Not aware of anyone that has done a direct comparison between these DACs (and I have been reading up quite a bit on DACs). If I had to roll the dice and buy blind I would get the MSB. Another contender is the Bel Canto 3.5vb with the external powersupply. Stereophile compared the Weiss, dCS and Bel Canto, and preferred the Bel Canto (also the cheapest).
