Five athletes tested positive for the stimulant bromantan and were disqualified by the IOC, but later reinstated after an appeal to the Court of Arbitration for Sport: swimmers Andrey Korneyev and Nina Zhivanevskaya , Greco-Roman wrestler Zafar Guliyev and sprinter Marina Trandenkova , all from Russia, and the Lithuanian track cyclist Rita Razmaitė . Dr. Vitaly Slionssarenko, physician to the Lithuanian cycling team and team coach Boris Vasilyev were expelled from the games.    The CAS overturned the IOC decision, because bromantan had only recently been added to the prohibited list,  and the athletes and officials were reprimanded.    The Russians had argued that bromantans wasn't a stimulant and thus not banned.  
In addition to its custom DACs, the DA2 has other proprietary features, including: “hardware galvanic isolation for its USB interface,” claimed to “further isolate its USB interface from noisy source power systems”; MFAST, a “high-speed asynchronous jitter removal technology”; MCLK2, a “custom-built, super-accurate clock” that, Meitner says, has been designed specifically for Meitner’s new high-speed DACs; and MDAT2, a digital signal processor that “performs real-time transient detection, processing, and up-conversion of all incoming audio, PCM and DSD, before sending it to the new 16xDSD DACs.” The DSP is implemented with a built-in field-programmable gate array (FPGA). As in all Meitner designs, the digital clock is placed right beside the DACs, where it matters most.
