6 (mutilchannel) or DCC2 (2 channel DAC + pre-amp). Though u have specified one box solutions the combined cost is not out of whack compared to some of the pricer one box players like Burmester, mbl etc..even cheaper. The DCC2 also has by pass mode if you wish ( I use the preamp, very neutral). This set up play SACD and will also convert PCM (CD) to DSD but no DVD-A Incredible transparency, extended highs, decays that linger in your mind, excellent transients, clear mid range, image depth excellent. I have compared it to the DV-50, no contest. But admit no experience in the Sony Mod versions (pre-mod Sony definetely inferior) or the X01.
