Cary Xciter DAC

[dminches]

Is anyone using one of these with a USB input? If so, what is the maximum sampling frequency it will accept? I am trying to use it with jriver and I keep getting an error stating that I am limited to 24/48. The unit seems to indicate that it will accept up to 24/192 but that may not be via USB.

Any help would be appreciated.

David, from Page 6 of the Xciter Dac manual:

The USB 2.0 input receives a 24-48kHz data stream, which bypasses the receiver chip and is sent
directly to the CM-108 device. This stream is then stripped as the bus separates the clock and
data signals, resulting in a connection with an extremely low noise floor where jitter is almost
nonexistent. This re-clocked stream is directed by the on-board software of the Xciter DAC to
the main AK4399, 32-bit, 192kHz processor chip, then out to the rear panel, single-ended RCA
analog output jacks.

It appears that, for USB, 48 is the limit. It may upsample to 192; from Pg. 12:
MACINTOSH – AUDIO MIDI SETUP

Macintosh computers have a utility for adjusting how audio is handled on the computer. This
utility is called Audio MIDI Setup and is located in the “Utilities” folder. Settings for default input
and output devices are set here, as well as certain parameters for the device in use. To check or
adjust the settings for the Xciter DAC, select “C-Media USB Headphone Set” from the “Properties
For” menu when using a USB connection. On the right side of the window you will see details of
the audio output settings of the Xciter DAC. Under this output section, you can adjust the output
frequency from 44.1kHz to 48kHz. Adjustments to the bit depth of the audio can also be adjusted
here from 16 to 24 bit.

I love the AKM4399 chip! I hope this helps.

Thanks Eric. I stumbled across that last night. Bummer!

A waste of a great DAC chip for sure.....
