I use a Mutec and I am very happy with it. I use the Mutec 1.2, the smaller version of what you are considering. It passes bit-for-bit and exactly the same word size and clock rate. It passes both PS Audio bit-for-bit test files fine and unit displays the “B” in the upper right had corner. It is as if it is not there.
A thread here where I discussed my use of Mutec: New DS owner, share your experience of the DAC running in from new?
I hook it up to my PC-USB-Mutec-XLR-DirectStream Junior. I have compared this hookup to my PC-USB-DirectStream and I can not hear a difference. The display on the DirectStream shows the exact same information (rate/bit) etc. regardless if the Mutec is in the chain or not.
The reason I have the Mutec is simply for convenience. I had the Mutec prior to the direct stream because I needed a USB interface and a re-clocking unit between my PC and my Accuphase CD Player (has digital ins). The Accuphase is really suseptible to jittre hence the desire for this Mutic unit. Now with the DirecStream, I don’t need it but, it allows me to hook up three DACs at once for cool A/B/C comparisons since the Mutec presents a bunch of live digitial outs. So I can then hook up each DAC to it, and then from each DAC, I go to my integrated amp where I can simply switch between them while they are all playing the exact same source stream… cool.
Said again, I find the Mutec 1.2 a very handy device that has no down side at all that I am aware of either in sound or functionality from my DirectSTream.
