Thank you for your interest in our Three-Two USB DAC. Unfortunately, due to other commitments we won't be able to manufacturer any new Three-Two USB DACs for the foreseeable future, but we are exploring possible licensing arrangements with other manufactures. If you would like to be informed of any future Asynchronous USB DAC products based on this technology send us an email at asyncusb@cooper-street.com to be added to a mailing list. We apologize for any inconvenience we may have caused.
