Srajan, the newest streamer from HiFi Rose has what may be an industry first unless I am mistaken: an internal OCXO clock. I've always thought an OCXO clock had to be in a separate box as it needs to be on 24/7 for optimum performance. All the best, Michael
For one easy example, the Denafrips Terminator DACs have temperature-controlled crystal oscillators inside. So do many top DACs. There's nothing inherent in the concept that requires being offboard. Such parts simply take a certain amount of time to hit their ideal temperature. So owners of internal OXCO are advised to not turn those components off for best performance. In that regard there's nothing whatsoever unique about the Hifi Rose. It might well have other unique specs but that one isn't. Think of it like a precision bias controller or thermal tracker in an amplifier to insure that the output transistors operate at ideal temperature. You'd not want such a controller outside the amplifier. An oven-controlled clock is essentially a normal clock with a thermal control circuit to create the most stable operating conditions. Where such a clock sits (inside or outside the DAC or player) is immaterial to that aspect though as you well know, experts like Ed Meitner and Eelco Grimm are firm that for best performance, clocks belong inside as close as possible to their associated DAC chips.
