Another option for an outboard DAC that uses the Sabre DAC chipset is the new Audiolab M-DAC... http://www.audiolab.co.uk
I just (pre)ordered one from the North American distributor (Planet of Sound, in Toronto), based solely on the Pink Fish Media forum discussions (with input from John West, the designer). The specs and features compare very favorably to the W4S and Eastern Electric DAC's, at a lower price point. Early reviews have been favorable, but not much feedback yet, as few units have been shipped.
