RE: USB Cable length

From the Ayre website:

USB Cable Requirements

Perhaps the one weakness of USB is that the maximum cable length is somewhat limited, typically 3 meters (~10') to 5 meters (~16'). We have found that one of the most common problems encountered when setting up a USB-based music system is the cable itself. Regardless of any claims from the cable manufacturer, we have found that performance can degrade when exceeding 3 meters. Ayre cannot guarantee the operation or performance of any system utilizing a USB cable longer than 3 meters.

In the case when it is not possible to locate the USB D/A converter within 3 meters of the computer, Ayre has found that the Icron USB extender works well. It is claimed to work up to 100 meters. We have tested it up to 100' and have no reason to doubt their claim. It also operates reliably at speeds up to 192 kHz, even with the asynchronous operation used in the Ayre D/A converters which require concurrent signal transmission in both directions. It is not inexpensive, at around $325 in the US, but a low-cost ($50) USB extender we tested did not function at all with an Ayre USB D/A converter. There may be other similar products that work well, but we have not tested them and cannot verify their performance.
