Default power supply

The AMB power supply is to feed the waveio threw an umbilical cord .A LT1083-5 regulator placed close to the card is the normal choice ,capacity can be much higher and there is no need of crc + isolation transformer.
DPC Latency Checker .check the computer for red spikes .

Now locate your R17 pads on buffaloII ? when looking at the Dac with the twisted pear logos facing upright., you locate the right pad from the 2 R17pads to connect your MCLK live wire only, from WaveIO, then you use the ground wire from your MCLK and connect to left pad of R17 .All your I2S connections from WaveIO to buffaloII will be as short and similar lenght as possible .
hope that helps to synchronize and do convey your results please .

What part number did you use as uBNC to solder on the R17 pads?

Thanks
Do

I took the easy road sorta, i could not find a suitable part number so i connected a extra http://ro.farnell.com/productimages/...1688065-40.jpg that i had on hand to the WaveI/O J5's MCLK, and connected the other end using the center pin with snug fit wire lead then soldered it to the right + pad of the R17, and soldered the other R17 - pad with yet another wire which then connects to the ground of the incoming MCLK .
If more specs, are required then you will have to come over and visualize my setup ,

rol.

Thanks Qusp!

For that price I don't see why I would use the cheaper ones... It's a bargain!

A guess when you buy thousands of those, this is where you start cutting!

no problem. pinnocchio

true, you can save a bit (about 30%) on the cables by buying the cheaper brands like Emerson and TE vs hirose. they are branded under UMC, UMCC and u.fl as far as i can tell these are all identical. i have used emerson and TE cables on u.fl sockets along with the official u.fl type; its a common connection standard these days, there are even some high end PTFE and SPC cables around for a bit more. bloody cheap compared to audiophile or even high quality belden coax thats for sure and it does a better job; however there is only a limited number of connection/disconnection cycles you can use before performance degrades, so only connect when you have set it all up and resist fiddling.

do not be tempted by the w.fl which are thinner and higher bandwidth, but MUCH smaller and not interchangeable. these are used on the ackodac, except for mclk which is u.fl. afaik hirose are the only brand of w.fl so far; last time i looked anyway
