Well, the Metrum did metion that about 1 in 100 samples will play 192khz, but that he specs them for 176.4. In his words, it's extremely unlikely for someone to end up with a unit that will process 192khz. Either both yours and Srajan's are the 1/100 sample, but the chances of that are, well, 1/10,000. Or, something else is going on; I don't know, but that's how Metrum explained it to me
