A few info back from our German colleagues :
I tried to converse on the German forum, which was not that easy for me given my lack of mastering the German language ; Google Translate is your friend to a certain but limited extent :-). I am anyhow happy to share a few information I gathered there, especially from Fujak, the person who tested Mutec MC-3+ cascades.
- on the possibility to use an external 10 MHz clock ; Fujak has built his own external clock and stated that he was not able to witness any improvement with this DIY clock fed into the MC-3+ USB, compared to a cascade of 2 x MC-3+ USB devices. Fujak did not report being able to test a prototype of the Ref10 from Mutec anyhow. We will see what that brings when this new product will be available.
- on the cascading of 2 x MC-3+ USB devices ; Fujak strongly recommends to use BNC connections between the devices and to the DAC (better quality for the buck of BNC cables than AES ones). He uses Oyaide DB-510 cables to do that. Kujak made the precision that the two MC-3+ USB need to be configured with internal clock reclocking (using the clock signal from the first to synchronize the second does not help reach better SQ).
- on the upsampling question I was raising (24/192 before reclocking instead of 16/44 to the reclocker and upsampling at the DAC) : there are other reports by the German forum users that upsampling to 24/192 before a 24/192 DAC brings better SQ. There is an ongoing thread on this subject.
Hope this helps.
