You don’t give specs as to what dBFS or psec your product is; you’ve stated 7psec before, so I’ll assume that, the ChromeCast Audio has less than 4psec (better than -275dBFS / 45Bit). If your product is better, I’ll retract my statement. Again though, even if your re-clocker was 0psec, the differences are not even close to audible, so spending $700 one one would be waste of money in this instance.
Even the $100 Khadas Tone board DAC has a J-test result of -135dBFS, which allows for more dynamic range than we can hear in a room (say 140dB max and a room noise floor of 30dB, so 110dB; and that 140dB is generous, most music is mastered to 105dB, with some orchestral/classical getting to 120dB).
A ChromeCast Audio hooked up to a “cheap” Topping D50 DAC, using normal cables, produced a J-test of better than -130dBFS, also better than our hearing in a room.
