I forgot what clock you are using, but doesn't the 957 have a hi z disable pin? It would seem straight forward to implement that feature as a DIY- simply place a grounding switch flip-flop between disables. One would have to swap out clocks however.

They clock we are using does not have a disable pin, but if it is not powered the output is hi z.

Plus if you don't plan on using the on board clock you likely also don't want a shunt reg consuming current it is not using.

The bottom line is if you are going external - you need to commit to that.

Not really a Buffalo question bit it is related...

I'm building a Buffalo SE with Placid HD and Placid HD BiPolar
Started with the Placid HD BP. Manual says about the trimmers: Measure resistance between the two outer pins. (pin 1 and 3 in my picture).
I have don that but the resistance does not change. (stays 9.5K). Trimmer is not installed on the PCB. What am I doing wrong here?

That is because pin 2 is the wiper.. pin 1 and 2 are the far ends of the pot plane, and does because of that have a constant resistance.

You will notice on the board, the wiper pin (2) is shorted to one of the outer pins, which is why you will see adjustment once it is installed.

Default On my...

very slowly progressing (in no hurray, as I am waiting for the new TPA USB interface to complete the project) B-IIIse build I went ahead and installed a low profile socket for the oscillator Trident on the board. This DAC will be built up first on MDF for fine tuning and proof of concept, so I can easily listen in both synchronous and asynchronous modes. With B-II right now I am almost certain I prefer synchronous clocking, but being able to make easy comparisons should help me to be sure.
I must say, it is tempting to go with async operation, just because of the higher flexibility this offers. I just finished upgrading a DAC I built for friend with the B-IIIse board/new Tridents, and set him up with an I2S input (via an LVDS/HDMI board from K&K audio) and SPDIF, with a simple rotary switch for input select on the front panel. I must say the B-IIIse provides a simple and elegant solution for those wanting an I2S and SPDIF input.

I apologize if this has been asked. I read the manual. But it wasn't clear, can I turn off the on board I2C controller and "plug in" a different one (i.e. arudino, etc) later on when I had the time ?
