Hi all,
This is the Master Clock thread as You all well know. I now feed most of my digital stuff with my Mutec REF10 SE120.
I have a bunch of dac's both from Audio-gd & Gustard and also a few of other brands. I have been buying and testing and selling alot of them. I think both Audio-gd (Kingwa) and the Gustard team does a brilliant job in their designs to get a significant performance lift in their gears using good External Master clocks.
Where I am, there is no way back without the EXT XO 10MHz (Master clock). I knew pretty fast in my "research" or investigating if You like regarding these clocks and the impact of them that a high end clock with many outputs is right for me.
So where is this heading... Well, to the area where I haven't (yet) been using the synchronized time pulse in, I meaning in the digital music streamers. This is not 100% true because I use the internal renderers in the Gustard (R26 and A26 using masterclock). Beside those I use Raspberry Pi 3B+ and 4B's using their own passive oscillators and the linux based piCorePlayer software since many years.

@FredA have found a nice device named C19 and it is based on the CM4 board (Rasperry Pi 4). For me this was new info. This is a ready to go device where You can choose onboard OCXO or prepared for 10MHz Master clock input. I ordered one too after
@FredA 's very positive comments on its performance. For me, with this in place, I will have a full digital chain sharing the Mutec 10MHz clock pulse. I don't think it can be much better

p.s. I also found an addon board for the RaspBerryPi 4B. To get it to work there are risks to damage Your 4B board but I will give it a try. This is not for low skilled DIY-guys/gals
