If I understand the technology correctly, the asychronous USB mode enables the DAC to ask for more data wheneve the buffer is being drawn down. As long as it does that, there is no sonic consequence to the transport of the data into the buffer. The only thing that matters is that the buffer isn't drawn down or overfilled.<br />
<br />
If that is the case, why would the USB cable matter at all? <br />
<br />
And for that matter, another review I read said that the Ayre sounded much better when the reviewer installed more RAM. Why should any characteristic of the computer matter if the DAC is running everything and just ordering up more bits of data as needed?
